Here are two basic questions I have, one about my water tank/humidifier, and the other about "events."
The pattern I've had so far with my water tank is that one morning, the thing will have the same water level it had the night before. Then the next morning it will be empty. It doesn't seem like rocket science to fill and snap the tank in, so I can't imagine I'm doing it wrong (and imagine that if I were, there'd be a warning from the machine). My mask time has been 6-8 hours of use each night. And again, the pattern seems to be 0% water usage, 100%, 0%, etc., on successive nights. Can someone offer thoughts and insight?
And as far as "events:"
- What are they?
- How are they detected?
- Does opening my mouth record as an event?
- My events/hour have been between 3.8 and 4.2, but have increased over time, no night-to-night decrease - should I be concerned?
- One night I took my mask off to use the bathroom and had 3.0 events/hour. This was after six hours. Two hours later, the number had climbed to 4.1. How could such a jump happen; I'd think that the lower number for six hours would be hard to drag up in just two hours.
- Is there a time of night when I'd be most susceptible to events? The above suggests that events increase in the later hours of sleep.
- Many of my longer-tenured friends on CPAP average 0-1 event per hour. Does this come about over time? Is there something I as a user can do to make a drop to this level more likely? For what it's worth, the settings on my machine - pressure and humidity - are both on "auto," and I'd really rather keep them there, than have to master the intricacies of fine-tuning.
