description: Durch die in diesem Artikel vorgestellte kombinierte Betrachtungsmethode lassen sich flankiert durch die Oberflächenanalyse alle Orte einer (Reibungs-)Kontaktfläche finden, bei denen entweder aufgrund der Topographie oder der Mikrostruktur Bereiche auftreten, an denen mit Verschleiß zu rechnen ist. Dies würde sofort eine gezielte Optimierung durch werkstoff- und fertigungstechnische Maßnahmen ermöglichen.
description: In this contribution, experimental
and numerical experiments showed
that the contact area must be subdivided
into the nominal and the real
one in order to understand the influence
of topography on friction and
wear at ultra-mild wear rates. The
dissipated energy depends on any
local contact situation within the real
contact area, which can be approximated
by means of the ‘half-space’
method. Still, neither a standardized
surface parameter nor the coefficient of friction provides sufficient information
about the tribological performance.
The surface topography alters
during running-in and, therefore,
the dissipative characteristics. The
complex relationships between the
machining strategy, the obtained surface
topography, and microstructural
alterations are still not fully understood
as to their influence on the
tribological performance. But, following
the proposed methodology,
the contact in regards to the localization
of the highly loaded areas can
be evaluated. In combination with
sound surface and subsurface analyses,
a well-aimed optimization of the
tribological system is possible.

description: COMPARISON OF ALBUTEROL DELIVERY BETWEEN HIGH FREQUENCY OSCILLATORY VENTILATION AND CONVENTIONAL MECHANICAL VENTILATION IN A SIMULATED ADULT LUNG MODEL USING DIFFERENT COMPLIANCE LEVELS  By  Waleed A. Alzahrani, BSRT    BACKGROUND: Delivery of aerosol by pMDI has been described with conventional mechanical ventilation (CMV) but not with high frequency oscillatory ventilation (HFOV). The purpose of this study was to compare aerosol delivery to a simulated 75 kg adult with low compliance during both CMV and HFOV.  Since actuation of pMDI with inspiration is not feasible with HFOV, we investigated the impact of actuation timing only during CMV.  METHOD: CMV (Respironics Esprit) and HFOV (Sensor Medics 3100B) ventilators with passover humidifiers and heated circuits were connected by 8 mm ID ETT and filter (Respirgard II, Vital Signs) to a test lung (TTL) with compliance settings of 20 and 40 ml/cm H2O in order to simulate a non compliant lung. Settings for CMV (VT 6 ml/kg, I:E 1:1, PEEP 20 cm H2O, and RR 25/min), and HFOV (RR 5 Hz, IT 33%, ?P 80 cm H2O and mPaw 35 cm H2O) were used, with similar mPaw on CMV and HFOV.  Parameters were selected based on ARDSnet protective lung strategy (Fessler and Hess, Respiratory Care 2007)  Eight actuations of albuterol from pMDI (ProAir HFA, Teva Medical) with double nozzle small volume spacer (Mini Spacer, Thayer Medical) placed between the ?Y? adapter and ETT at more than 15 sec intervals for each condition (n=3). During CMV, pMDI actuations were synchronized (SYNC) with the start of inspiration at more than 15 s, and nonsynchronized (NONSYNC) with actuations at 15 s intervals. Drug was eluted from the filter and analyzed by spectrophotometry (276 nm). Repeated measures ANOVA, pairwise comparisons and independent t- tests were performed at the significance level of 0.05.   RESULTS: In all cases, aerosol delivery was greater with HFOV than CMV (p<0.05). Synchronizing pMDI actuations with the beginning of inspiration increased aerosol deposition significantly at compliance levels 20 ml/cm H2O and 40 ml/cm H2O (p=0.011 and p=0.02, respectively). Lung compliance and aerosol delivery are directly related. Increasing lung compliance to 40 ml/cmH2O improved aerosol delivery during CMV and HFOV (p<0.05).  CONCLUSION: Albuterol deposition with pMDI was more than two fold greater with HFOV than CMV in this in-vitro lung model. Changing lung compliance has almost 2 fold impact on aerosol delivery during both modes of ventilation. Furthermore, synchronizing pMDI actuations during CMV improved aerosol delivery up to 4 fold.

