What is the difference between continuous flow and pulse dose delivery?

For continuous flow, think of it like a water fountain: If an individual stands in front of a water fountain flowing at 1 liter per minute, they don’t actually drink one full liter of water. The amount of water a person drinks is a product of the number of sips and the size of the sip. The rest of the water is wasted. The same applies to continuous flow oxygen.

Pulse Dose is more sophisticated. Pulse Dose mechanisms are more sensitive, utilizing an oxygen conserver and other technology to deliver oxygen based on breathing rates and other factors. Pulse dose is more akin to a glass of water with a straw than a fountain; the intake will be based purely on the amount and intensity of sips.
