Can I use a pulse flow concentrator while sleeping at night?
Most oxygen users find that pulse flow works very well for them during waking hours. However, some oxygen users require at least the option of continuous flow. If you plan to frequently use your portable oxygen concentrator while sleeping, you most likely will need the continuous flow option because people often breath too shallow to trigger the pulse or do not breath through their nose at all while sleeping. Also, if you will need to connect your portable oxygen concentrator to a C-PAP or Bi-PAP machine, you must choose a continuous flow concentrator. You may also need a portable concentrator with continuous flow if you typically breath through your mouth rather than your nose, or if you have high oxygen requirements (5 LPM or greater).