The Effect of Different Interfaces on Aerosol Delivery in Simulated Spontaneously Breathing Adult with Tracheostomy
Creators: name: Bugis, Alaa
Publisher: name: Georgia State University
Year: 2010

description: Background: The delivery of an aerosol via a tracheostomy tube has been previously described with both a tracheostomy collar and a T-piece, but not with a Wright mask, or aerosol mask. The primary purpose of this study was to quantify lung doses using different interfaces: tracheostomy collar, Wright mask, and aerosol mask. The secondary purposes were to compare albuterol delivery between an opened vs. a closed fenestration hole and also to determine the effect of inspiratory time:expiratory time (I:E) ratio on aerosol delivery.

Methods: A teaching mannequin (Medical Plastic Labs, Gatesville, TX) with a tracheostomy opening was used. Two of the mannequin's bronchi were connected to a "Y" adaptor, which was attached to a collecting filter (Respirgard ? II 303, Vital Signs, Englewood, CO), which was connected to a breathing simulator (Harvard Apparatus Dual Phase Control Respirator Pump, Holliston, MA) through a corrugated tube. Settings for spontaneous breathing were respiratory rate 20/min, and tidal volume 400 mL. The I:E ratios were adjusted in the first and second comparisons at 2:1 and 1:2, respectively. The nebulizer was operated by a flow meter (Timemeter, St. Louis, MO) at 8 L/min with 100% oxygen. In every condition, the flow was discontinued at the end of nebulization. The nebulizer was attached to the tracheostomy collar (AirLife?, Cardinal Health, McGaw Park, IL) in the first group, the Wright mask (Wright Solutions LLC, Marathon, FL) in the second group, and the aerosol mask (AirLife?, Cardinal Health, McGaw, IL) in the third group. Drug was eluted from the filter and analyzed by spectrophotometry (276 nm).

Data Analysis: Paired t-test, one-way analysis of variance (ANOVA), repeated measures ANOVA, post-hoc and pairwise comparisons were performed at the significance level of .05, using PASW version 18.0.

Results: Aerosol delivery was greater with the tracheostomy collar than the Wright mask and aerosol mask (p < .05). Closing the fenestration hole increased aerosol deposition significantly at 2:1 ratio (p = .04) compared to opening the fenestration at 1:2 ratio. I:E ratio and aerosol delivery were directly related. Increasing I:E ratio from 1:2 to 2:1 improved aerosol delivery significantly with tracheostomy collar-fenestration opened (p = .009), Wright mask (p = .02) and aerosol mask (p = .01).

Conclusion: This study indicates that the use of a tracheostomy collar is the best method of delivering aerosol therapy among the three interfaces. The I:E ratio of 2:1 caused greater aerosol deposition than 1:2 ratio. The aerosol deposition was better when the fenestration hole was closed compared with opened fenestration.

