Whats the difference between continuous flow and pulse flow oxygen?

Continuous flow oxygen is an uninterrupted supply of oxygen that can be supplied by nose cannula, face mask, or in conjunction with most other breathing devices. Continuous flow oxygen devices are often operated by AC mains supplies and provide reliable oxygen 24 hours a day. In most cases patients are best using this method of oxygen delivery when sleeping or resting. Pulse flow oxygen is delivered on activation of breathing and is commonly known as ‘pulse on demand’. Oxygen is delivered via a nose cannula only, and supplies short doses of oxygen on inhalation. Modern portable concentrators can detect when a patient is going to breathe and release the required amount of oxygen – an incredible piece of technology, I’m sure you’ll agree. These devices are often very lightweight and can supply oxygen over a long period of time, making them ideal for day-to-day activities and for travelling.
