AHI high but no leak, what to do?

[Ecosoph]

Hello,

My AHI for the last week (my first week) was 10, almost all in Apneas (A). Last night it was over 15. The S8 is saying I have little leakage (.2 last night and 0 the night before) and I haven't had much trouble with leaks since the second or third night.

Here's my question. What else would be causing the AHI to stay high if not leaks? Could it be that even small leaks are allowing apnea events? Is it necessarily the case that if I'm not leaking that my pressure is wrong? Or is there something else? Is it possible that I'm leaking more than I thought and the machine is also getting the data wrong? Is it possible that the machine is reading something about my breathing wrong and I'm actually having fewer apneas that it says?

If your leaks are under control ... then it may be possible that your pressure is not high enough to kill your apneas.

What pressure were you titated at?

What pressure is your machine set to?

I was titrated and machine is set at 8.
My AHI for the sleep test was 28, so at least things are better, I just assumed there would be no apneas with the CPAP.

Titrations are a one night snapshot and may not be a true representation of your sleep characteristics ... nonetheless, the titration should be a good starting point.

Sleep position affects the pressure needed to keep the airway open and prevent apneas. Generally, sleeping on back requires more pressure than sleeping on side or stomach.

What you eat/drink and when you eat/drink may also affect the amount of pressure required. Medications ... same. Stress ... same. So lab titrations are not always the final best pressure setting(s) to treat your condition.

You may want to try and increase your pressure by 1 cm and give it a go for a week and document the effects. This therapy takes time to tweak for YOUR optimal treatment.

Good luck.
