Pulse vs continuous: Pulse does not give me a sufficient amount of oxygen. I can sit perfectly still with no movement on pulse, but to do anything else I need continuous flow. I’m on 2L at rest and 8-10L on exertion. The numbers on the POC are settings, not liters. The highest setting on my Inogen 5 puts out less than 2 LPM.

I’ve also been told one should not sleep on a pulse setting as your breathing slows during sleep and it may not be enough to keep you oxygenated.
