Talk:Mechanical ventilation

message: victims can no longer breathe easily or cough to clear their lungs of dangerous mucus.  Typically, these patients get a tracheotomy - a tube inserted through a hole drilled in the throat so air can be pumped in and secretions suctioned out.  The opening is vulnerable to lethal bacteria  and patients routinely get pneumonia.  Often, they can't speak.  Constant care to keep the tubes open forces many into nursing homes.
There is a noninvasive alternative that few doctors offer, contends Dr. John Bach of the University of Medicine and Dentistry of New Jersey.  The key is a 1952 machine called the Cof-flator that, when held to the mouth, sucks air from the bronchial tubes to induce a cough that  patients can't force unaided.
Once patients can clear their lungs, they can breathe with standard oxygen masks or with an easily learned inhaling technique
I wonder where this can be inserted into this article...

This process usually also stabilizes patients' heart rhythyms, so in many cases, a ventilator is sufficient to keep a patient with a severely damaged body alive.
This is, at least, very vague. Perhaps this sentence refers to the life-saving properties of ventilation in severe hypoxemic states? Anyway, needs to be clarified before it can go into the introduction. Kosebamse 07:57, 9 Oct 2003 (UTC)

message: Have just put  a wee bit about Vesalius and his method of inflating (animal lungs) in the history. On re-reading I feel that the history is focused on the mechanical aspects (i.e. machine-based) rather than the ventilation bit. I was going to add a bit about Lassen's work in Copenhagen during the polio epidemic which involved intubating patients due to the lack of iron lungs. Do people think this would be appropriate here? Anyone bothered if I re-jig the history bit to add a bit on manual (as opposed to mechanical) ventilation?Mmoneypenny 18:22, 16 September 2006 (UTC)

thread_title: Survey

message: IMO, mechanical refers to the use of electrical, automated machines to provide assistance to breathing, whereas artificial ventilation is an umbrella term that includes both mechanical as well as hand-assisted ventilation. At least in the emedicine.com website listed at the end, mechanical ventilation does not include hand-assisted ventilation. Hand assisted, CPAP, BIPAP are categorized as noninvasive ventilation while mechanical ventilation refers to invasive ventilation requiring an ET or trach tubes. 
And in addition, I don't think hand ventilation is mechanical at all in any sense Andrewr47 01:21, 11 January 2007 (UTC)
thread_title:  Mechanical vs artificial 

message: This heading, IMHO, may lead to a description of how ventilators are set in any contributors own ICU, and also addresses more controversial issues of management a little too early in the article. At the moment, the article has a definate slant to adult ICU, and the comment about Assist control being the primary setting on a ventilator is certainly not true for many neonatal intensive care units, transport services (where the servos required fo AC ventilators may be too heavy and unweildy) and even those in countries with less wealth (these ventilators are up to 10 times the price of IMV). The article may be more informative if the heading modes of ventilation were to include AC ventilation, with a comment about its common use in adult ICU, rather than under this heading. would ventilator settings (as this is a more technical and controversial aspect of mechanical ventilation) be better towards the end of the article? Whyso 14:57, 11 February 2007 (UTC)
replies: text: Agree with adult slant point.  Removed following from HFOV description: "Mean airway pressure in HFOV is most often significantly higher than pressures provided with conventional PEEP (30-40 cmH2O or higher) and is usually started at ~10 cmH2O above the MAP measured during conventional ventilation."  In infants the MAP is generally set at 1-2 cmH2O higher than with conventional. If comment is correct for adults, replace with qualification. Hallbrianh 19:53, 14 March 2007 (UTC)

replies: text: You are correct that CMV is frequently used in anesthesia.  I added this comment.  Have been looking at this entire page for a while.  The page needed significant reorganization as it had an almost single focus on assist control use in adults from a somewhat one-sided point of view, together with a hodge podge listing of other modes without unifying explanation.  Attempted to reorganize into more logical order and balance out presentation of modes and treatment decisions.  Would welcome other suggestions.

thread_title:  Copy edit: head section 

message: I've come across an interesting and relatively new (2006) reference which asserts Galen was the first to describe mechanical ventilation, not Vesalius.
Galen is the first to have described ventilating and animal: "If you take a dead animal and blow air through its larynx [through a reed], you will fill its bronchi and watch its lungs attain the greatest distention." He was fascinated by the question of how air could be drawn into the heart. Unfortunately for Galen, this was a question that could not be solved before the development of the microscope and the concept of diffusion.  Also unfortunate for Galen was his failure to appreciate how ventilating the lungs could help him in his vivisection work. Galen operated on many living animals but his studies on the function of the heart were limited by the risk of pneumothorax. Opening the thoracic cavity almost certainly resulted in the death of the animal. It was over a thousand years later that Vasalius realized that ventilation could protect animals from pneumothorax. The beating heart would almost stop when Vesalius opened the chest cavity, and the lungs would collapse but could be restarted by inflating the lungs through a reed tied into the trachea. It is unclear whether Vesalius learned this procedure from others or developed the idea directly from Galen's work. A fascinating coincidence is that Paracelsus, a contemporary of Vesalius, is reported to have used a similar technique around 1530 in attempting to resuscitate a human. Did Paracelsus adapt Vesalius's research efforts, or vice versa?"

