I was diagnosed with sleep apnea and began CPAP in December 2018. I did a home study and then an overnight in a sleep center.
I use a Philips Dreamstation with a heated humidifier and tubing, silicone head mask with nasal cushion, and a chin strap. Air setting 6; humidity 3. I use the Philips DreamMapper app to track the AHI’s.
Sleep quality improved dramatically using the CPAP. No snoring or gasping; literally awake feeling rested and refreshed for the first time in my life. AHI’s stay below 5 generally.
In March 2019, I had partial knee replacement surgery and in May 2019, I had shoulder rotator cuff repair surgery. The anesthesia during the surgery and the pain medications after seemed to affect my AHI’s. I think a major factor also is that I have had to sleep on my back since both surgeries, which gives me higher readings than when I sleep on my side. Note: I was told that unless my AHI’s were sustained at 15 or higher during the recovery, I should not worry.
I do believe that medications affect my AHI’s.
I started tracking a correlation. I also noted that what foods I ate from dinner to bedtime also affected my AHI’s. And now I am experimenting with taking some an hour or more before bedtime. Still tracking both meds and foods, as well as the timing.
I take Celebrex and Tylenol now. Have stopped stronger meds.
Sugar in any form or food (even fruit) is the food that seems to most negatively affect my sleep quality.
Update: I checked w my CPAP supplier and Medicare compliance rep and learned that my device can be set for a range of pressures. So I am meeting w my doctor next week to discuss changing my static pressure to a range.
If anyone uses a range, please share your experiences with that.
