sleep test with bad allergy symptoms?

[Merryj]

If you are having horrible allergy symptoms (super stuffy, runny nose, itchy watery eyes) how will that impact a sleepstudy?

[Bugdude]

Are you still able to sleep?

[Merryj]

Yes, I can still sleep but have been waking up during the night and doing a lot of mouth breathing

[Bugdude]

As long as you're able to sustain at least an hour of continuous sleep it should be enough for the study.

[Merryj]

Thanks! Not sure what is blooming right now but it is horrible!

You don't say whether the study is
diagnostic
titration
a split study, in which both are done the same night.

If you go to a study breathing through your mouth, whereas you normally breathe through your nose, most likely:

If it's a diagnostic study, it will still diagnose sleep apnea, but the AHI may not be valid.
If it involves titration, you will not get an accurate determination of the pressure settings you need.

I think using a decongestant nose spray for the study will produce a more representative result.

There are members here who are more expert than I am; perhaps one of them will chime in.
