Intermittent desaturations during sleep
#1
Intermittent desaturations during sleep
Just started using a new pulse ox device that vibrates when I desaturate <90. I've been getting 4-5 episodes nightly, moreso in the morning. My AHIs have averaged in the mid 2s. Most prevalent when I lay on my back as opposed to side sleeping. Dead ringer for upper airway collapse I would think. Using a chinstrap but am noticing an increase in dry mouth in the early mornings before waking. Should I bump up my pressure? What else can I do?

RE: Intermittent desaturations during sleep
Let's see your charts including oximetry.

with a dreamstation you have two options

1. more pressure
2. Increase supplemental oxygen
ok there is a third option.
3. Get a BiLevel which will improve your exchange

BUT these are general answers because you have not presented your charts.

RE: Intermittent desaturations during sleep
In part, I think you are falling into the spike trap. Honestly, the spikes, which is what I see, don't matter. What matters is duration. How long were you under 93%, 90%, 88%, 85%, 80%, 75%? These values are there because the top four are used by some doctors as critical values. The lower two are there to indicate the really bad values. Do you have access to these types of values? The longer the duration and the lower the percentage the worse it is.

IMHO turn the alarm off and check your durations. Without question, the alarm is disturbing your sleep.

On your charts turn off the Piechart and calendar and we will see your settings. Take your screenshot with F12 as that will remove them take the shot then restore them after.