description: Aerosol administration via small-volume nebulizers are still being used by selected patient-population. In the economic market, several nebulizer designs have become available, with each incorporating unique features that will potentially establish it as the preferred choice in aerosol delivery. With the continuous rising cost of health care services, clinicians are faced with the task of identifying opportunities for cost reduction in respiratory care. PURPOSE: The purpose of this study was to conduct a cost-benefit analysis of dosimetric nebulization using the Circulaire system and the traditional VixOne nebulizer. The desired outcome was to elevate awareness of the potential impact of the Circulaire, and how its adoption might reduce costs and enhance productivity in respiratory care. METHODS: A retrospective study using existing data collected from an urban tertiary adult hospital with a Level II Trauma Center was completed. DATA ANALYSIS: Descriptive statistics were run for each variable. The total cost of a full-time Registered Respiratory Therapist (RRT) with benefits per hour was calculated. The average number of RRTs per 12-hour shift, average number of nebulizer treatments by an RRT per 12-hour shift, average costs of traditional VixOne nebulizer and the Circulaire system were also calculated. RESULTS: Descriptive statistics indicated the annual cost of delivering aerosol therapy using the traditional VixOne nebulizer at 9-minutes treatment time to be $114,263.25 per year. The Circulaire was compared at two different treatment times of 5-minutes and 3-minutes, and the annual costs were $137,422.50 per year and $116,982.50 respectively. A sensitivity analysis was also conducted, and the treatment load was increased by 30%, with a reduction to 5 RRTs per shift. Data indicated an annual savings of 8% with the Circulaire at 5-minutes treatment time, and 21% with the Circulaire at 3-minutes treatment time. CONCLUSION: The use of the Circulaire system at 5-minutes or 3-minutes treatment time can reduce department expenditure by reducing labor costs.
Efficiency of Aerosol Therapy through Jet Nebulizer, Breath-Actuated Nebulizer, and Pressurized Metered Dose Inhaler in a Simulated Spontaneous Breathing Adult

description: BACKGROUND: Aerosol therapy using albuterol is one of the most prescribed asthma treatments. The most frequently used methods of aerosol delivery are pneumatic jet nebulizer (JN), pressurized metered-dose inhaler (pMDI), and breath-actuated nebulizer (BAN). Choosing among these devices is usually not based on thorough comparison of efficiency or cost. We compare the efficiency of these three devices using a spontaneously breathing adult model. 
METHODS: We connected each aerosol generator?JN, BAN, or pMDI with a valved holding chamber (VHC)?to the face of an adult teaching manikin. Below the bifurcation, an elbow adaptor was connected to a corrugated tube and was angled to be at a lower level than the collecting filter to prevent droplets from dripping directly into the collecting filter. From the collecting filter, another corrugated tube was connected to a prevention filter, which was then connected to an adult breathing simulator. Spontaneous breathing parameters were VT 450 mL, RR 20/min, and I: E ratio 1:2. First, we compared JN, BAN (2.5 mg/3 mL), and pMDI (4 puffs); second, we compared JN and BAN 2.5 mg/0.5 mL plus 0.5 mL normal saline. Data were analyzed using spectrophotometry (276 nm). One-way ANOVA and independent sample t-tests were used (p<0.05).
RESULTS: There were no differences in inhaled mass percentage (p=0.172) JN, BAN, and pMDI in the first experiment. Treatment time with BAN was significantly longer (p=0.0001) than with JN or pMDI. In the second experiment, BAN delivered more medication (p=0.004) than jet nebulizer. Treatment time was significantly less with JN (p=0.010). There was no difference in residual volume among JN and BAN in both experiment (p=0.765, p=0.115).
CONCLUSIONS: All the devices that were compared using a 3 ml or 4 pMDI puffs delivered comparable amount of medication with no significant difference. However, BAN using 1ml fill volume delivers more drug compared to JN. Additionally, treatment time was longest with BAN. Even with reduction of its filling volume, BAN delivers a higher amount of medication to that of pMDI but was not statistically significant.

The Effect of Using Different Aerosol Devices and Masks on Aerosol Deposition during Noninvasive Positive Pressure Ventilation in an Adult Lung Model
Creators: name: AlQuaimi, Maher
Publisher: name: Georgia State University
Year: 2011

