Needs more description Suggestion edit
Most of the article discusses its effectiveness.
The article also needs to say what it is in more detail: Article says it is a valve which "opens". Valves can do many things. Does it stop airflow or reduce it? Is the valve engineered to control the rate of airflow (liters per second) or total volume (liters) of each breath? Does it control air inflow or outflow or both? My guess is that it reduces the maximum rate of inflow, so this reduces oxygen in the lungs (bad) but increases venous blood flow to he heart (good), and effectiveness depends on the good outweighing the bad. I hope that an editor who knows more would be willing to say if it stops? reduces? rate? volume? of inflow? or outflow? and what effects that has on lungs and heart.
Article would also benefit from more coverage of the business side: date of invention, number of suppliers, cost? extent of use? presumably disposable? Numbersinstitute (talk) 15:03, 21 January 2019 (UTC)
