[CPAP] Is it bad to tolerate over 10 in pressure?
#1
I've read everyone has different needs when it comes to pressure, but is it bad to be tolerant to pressures way higher than the average user? Some days ago, I woke up because my machine increased the pressure to 14. 

I was diagnosed severe sleep apnea and my doctor told me I needed 10 of pressure. I though it was ok until I saw most of the people need lower levels. 

Will it be bad in the long term for me? I haven't had a bad night since then and I feel rested, but I am afraid that will cost me my health in the future. 

Thank in advance for your help.

Hi Juango

Your autoset will adjust the pressure to what is needed at a particular time. The required pressure goes up and down depending on a range of factors, but mainly if apneas or hypopneas occur, if you snore or if there are flow restrictions. So setting a single pressure of (say) 10 is a little unrealistic in my view. A lot of doctors do it, and some members here actually prefer a fixed pressure, but I couldn't live with it. My pressure starts at 9.6 and usually goes into the high teens and sometimes low 20s over the course of the night. Your nominal pressure of 10 is not particularly high, and no harm will come if the machine needs to go higher.

There is nothing magic about 10 cm pressure. Many of us use higher pressures. The pressure needed to keep your airway open may change during the night based on sleep position and sleep stage. This is the advantage of the auto CPAP units. Although you were prescribed a pressure of 10 cm, keep in mind that was determined over a very short period of time in a clinical setting. Very few of us use the exact pressure determined from a titration study, and many people on this forum use higher pressures, some up to 25 cm.

Having untreated apnea or even having apnea that is treated but not sufficiently is more of a health hazard than the pressure used to treat the apnea, in my opinion.

Thanks! I feel relieved.

The machine does not make enough pressure to hurt you. I used it to help keep my right lung inflated. The doctor did not like me using the oxygen machine to blow it up. Thank goodness things have improved.

Hi juanjo,
Everyone is different as far as pressure gose, just because others have lower pressure, that doesn't mean that you should. It's great that you are doing so well with your therapy, keep up the good work and don't worry about the pressure hurting you. A pressure of 10CM H2O isn't really that high.