description: Introduction: Although patients with an acute increase in airflow resistance may require aerosol therapy and noninvasive positive pressure ventilation (NIPPV), the efficiency of different aerosol devices and masks during NIPPV is not well understood. The purpose of this study was to determine the efficiency of a jet nebulizer (JN), a vibrating mesh nebulizer (VMN) and a pressurized metered-dose inhaler (pMDI) and three different masks during NIPPV.
Method: An in vitro lung model consisted of the upper airway of an adult teaching manikin with a collecting filter at the level of the bronchi attached to a passive test lung. NIPPV was administered via full face mask for the first experiment (AF531 oro-nasal) with an IPAP/EPAP of 20/5 cm H2O and a respiratory rate of 15 Breath per minute (BPM). Aerosol generators were placed between the leak in the circuit and the mask. Albuterol sulfate (2.5 mg/ 3 ml) was nebulized with the JN (Micromist) and the VMN (Aeroneb Solo). Four puffs (108 æg/puff) were administered with the pMDI (ProAir HFA) with a spacer (Aerovent) that first was placed in the recommended normal position (pMDI-N) with aerosol plume directed towards patient, and then in the reversed position (pMDI-R), with aerosol directed away from patient (n=3). In the second experiment, three masks were used 1) the Performax mask, 2) the AF531 oro-nasal mask, and 3) the Performa track mask.  Performa track mask was tested with only Aeroneb solo while other masks were tested with both Aeroneb solo and NIVO VMNs. In both experiments, filters were eluted with 0.1 HCl and analyzed by a spectrophotometer at 276 nm. Residual volumes were determined gravimetrically.
Result: Descriptive statistics, one-way analysis of variance (ANOVA), and independent t tests were used. Statistical significance was set at p<0.05. During NIPPV, inhaled mass (IM) and inhaled mass percent (IM %) varied significantly (p=0.042 and p=0.028, respectively). Aerosol delivery with the JN was the lowest during NIPPV. The VMN has a significantly lower residual volume than the JN (p=0.0001). No statistical difference in efficiency was found between the two pMDI orientations (p=0.253). In the second experiment, oro nasal mask with Aeroneb Solo VMN results in the highest IM which was significant when compared with all other masks(p=0.0001). No statistical difference can be found between other masks.
Conclusion: The JN was less efficient than the VMN and the pMDI in either orientation. The type of aerosol device used during NIPPV influenced aerosol delivery in this simulated adult lung model. Oro nasal mask with Aeroneb Solo VMN provided the highest IM.

description: At have et godt datagrundlag bliver vigtigere og vigtigere. Tidligere er størstedelen af arbejdet med trafikplanlægning baseret på simple trafiktællinger og/eller uheldsstatistiker. De senere år er det blevet muligt at indsamle data ved en række forskellige metoder, bl.a. 3D kameraer, der kan give detaljerede data om trafiktal, adfærd, konflikter osv. NIRAS har på flere opgaver samarbejdet med Viscando, og benyttet deres 3D kameraer og tilhørende software i forbindelse med trafikanalyser. Systemet har bl.a. været brugt til at udarbejde en OD-matrice til brug i en trafiksimulering af en tosporet rundkørsel og til konfliktstudier i et firbenet kryds. Erfaringerne med systemet viser en række fordele, bl.a. er det muligt at have en relativt lang dataindsamlingsperiode, hvorved f.eks. konflikter og udsving i trafikken kan registreres. Dette medfører, at det er muligt identificere mønstre mv. i dataene, hvilket er fordelagtigt i løsningsarbejdet. Derudover giver udstyret flere typer af data, og det er muligt at undersøge kombinationsmuligheder efterfølgende, hvis der i analysearbejdet viser sig andre alternativer, som kunne være interessante at undersøge.

description: It has been suggested that cognitive and affective factors related to interpersonal aggression could be similarly used to understand and explain stalking behaviour. This thesis presents research examining whether cognitive and affective factors identified as relevant to aggression and stalking, respectively, can differentiate between people who stalk and those who engage in interpersonal aggression (e.g, physical assault) but not stalking. Findings from this research will be used to inform the development of theories of stalking behaviour, and psychological interventions for stalking behaviour.

