Any thoughts on why my heart rate increases when using CPAP?
Any thoughts on why my heart rate increases when using CPAP?
I am new to using CPAP and have only been using it for 3-4 days so far. Normally I would use a mouth guard that was also made for sleep apnea but I wanted to try switching to CPAP to see if I could get better and more consistent results since I doubt how much the mouth guard actually helps.

Anyhow I also monitor my sleep with an Oura ring and I have noticed my heart rate have increased on the nights I have used the CPAP. My heart rate normally shows that my lowest heart rate for the night is around 60-62 bpm and my average is usually around 65-67 bpm

However on the nights of using the CPAP my lowest is recoded as around 65-67 bpm and average 70bpm.

Also my HRV which is already usually very low at around an average of around 25ms and a max of around 40-45ms has an average of 15ms and a max at around 30ms on the nights of  using the CPAP.

Have anyone else experienced something like this or have any theories on why it is happening?

My thoughts are is that the heart should be more calm and pump less the better and less stressful sleep you have and with less apneas but this show the opposite?

My myAir app show that I have around 5 apnea events per hour. I have ordered a SD card reader so I can import into OSCAR soon.

Is it possible because I am still not used to the CPAP? I am using a nasal pillow mask.

My settings are a min pressure of 7 and a max of 15 and I have EPR set to 2. Also the CPAP is set to autoset with no ramp.

RE: Any thoughts on why my heart rate increases when using CPAP?
Once you have your data imported into OSCAR the answer will be revealed. Considering you're having 5 events per hour and just started treatment leads me to believe there is room for improvement to your CPAP settings for a better therapeutic outcome.
