S9 showing centrals

[stantheman]

Another question. My S9 shows 2 central apneas last night how does the machine know it is a central, I never had them on the sleep study do I need to be worried. How can it tell without a sensor on the head?

It can't. It's just an assumption the machine makes. You will probably start seeing it showing breathing pauses during times when you know you are awake. The data has plenty of room for error. I use it as a guide. What's most important is how you feel each day.

According to your profile display below your message, you don't have an S9.

But if you recently switched to one, do a search under ResMed + Flow(or Forced) Oscillation Technique.

Central apnoea occurs when your body just doesn't want to breath.
The air-space goes from lungs to machine.
The space is larger and more "gooey", therefore has less resistance to pressure.

Obstructive opnoea occurs in the upper airway.
The air-space only goes from gob to machine.
The space is smaller and harder, therefore has higher resistance to pressure.

Well behaved PAPs claim to sense the difference and record it.
I don't know why they bother, because CPAP or APAP won't scare CA.
They haven't got the pressure or pipes to do IPPV (the medical one, not the cable TV one).
They can't defibrilate your diaphram either (the anatomical one, not the other one).

A couple of quick CAs is no big deal.
If you're hyperventilating over it, giving up heroin and binge drinking will help.

Hi
I watched a video on youtube from resmed which explains it very clearly (excuse pun)