Creators: name: Almasoudi, Bandar
Publisher: name: Georgia State University
Year: 2012

description: BACKGROUND: Although Problem-based learning (PBL) approach is a common teaching technique in medical education, its use in the field of respiratory therapy is somewhat controversial. With so many programs adopting PBL strategies, it is important to examine whether there are differences between PBL and traditional teaching approaches in regards to learning outcomes. Therefore, the purpose of this study was to investigate if there are any significant differences between PBL and lecture-based program students in their cognitive abilities in mechanical ventilation.
METHODS: Two universities with BS programs in respiratory therapy were chosen?one uses PBL (15 participants) and on uses lecture-based method (24 participants). All 39 participants were given10 multiple-choice questions related to mechanical ventilation derived from the NBRC RRT written exam forms (C & D) as a pre and a post test.
RESULTS: The dependent t-test showed a significant difference between the pre and post test of the lecture-based and the PBL groups, resulting in a p value of 0.006 and 0.025 respectively. The independent t-test showed a significant difference in the pre-test favoring the lecture-based group (p = 0.039). However, the independent t-test showed no significant difference in the post-test (p=0.085)
CONCLUSIONS: PBL is increasing in popularity despite the fact that studies of its efficacy have been thus far inconclusive. This study has shown PBL to be effective, but not significantly more effective than traditional lecture-based methods in regards to objective test scores.

In-Vitro Comparison of Aerosol Drug Delivery in Pediatrics Using Pressurized Metered Dose Inhaler, Jet Nebulizer, and Vibrating Mesh Nebulizers
Creators: name: Al Sultan, Huriah
Publisher: name: Georgia State University
Year: 2012

description: Background: Aerosol therapy has been established as an efficient form of drug delivery to pediatric and adult patients with respiratory diseases; however, aerosol delivery to the pediatric population is quite challenging. While some studies compare jet nebulizer (JN), vibrating mesh nebulizer (VMN), or JN and pMDI, there is no study comparing these three devices in pediatric and young children. The aim of this study quantifies aerosol deposition using JN, VMN, and pMDI/VHC in a simulated pediatric with active and passive breathing patterns.
Methods: Each aerosol generator was placed between manual resuscitator bag (Ambu SPUR II Disposable Resuscitator, Ambu Inc, Glen Burnie, MD) and infant facemask (Mercury Medical, Cleanwater, FL), which was held tightly against the SAINT model. Breathing parameters used in this study were Vt of 100 mL, RR of 30 breaths/min, and I:E ratio of 1: 1.4. Active and passive breathing patterns were used in this study with aerosol device; active breathing pattern was created using a ventilator (Esprit Ventilator, Respironics/Philips Healthcare, Murrysville, PA) connected to a dual chamber test lung (Michigan Instruments, Grand Rapids, MI), which was attached to an absolute filter (Respirgard II, Vital Signs Colorado Inc, Englewood, CO), to collect aerosolized drug, connected to the SAINT model. Pediatric resuscitator bag was run at 10 L/min of oxygen and attached to aerosol generator with facemask. In passive breathing pattern, SAINT model was attached to test lung and ventilated using the resuscitator bag with the same breathing parameters. Each aerosol device was tested three times (n=3) with each breathing patterns. Drug was eluted from the filter and analyzed using spectrophotometry. The amount of drug deposited on the filter was quantified and expressed as a percentage of the total drug dose. To measure the differences in the inhaled drug mass between JN, VMN, and pMDI/VHC in active or passive breathing, one-way analysis of variance (one-way ANOVA) was performed. To quantify the difference in aerosol depositions between the two breathing patterns, independent t-test was performed. A p < 0.05 was considered to be statistically significant.
Results: Although the amount of aerosol deposition with the JN was the same in passive and active breathing without any significant difference, the VMN was more efficient in active breathing than the JN (p = 0.157 and p = 0.729, respectively). pMDI/VHC had the greatest deposition in the simulated spontaneous breathing (p=0.013)
Conclusion: Aerosol treatment may be administered to young children using JN, VMN, or pMDI/VHC combined with resuscitator bag. Using pMDI/VHC with resuscitator bag is the best choice to deliver albuterol in spontaneously breathing children. Further studies are needed to determine the effectiveness of these aerosol generators with different type of resuscitator bag and different breathing parameters.

