No, the apap algorithm doesn't do anything like a big blast and it doesn't respond that fast.hifiaudio wrote:Does the machine think "he is at a 12 but all of a sudden I think he needs 16" and it just jumps up immediately? So from time to time you may get a blast of largely increased pressure?
It does a hunt and peck thing where it tests the airway and goes up rather slowly over a period of a few minutes. It also doesn't reduce the pressure all that fast once it decides that it doesn't sense a need for more pressure.
RobySue has a good description of how the Respironics algorithm works. Let me see if I can find it.
