Capnography is also used for breathing retraining on the basis that end tidal volume of CO2 is affected by chronic hyperventilation. Some practitioners of the Buteyko breathing method, or variations thereof, use it as a biofeedback mechanism to slow breathing rate and volume. The health benefits of such a practice are numerous.

Hello! I am a 4th year medical student enrolled in Wikiproject and am going into emergency medicine. I am excited to contribute more information and grow the Capnography page. I would like to expand on the introduction to explain the role of capnography within the normal mechanics of breathing and link that to the wiki page on Respiration (physiology). Further I would like to explain why capnography is distinct from pulse oximetry (oxygenation) with a brief comparison. I would also like to expand the section of medical use to include its role in the Intensive Care Unit to prevent medical complications. — Preceding unsigned comment added by Eliaseid95 (talk • contribs) 17:50, 28 October 2021 (UTC)[reply]

Great work on a difficult subject! I have a few comments that may make it easier your readers.

Introduction: - consider taking out "partial pressure of" in the first sentence (unless it is key to understanding capno). Additionally, "respiratory gases" may be confusing. Consider using "air during inhalation and exhalation." - consider clarifying second sentence. The way it is written is mildly vague. Was it developed for anesthesia and ICU? or are you trying to say these are current uses? - For the third and fourth sentence, consider moving out of the intro and place it before medical uses. Place the second paragraph here and you should be good to go. My reasoning is because the third and fourth sentences explain the graph, but is not necessarily important to introduce to the reader this early on. - - third sentence. consider changing to "The measurement of CO2 in a patient on capnography is usually displayed as a graph of expired and inspired CO2 plotted against time or expired volume." - fourth sentence - "When rebreathing systems are used, capnography can be instrumental in monitoring the patient's respiratory status as the tool can measure end-total CO2, a metric particularly utilized in emergency medicine and anesthesia care."

Medical Use: - great content, but I feel as though it is necessary to go sentence by sentence and ensure the words written mean precisely what you are trying to say. I feel like as a person in medicine, I know what you are trying to say in this section, but to the layperson it is difficult to digest. Although this is a difficult subject, I think word choice will be your best friend.

Applications: - I think it might add to the context of your article if you write examples after your bullets like "confirmation of ETT placement - after intubation, rise in end title CO2 will be detected"

Anesthesia: - it may be important to give context to what anesthesia is such as explaining that when patients undergo general anesthesia, their breathing must be augmented with a ventilator, etc. - it is also important to add references to the first 2 paragraphs. Finding a paper explaining end-title CO2 in anesthesia may work well!

EMS: - lots of great information! This all would be augmented by consistent citations. For example, where did you find the information that paramedics are now beginning to monitor ETO2?

RN: - citations, but other than that, I love the application!

Diagnostic Usage: - consider adding citation if you can find it. Again, I recognize it's a difficult topic with not too much literature, but it would enhance the article if you cited things.

Working Mechanism: - love the explanation! Good citations!

Capnogram Model: - it's nice and comprehensive. Love the equation and explanation of variables.

Hello all,

I've taken the liberty of relabelling Mr Scheidon's diagram.

I'm darned if I can convince wikipedia to upload it though - whoever can perform that, you're welcome to do so. I waive all rights to the image.

A caption like, "A diagram of a capnograph that uses infrared spectroscopy to infer the concentration of carbon dioxide in a gas stream" might be apt.