description: Background: HFNC system is a novel device used with aerosol therapy and seems to be rapidly accepted. Although there are some studies conducted on HFNC and vibrating mesh nebulizer, the effect of HFNC on aerosol delivery using jet nebulizer or pressurized metered-dose inhaler (pMDI) has not been reported. In an effort to examine the effect of HFNC on aerosol deposition, this study was conducted to quantify aerosol drug delivery with or without a HFNC using either pMDI or jet nebulizer.
Methodology: The SAINT model, attached to an absolute filter (Respirgard II, Vital Signs Colorado Inc., Englewood, CO, USA) for aerosol collection, was connected to a pediatric breathing simulator (Harvard Apparatus, Model 613, South Natick, MA, USA). To keep the filter and the SAINT model in upright position to collect aerosolized drug, an elbow adapter was connected between the absolute filter and the breathing simulator. An infant HFNC (Optiflow, Fisher & Paykel Healthcare LTD., Auckland, New Zealand) ran at 3 l/min O2 was attached to the nares of the SAINT model. Breathing parameters used in this study were Vt of 100 mL, RR of 30 breaths/min, and I:E ratio of 1: 1.4. Aerosol drug was administered using: 1) Misty-neb jet nebulizer (Allegiance Healthcare, McGaw Park, Illinois, USA) powered by air at 8 l/min using pediatric aerosol facemask (B&F Medical, Allied Healthcare Products, Saint Louis, MO, USA) to deliver albuterol sulfate (2.5 mg/3 mL NS), and 2) Four actuations of Ventolin HFA pMDI (90 ?g/puff) (GlaxoSmithKline, Research Triangle Park, NC, USA) combined with VHC (AeroChamber plus with Flow-Vu, Monaghan Medical, Plattsburgh, NY, USA). Aerosol was administered to the model with and without the HFNC and another without (n=3). Drug was collected on an absolute filter, eluted and measured using spectrophotometry. Independent t tests were performed for data analysis. Statistical significance was determined with a p value of <0.05.
Results: The mean inhaled mass percent was greatest for pMDI with (p = 0.0001) or without HFNC (p = 0.003). Removing HFNC from the nares before aerosol treatment trended to increase drug delivery with the jet nebulizer (p = 0.024), and increased drug delivery by 6 fold with pMDI (p = 0.003).
Conclusions: Aerosol drug may be administered in pediatrics receiving HFNC therapy using either jet nebulizer or pMDI. However, using pMDI, either with or without HFNC, is the best option. When delivering medical aerosol by mask, whether by jet nebulizer or pMDI, removing HFNC led to an increase in inhaled mass percent. However, the benefit of increased aerosol delivery must be weighed against the risk of lung derecruitment when nasal prongs are removed.

description: Purpose: Although the public’s level of concussion awareness is increasing, there are still instances where youth play through concussion symptoms and where parents do not take their child with a suspected concussion to a physician for assessment and clearance. This study uses qualitative methodology to explore parent and coach experiences with concussion management in youth ice hockey and highlights potential barriers and facilitators to a coach removing a player from play due to a suspected concussion and parents taking their child to see a physician. Methods: Twenty-four hockey parents and coaches from Calgary participated in semi-structured interviews that explored participants’ experience with managing hockey concussion. Using thematic analysis, key barriers and facilitators to coaches appropriately removing a player from play and parents taking their child to see a physician were identified. Results: Some barriers to a coach removing a player from a game included not having the ability to perform an assessment in their role as coach and relying on the player to report their symptoms. An obvious severe mechanism of injury and established association protocols were identified as facilitators to a coach removing a player with a suspected concussion from play. Some barriers to physician follow-up included parents’ beliefs that the concussion symptoms were not severe and physician availability. Conclusions: Coaches, parents and players play a vital role in facilitating identification and appropriate concussion management. While further education of coaches and parents is indicated, it is important to also consider contextual factors that interfere with concussion management decisions.

