title: Lung analysis in children mechanically ventilated with atelectasis after cardiac surgery

description: ABSTRACT The main objective of this study is to associate the healthy area of the lung (evaluated by radiography) with the data of respiratory mechanics in children with atelectasis after cardiac surgery, under mechanical ventilation in the assisted controlled mode. Altogether, 46 children were selected, but 16 were excluded due to irregular respiratory waves or lack of the data on arterial blood gases. A group of 30 children under assisted controlled mode were analyzed, and 10 from this group developed atelectasis. The data were analyzed before and after the onset of atelectasis, and respiratory mechanics was correlated to radiography. We also analyzed the data related to arterial blood gas of these children - who initially had no pulmonary complication - to verify possible changes due to assisted controlled cycles. Atelectasis may modify some parameters of respiratory mechanics. In the association of the healthy area of the lung with the respiratory mechanics, the Spearman correlation results showed statistical significance of the lung area with airway resistance (ρ=−0.648 and p=0.043). Our results show that it is possible to analyze respiratory mechanics waves by selecting controlled cycles in the assisted controlled mode, since we found insignificant changes in potential ionic hydrogen. The analysis of respiratory mechanics allows checking lung function and undesired lung injuries; the analysis of respiratory mechanics can be daily performed in these children to have important information on the pulmonary function. Our research also showed that under the assisted controlled mode is also possible to evaluate respiratory mechanics.

title: Cough peak flow in preschoolers: success rate and test-retest reproducibility

description: ABSTRACT It is important to evaluate lung function in preschoolers. There are few studies related to pulmonary function tests with this part of the population. The purpose of this study was to evaluate the success rate and test-retest reproducibility of the cough peak flow (CPF) in a sample with children between four and six years old. The CPF was tested in 44 healthy children (26 boys, 18 girls), selected according to the ATS-DLD-78-C questionnaire, used to detect the presence of common respiratory diseases or induced by environmental exposure. An expiratory peak flow meter (Piko-I Electronic Peak Flow Meter, Pulmonary Data Services, USA) was used to measure CPF. The success rate was defined as the percentage of children able to perform the test according to the acceptability and reproducibility criteria. To evaluate the test-retest reproducibility, 10 children (according with the sample calculation) were reevaluated after three weeks. The study was approved by the Ethics Research Committee of the Institution. The test-retest reproducibility was evaluated by the paired t-test, considering a significance of p&lt;0.05 and intraclass correlation coefficient (ICC). The results showed a success rate of 91% for CPF, with 80%, 88% and 100% for children with four, five and six years, respectively. Regarding the test-retest reproducibility, there was no significant difference between data of the first assessment and reassessment (p=0.39) and an ICC of 0.84 was observed. These results suggest an elevated success rate in the performance of CPF and an excellent test-retest reproducibility for this variable in healthy preschoolers.

title: Thoracic kyphosis comparison between a patient with chronic obstructive pulmonary disease and a healthy individual by flexicurve method

description: ABSTRACT Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction, air entrapment and pulmonary hyperinflation. These pathophysiological factors can compromise the diaphragmatic mobility, causing deformities in the thoracic cavity and consequently increasing the angle of the thoracic curvature. We compared the angle of the thoracic curvature between COPD patients and healthy individuals by the flexicurve method. Thirty-seven patients with COPD and 37 healthy individuals participated in the study. All subjects performed the following evaluations: anthropometry, spirometry, and measurement of the thoracic curvature angle. The data were analyzed and treated with descriptive analysis such as mean and standard deviation. The Shapiro-Wilk test was used to verify the normality of the data. The Student's t-test was used to compare the thoracic curvature angle of patients with COPD with healthy individuals. The significance level adopted was 5%. The mean age of the COPD group was 65.70±7.91 years, body mass index (BMI) of 26.73±5.34kg/m2, and FEV1(expected %) of 50.65±19.08, showing moderate obstruction degree. Healthy individuals showed an average of 7.27±62.49 years, BMI of 26.97±3.55kg/m² and FEV1(expected %) of 94.05±0 9.44. We did not observe any significant difference between patients with COPD and healthy individuals in the thoracic curvature angle: 56.67±11.31 and 55.42±9.61 degrees, respectively (p=0.61). The flexicurve method proved to be a useful and practical tool for assessing the thoracic kyphosis, and it also identified no difference between the thoracic curvature of COPD patients with moderate obstruction and of healthy individuals.

title: Are thirty minutes of rest between two 6-Minute Walk Tests enough for cardiovascular and symptomatic recovery for patients with chronic obstructive pulmonary disease?

