Low pressure
#1
Anyone have any idea if it's possible to lower the machine lower than the minimum factory setting of 4 pressure? Thanks in advance!

NO, but if you put a bacterialfilter at the end of the hose nearest the mask, you get lower pressure to the mask.

ZZzmeg,
On your other thread, you were giving very good advice on pressure settings, based on the infomation you gave.

CPAP machines cannot go lower than 4, but even on that setting most folk feel as if they are not getting enough air. Almost too hard to breath in or a suffocating feeling.

It would be better if you were using software to monitor your apneas and then determine a pressure setting based on that.
Good luck with your therapy...were here to help.

Thanks for filling out your profile, but now I see you are using nasal pillows. That's good, but especially with nasal pillows, you will have a hard time breathing with a pressure of 4.

I suppose you could also tie a knot in the hose... But I don't think that would be too great of an idea either.

Zzz? You need to focus on:
1.. Do you have apnea?
2.. What pressures are required to abate it.

If the answer to the first question is "No," then you can safely turn off the machine and put it in the closet. Otherwise you need to do whatever is required for you to have a successful outcome using the machine. That means find out what events you are experiencing, and at what pressure they are removed. I don't know what that number will be, but I'm pretty sure it isn't going to be "4."

Most people have a hard enough time breathing I 4cm. I can't imagine going any lower than that. When I used the ramp I had it set at 8, and even that wasn't the most comfortable.

Would like to clarify a bit, do not try this.

a few other things you need to consider. The machine has to blow a certain amount of air (positive air pressure) to keep the air way open when you are inhaling and exhaling. I believe that the studies have shown that 4 is the minimum that would work to keep the airway open.

A second issue is with co2. I believe that a pressure below 4 does not allow for all of the exhaled co2 to be cleared, so that means you start re-breathing the exhaled air, which messes up the o2 and co2 levels in your body.

If you are having a lot of pressure with exhaling, perhaps you need to talk to your doc about testing out bi-pap instead of straight cpap?

FWIW, Devilbiss machines advertise a minimum pressure of 3cm H20.
Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.

There will be minimum pressure level, you cannot lower that level.
