Investigating Humidifier Issue
#1
Investigating Humidifier Issue
I started using the Philips DreamStation in December 2019.  In the last two months, I have noticed severe dry eyes when waking up and throughout the day.  My research says that my humidifier could help.

However, I'm not sure that my humidifier is working properly.  I fill the reservoir to the max line, set the humidifier level to 5 fixed (not auto), the tube is set to heated on 3, and yet the water in the reservoir will last a week!

Step 1: I first exchanged the water reservoir with a new unit from the manufacturer with no change.
Step 2: I then exchanged the humidifier with a new unit from the manufacturer with no change.
Step 3: I then exchanged the APAP machine with a new unit from the manufacturer with no change.

Troubleshooting with tech support after Step 1 above, the heat plate would get super-hot to the touch when covering the hose outlet with my hand for 60 seconds.  Yet, in normal usage, the water would barely get warm.  Measuring the temperature of the water with a food thermometer showed the water preheated to about 90 degrees F.  The hose gets warm, but then isn't warm in the middle of the night.

Last night was my first night using the new APAP machine in Step 3 above, the water preheated to 104 degrees F, but I woke up with very little water used.  I'm using the Philips DreamWear Nasal under the nose mask.  I get 100% mask fit every night and use the machine 7-8 hours a night.

Attached are three OSCAR screenshots if that is useful.  Why is my humidifier seemingly not working even between multiple machines?

RE: Investigating Humidifier Issue
Hi rreeves,
Welcome to Apnea Board!

I doubt your dry eye issue has anything to do with the humidifier.  

The problem lies with your mask, more specifically the under the nose nasal seal isn't fitting you that well and is leaking air upward and hitting your eyes.  Your leak rate isn't too high, but try to pay attention if air is leaking from the nasal seal.

Either check the mask straps and do some adjusting, or try a different size nasal cushion.  

Believe me, I've had this issue with dry eyes too.  I use a nasal pillow mask, and when the pillows start to get soft, they move around and/or don't seal well.  Any air that leaks will hit my eyes.  Sad

Some other things to consider:

Use eye drops specifically for dry eyes.  I use Systane Eye products.  At night, Systane Dry Eye Ointment is excellent for protecting your eyes.  During the day, if needed, use Systane Gel drops.  

Another thing to try is an Eye Mask.

If you notice, I am focused on your eyes, because from experience, any air hitting the eyes at night will cause dry eyes and can be damaging.  I can't explain why your humidifier water lasts a week.  That's somewhat unusual.

The water in my old Respironics 560 would last about 4 days but now i have to fill my Airsense 10 every two days. Must be a size difference. Miss the longer refills and run out out of water more often now!

RE: Investigating Humidifier Issue
Another two things that can affect how long the water lasts in a humidifier tub is your room humidity level and since we're headed into cooler weather, the heat type you use can be in play as some types tend to dry air out faster or slower. Maybe your room humidity is at such a level that the water isn't used up quickly.

RE: Investigating Humidifier Issue
Our house currently is at 52-53% humidity indoors (thermostat shows our indoor humidity at 53%, and another device I have shows 52% indoors, so those agree with each other and give me confidence they are likely correct).  I don't know if that is "high" or not in this regard...

I live in Colorado - its dry here. If I sleep eight or more hours my water is all used up. If I sleep a bit less, there is sometimes a little water left in the tank. It sounds like you live with much higher humidity. That may be all it is.

Here in AZ. high humidity isn't a problem all that often. Rarely, and I do mean rarely, does my water reservoir run low or out of water. 

It has happened, but I can count those occasions on a couple of fingers. I leave the heated tube option off. Not sure at what level my humidity is set, but it's very low. I'll check tonight just to see for sure. 

The last thing I want to breathe is warm, moist air................... Oh-jeez

I've heard 30-50% humidity is the accepted range. Lower and it's too dry, ending up drying nasal passages etc. And higher means you'll possibly get condensation on the windows in cooler weather.
