Breathing with mask unhooked from the machine - sabaka - 09-29-2021
Hi, I am new to the board. I just got my ResMed 11 and p10 mask a few days ago. I am trying the device by watching TV or reading with the mask on, I had a few hours of sleep with it (with sleeping pills)
What I noticed is that after I put on the mask and before hooking it to the machine, I have hard time breathing through the hose, although the mask hose has an open end. Should I not experience any breathing problems while the mask is not connected to CPAP machine? My machine settings are 6-12. When I connect the mask, I can see the pressure goes up from 4 to 8 while I am laying in bed and reading . Is it normal for the pressure to elevate while not having any apnea ?
Thanks,
Sabaka

Most people disconnect at the mask end of the hose, leaving the hose attached to the CPAP machine.

Except that that isn't an option with the P10. The hose is attached to the frame without a quick disconnect.
When I first picked one up from my local pharmacy to try it out I seem to recall telling the clinician that If I had to get up during the night I would feel like an elephant.
I actually trialled 2 of them, I didn't have any trouble breathing through either one, connected or otherwise, but it seems one of the previous users of the first one I tried did. After noticing that it whistled constantly and leaked like a sieve I took a closer look at it and noticed that someone had taken a pin to the mesh on the front of the frame, and poked a couple of holes in it. Once I noticed that I took it back and they gave me an undamaged one. Not that I used it for long. I ended up swapping it out for the P30i the following day, but that was because the 2 sides of the strap kept slipping together causing the mask to come loose during the night.

There is usually a quick-connect type of fitting at the mask end of the hose (edit: strike that, Neelix pointed out that the P10 has no quick connect.. weird). If you are pulling the hose off of the machine and breathing through the entire hose, you are likely re-breathing some CO2 which would not feel comfortable.
The pressure climbing would be "ramp" which is a gradual increase in pressure at the start of the session, which some people prefer. I keep my ramp off, as I like to have the therapeutic effect from the get-go.

Welcome to Apnea Board!
Awake breathing can be more irregular than asleep breathing. The machine has no idea if you are awake or asleep, and yes... it's normal that the pressure might elevate while awake.
There are other reasons why your pressure could rise. The machines algorithm responds not just to apnea, but also to Flow Limitations, Reras and Leaks. These events don't get added to the AHI score.
The best way to get used to the feel of your mask and the pressure is to wear it for a little while before bed (hooked to machine) while reading or watching TV.

Without the pressure and flow provided by your CPAP machine, the P10 mask would be extremely uncomfortable. The pressure ensures a high vent-rate through the mask and the air you breathe is always fresh, and not air you exhaled in the prior breath. The pressure makes breathing easier. This is why we often refer to very low CPAP pressure as inadequate to avoid a sense of air-starvation. Without positive pressure the mask and tube is under negative pressure making it harder to breathe and you will rebreathe exhaled air. It is not meant to be used in this manner, and by using this mask without the CPAP attached, you are actually not helping yourself adapt to CPAP, but simply making yourself uncomfortable. This works against your objective. I look forward to masking up and feeling my airway expand and making sleep much easier.

I use P10 large, which means the openings are bigger than other sizes and I notice a slight resistance before connecting the 18 inch? Mask hose to the CPAP hose. Try a larger pillow size.
Pressure is driven by apnea, hypopneas, and flow limits on ResMed devices. You need to post your OSCAR charts to get more specific on what is going on.

Let me rephrase then. The P10 has a narrow hose that if I recall correctly is about 20cm long and plugs directly into the air line. This hose cannot be disconnected from the mask as there is no mechanism of any kind to disconnect it, quickly or otherwise.

That's not exactly correct. I have used a P10 mask for 7 years. There's no reason for a quick disconnect. All you need do is pull the mask hose from the machine hose. Takes a second.