Je.rrt (talk) 14:23, 14 September 2011 (UTC)
thread_title:  Adaptive Support Ventilation 

message: I noticed that there were a few orphan sections in the article that seemed to be left over from newer edits to the the ventilator mode section. Other parts seemed either factually incorrect, didn't seem to fit, or were redundant considering the more lengthy discussion below regarding ventilator modes. I reworked the breath initiation/termination section into information regarding the phases of breath delivery, but I'm not even sure that it should be included in this main article.
I kept the following in the article, but it doesn't seem to fit where it is, and may even be redundant.
*Volume ventilation — A predetermined tidal volume (Vt) is set by the clinician, and is delivered to the patient every time a breath is triggered.  For example, if the tidal volume is set at 500ml, the ventilator will continue inspiration until 500ml have been delivered to the patient. Upon completion of inspiration, the ventilator will cycle to exhalation. The amount of pressure necessary to deliver the tidal volume is determined by the resistance and compliance of the patient and ventilator circuit, and may vary from breath to breath. Inspiratory pressures must be closely monitored to prevent barotrauma.
*Pressure ventilation — A predetermined peak inspiratory pressure (PIP) is set by the clinician and delivered to the patient throughout the set inspiratory time (Ti) The tidal volume delivered to the patient is determined by the resistance and compliance of the patient and circuit, and may vary from breath to breath. Inspiratory volumes must be closely monitored to prevent hypoventilation or hyperventilation. 
Several manufactures have incorporated features from both of these modes in an attempt to accommodate patients needs.
These modes are flow-variable, volume-targeted, pressure-regulated, time-limited modes (for example, pressure regulated volume control — PRVC). This means that instead of providing an exact tidal volume each breath, a target volume is set and the ventilator will vary the inspiratory flow at each breath to achieve the target volume at the lowest possible peak pressure. The inspiratory time (Ti) limits the length of the inspiratory cycle and therefore the I:E ratio. Pressure regulated modes such as PRVC, Auto-flow (Draeger)or Average Volume Assured Pressure Support (AVAPS) from Philips can most easily be thought of as turning a volume mode into a pressure mode with the added benefit of maintaining more control over tidal volume than with strictly pressure-control.
I removed this portion as it didn't seem to fit with the addition of other sections.
--Ventilation process in conventional mechanical ventilation--
The three traditional categories of ventilators are listed below. As microprocessor technology is incorporated into ventilator design, the distinction among these types has become less clear as ventilators may use combinations of all of these modes as well as flow-sensing, which controls the ventilator breath based on the flow-rate of gas versus a specific volume, pressure, or time.

replies: text: No, in this case "acute on chronic" indicates a patient who has a chronic disease (like emphysema) but then develops an acute illness (like influenza) on top of their usual problems.

Evaluate the drafted changes
Lead:
The lead has been updated to reflect the contents of the article. The introductory sentence does a good job of defining mechanical ventilation and its role in medicine. The lead provides an overview of most sections. It does not touch on the history or risks/complications, so maybe an additional sentence or phrase could be added to encompass those. The lead does not include information that is not present in the article. The lead has been improved to make it more relevant to the article and to describe the topic in a more accessible way.
Content:
Relevant information has been added to the "Uses" and "Risks and complications" sections. The "Mechanism" sections has been cleaned up to remove information that goes into too much depth. Additionally, the "History" section has been expanded upon greatly. All of the updates to the content are relevant to the topic and improve the overall readability of the page. Most of the citations are from the 2000's and seem up-to-date. The page appears to be fairly comprehensive.
Tone and balance:
The content added is neutral without biases towards any particular position. The article is neutral without any overrepresentation or underrepresentation of groups. For example, information is provided on infants and adults, and the use of certain medications such as opioids in both populations is presented.The added content is informative but not persuasive in favor of any particular position.
Sources and references:
Most of the new content is appropriately cited. There are some areas where additional citations may be appropriate. For example, in the "History section", the third paragraph "With increased... used in the ICU" does not have any citation. Even if the same citation was used as the previous paragraph, it might be worthwhile to cite it again just to make the source of the information clear. The content reflects the cited sources. For the most part, sources are current. The links appear to work.
Organization:
The content that has been added is concise and readable. Added content does not have any obvious grammatical or spelling errors. The organization of the page has been improved and the content has been added to relevant sections.
Images and media:
The article includes multiple images that make it easier to visualize certain aspects of the topic. Most of the images are well-captioned. Some are more descriptive than others. The images appear to be compliant with copyright regulations.
The images are laid out alongside the relevant sections.
Overall impressions:
The information added is of good quality and the reorganization of the article has increased its accessibility to readers without much background knowledge in this subject. The removal of information that is too in-depth and the expansion of certain areas of the article have definitely improved the quality of the page. The added content makes it easier to learn about the history of mechanical ventilation and also makes the content on mechanism, uses, and risks more accessible to a reader without a good understanding of the subject. Some areas of the article (particularly "Negative pressure machines" and "Types of ventilators") have been marked as needing citations. Perhaps in future edits, those areas could be improved to ensure that the information is accurate and backed by reliable sources.Vs2022 (talk) 19:30, 15 November 2021 (UTC)