description: The report analyses relevant to XR EU legislations (twenty five in total), clustered into privacy and data, intellectually property, consumer and competition law, media and online services, cybersecurity, accessibility and non-discrimination, sectoral law, technology law, and finance law. The gap analysis highlights the scope, subjects, main provisions and applicability of each regulation to the XR sector. The challenges that XR technologies are faced with are discussed in terms of barriers, uncertainties and conflicting requirements in the existing regulatory landscape. The analysis reveals a multi-faceted regulatory framework impacting all entities and all sectors that provide XR products or services to the European market. XR technologies often introduce novel concerns or newer dimensions of existing concerns. The processing of biometric personal data, the potential of identity theft online or the role of data inequality, highlight the importance of technology-neutral laws that can accommodate these newer dimensions of normatively understood concerns. The pace of XR technological developments is overtaking the ability of policy making to offer adequate regulatory coverage of the issues they bring up to the forefront. There is therefore a need to foster adaptable regulations that can be readily updated in tandem with the development of XR technologies. The regulatory gap analysis provides the backbone for the forthcoming policy roadmap to ensure a comprehensive and ethical XR technology development.

A Survey of Preceptor Training in Clinical Education of Respiratory Care Departments in Selected Hospitals in Metropolitan Atlanta
Creators: name: Aljasser, Tariq
Publisher: name: Georgia State University
Year: 2012

description: Preceptorship is the ideal method for teaching students in the healthcare environment. Due to a shortage of staffing, respiratory care students are not often assigned with preceptors, rather they are assigned with respiratory care staff that has minimal to no formal training in education. Therefore, students may not receive appropriate role involvement, decision-making and patient skills experience. PURPOSE: The purpose of this study was to examine the current methods of preceptor training and evaluate the need for a preceptor-training program according to the education coordinators and respiratory care directors/managers. METHODS Data were acquired through a descriptive survey. The survey was formulated and sent using the online survey generator Zoomerang. The survey was submitted to a convenience sample of department directors, department education coordinators, and staff at clinical affiliates associated with Georgia State University. RESULTS: Thirty-six participants were surveyed with a response rate of 67%. Forty-eight percent were a respiratory director/manager, 35% education coordinator and 9% supervisor. Eighty-six percent of participants work in not-for-profit hospitals. Seventy-nine percent of participants believe there is a need for a standardized preceptor-training program, however, only 64% reported that preceptors receive training prior to receiving students. CONCLUSION: There is a need for a standardized preceptor-training program for respiratory therapists to improve the quality of clinical education provided to respiratory therapy students.
The Effect of Aerosol Devices and Administration Techniques on Drug Delivery in a Simulated Spontaneously Breathing Pediatric Model with a Tracheostomy
Creators: name: Alhamad, Bshayer
Publisher: name: Georgia State University
Year: 2013