description: ABSTRACT Two 6-Minute Walk Tests (6MWT) are required to evaluate functional capacity of exercise in patients with Chronic Obstructive Pulmonary Disease (COPD). Despite the fact that the American Thoracic Society (ATS) has proposed a one-hour interval between two tests, it is unknown whether a shorter period could be used for the normalization of physiological variables. We aimed to verify that an interval of 30 minutes of rest between two 6MWT is sufficient for cardiovascular and symptomatic variables to return to their basal levels. Two hundred and fifteen patients with COPD (121H, 66±8 years; FEV1: 44 [32-57]% predicted) performed two 6MWT with a thirty-minute interval between them. Before and after the tests, we measured Blood Pressure (BP), Heart Rate (HR), peripheral oxygen saturation (SpO2), degree of dyspnea, and fatigue. Patients walked the longest distance in the second test (6MWT1: 450 [390-500]m vs 6MWT2: 470 [403-515]m; p&lt;0.0001). The initial HR was greater in the second 6MWT (initial HR 6MWT1: 83 [73-91]bpm vs 6MWT2: 83 [75-93]bpm; p=0.001). Dyspnea and fatigue were lower before the second test (initial Borg dyspnea 6MWT1: 0.5 [0-2]m vs 6MWT2: 0 [0-2]; p = 0.0006 and initial Borg fatigue 6MWT1: 0 [0-2]m vs 6MWT2: 0 [0-2]; p = 0.007). There were no differences regarding the BP and the SpO2(p&gt;0.05 for all). Although there are statistically significant differences in initial HR between the first and second test, this finding does not seem to be clinically relevant. Therefore, thirty minutes of rest between two 6MWT are sufficient for cardiovascular and symptomatic recovery in patients with COPD.

title: Influence of age, anthropometric characteristics and body fat distribution in women's thoracic mobility

description: ABSTRACT The accumulation of fat in the chest can contribute to reduced thoracic mobility (TM) with a decrease of lung volumes. TM changes can also occur in aging, due to progressive calcification of joints involved in respiratory movements and reduced intervertebral spaces. The objective of this study was to verify the influence of age, anthropometric characteristics and distribution of body fat on the behavior of women's TM and to check which of these variables is more relevant to the TM. This is a cross-sectional study with 100 women, from 25 to 75 years and body mass index (BMI) between 18.5 and 55kg/m2. Circumferences of neck (NC), waist, hips and waist/hip ratio were measured. TM was assessed by thoracic cirtometry, in axillary and xiphoid levels and, after three measures, the TM was determined by the difference between the highest value obtained in the inspiration and the lowest value at expiration. We used correlation tests and multiple linear regression. Results show, through significant correlations, that with increasing age and obesity, TM decreases. The NC had the greatest influence (16.60%) on TM in axillary level and on BMI in xiphoid level (18.16%). It is concluded that TM is reduced with aging and obesity and that the deposition of fat in the neck and the increase of BMI are the most important factors in the commitment of women's TM.

title: Evaluation of respiratory mechanics in pregnant women

description: ABSTRACT The respiratory function is one of the organic processes most affected by pregnancy, and it can be evaluated by cirtometry and manovacuometry. The changes in thoracic expansibility and respiratory pressures during pregnancy of healthy women were verified. This is a prospective, descriptive and analytic study. Ninety three pregnant women who attended health unities from Ponta Grossa (Brazil) have participated. They were divided in three groups, according to the gestational period: G1 (first trimester), G2 (second trimester) and G3 (third trimester). The following evaluations were performed with each woman: cirtometry in three points and manovacuometry. The thoracic mobility presented reduction while the pregnancy progressed (respiratory coefficient: armpit line - G1&gt;G2&gt;G3, middle line - G1&gt;G2&gt;G3, xiphoid appendix - G1&gt;G2&gt;G3; inspiration-rest: armpit line - G1&gt;G2&gt;G3, middle line - G1&gt;G2&gt;G3, xiphoid appendix - G1&gt;G2&gt;G3; rest-expiration: armpit line - G1&gt;G2&gt;G3, middle line - G1&gt;G2&gt;G3, xiphoid appendix - G1&gt;G2&gt;G3), in all the cases p&lt;0.01. The maximum inspiratory and expiratory pressures decreased from G1 to G2 (p&lt;0.01 in both cases) and to G3 (p&lt;0.01 in both cases). We concluded that the respiratory muscular strength and the thoracic mobility present reduction with pregnancy progression.

title: Functional exercise capacity evaluation in an aquatic environment

description: ABSTRACT The aim of this study was to investigate the correlation between distance achieved and compare the average speed while walking in the six-minute walk test (6MWT) performed on solid ground and in the three-minute walk test in water (3MWT-W) with healthy young individuals, as well as compare physiological (heart rate, oxygen saturation and blood pressure) and symptomatic variables between tests. It is a cross-sectional study, with a sample of 20 healthy young subjects. All patients underwent spirometry, answered a questionnaire on health and physical activity, in addition to performing the 6MWT and 3MWT-W. Statistical analysis used the Shapiro-Wilk test to evaluate normality of the data, the paired Student's t-test and Wilcoxon in the comparisons between the variables and the Pearson correlation coefficient to verify associations. Statistical significance of p &lt; 0.05 was adopted. The mean age was 22 (±2) years, the mean BMI was 23 (±3) kg/m2 and all subjects had normal pulmonary function. The average distance achieved in the 6MWT was of 657 (±43) meters and in the 3MWT-W of 135 (±13) meters. A weak correlation between the 3MWT-W and 6MWT (r=0.35) was found. The speed during the tests showed a statistically significant difference (3MWT-W 0.75±0.07 versus 6MWT 1.85±9.1, p&lt;0.0001). There was no difference in the initial and the final physiological variables between 3MWT-W and 6MWT. The 3MWT-W may be a good tool for evaluation and exercise prescription in the aquatic environment, but showed a weak correlation with the 6MWT and similar physiological strain, though further studies are suggested to confirm this finding.