description: Background: Evidence on aerosol delivery via tracheostomy is lacking. The purpose of this study was to evaluate the effect of aerosol device and administration technique on drug delivery in a simulated spontaneously breathing pediatric model with tracheostomy.
Methods: Delivery efficiencies during spontaneous breathing with assisted and unassisted administration techniques were compared using the jet nebulizer (JN- MicroMist), vibrating mesh nebulizer (VMN- Aeroneb Solo) and pressurized metered-dose inhaler (pMDI- ProAirHFA). The direct administration of aerosols in spontaneously breathing patients (unassisted technique) was compared to administration of aerosol therapy via a manual resuscitation bag (assisted technique) attached to the aerosol delivery device and synchronized with inspiration. An in-vitro lung model consisted of an uncuffed tracheostomy tube (4.5 mmID) was attached to a collecting filter (Respirgard) which was connected to a dual-chamber test lung (TTL) and a ventilator (Hamilton). The breathing parameters of a 2 years-old child were set at an RR of 25 breaths/min, a Vt of 150 mL, a Ti of 0.8 sec and PIF of 20 L/min. Albuterol sulfate was administered with each nebulizer (2.5 mg/3 ml) and pMDI with spacer (4 puffs, 108 æg/puff). Each aerosol device was tested five times with both administration techniques (n=5). Drug collected on the filter was eluted with 0.1 N HCl and analyzed via spectrophotometry.
Results: The amount of aerosol deposited in the filter was quantified and expressed as inhaled mass and inhaled mass percent. The pMDI with spacer had the highest inhaled mass percent, while the VMN had the highest inhaled mass. The results of this study also found that JN had the least efficient aerosol device used in this study. The trend of higher deposition with unassisted versus assisted administration of aerosol was not significant (p>0.05).
Conclusions: Drug deposited distal to the tracheostomy tube with JN was lesser than either VMN or pMDI. Delivery efficiency was similar with unassisted and assisted aerosol administration technique in this in vitro pediatric model.
The effect of fluctuating pore pressure to geotechnical strength during screw pile installation and testing
Creators: name: Verumandy, Kanagesperan
Publisher: name: Swinburne
Year: 2024

description: Screw piles is an economical deep foundation system in construction sites involving cut and fill methods. With imported fills overlying high-bearing capacity layers or where in-situ layers are of low bearing capacity, screw piles can extend the load transfer mechanism from the top low-bearing capacity layer to the lower stronger layers thus distributing stress and minimizing strain. This results in minimal soil settlement and therefor post-construction movements in buildings are mitigated. The main benefits of screw pile foundations include shorter turnaround time, ease of installation, ease of access and removal when foundations are no longer required.

Comparison of HFNC, Bubble CPAP, and SiPAP on Aerosol Delivery in Neonates: An In-Vitro Study
Creators: name: Sunbul, Fatemah
Publisher: name: Georgia State University
Year: 2013

description: Background: Aerosol drug delivery via high flow nasal cannula (HFNC), bubble continuous positive airway pressure (CPAP), and synchronized inspiratory positive airway pressure (SiPAP) has not been quantified in spontaneously breathing premature infants. The purpose of this study was to compare HFNC, bubble CPAP, and SiPAP on aerosol delivery in a simulated spontaneously breathing preterm model.
Methods: A breath simulator was set to preterm infant settings (VT: 9 ml, RR: 50 bpm and Ti: 0.5 sec) and connected to the trachea of an anatomical upper airway model of a preterm infant (DiBlasi) via collecting filter distal to the trachea. The HFNC (Fisher & Paykel), Bubble CPAP (Fisher & Paykel), and SiPAP (Carefusion) were attached to the model via their proprietary nasal cannula and set to deliver 5 cm H2O pressure. Albuterol sulfate (2.5 mg/0.5 mL) was aerosolized with a mesh nebulizer (Aeroneb Solo) positioned (1) proximal to the patient and (2) prior to the humidifier (n=5).The drug was eluted from the filter with 0.1 N HCl and analyzed via spectrophotometry (276 nm). Data were analyzed using descriptive statistics, t-tests, and analysis of variance (ANOVA), with p
Results: At position 1, the trend of lower deposition across devices was not significant; however, in position 2, drug delivery with SiPAP was significantly lower compared to both HFNC (p=0.003) and bubble CPAP (p=0.008).Placement of the nebulizer prior to the humidifier increased deposition with all devices (p<0.05).
Conclusion: Aerosol can be delivered via all three devices used in this study; however, delivery efficiency of HFNC is better than the other CPAP devices tested. Device selection and nebulizer position impacted aerosol delivery in this simulated model of a spontaneously breathing preterm infant.
