PulseOx cyclicality - mishfit - 12-29-2020 So, I started using a pulseox (Wellue checkme) during sleep the other night, and in deep sleep, there is a very clear cyclicality to the readings with a frequency of about one minute (I was typically 90-95). Pulse rate appears to be inversely related. I don't understand why this is. It appears to be a real effect since pulse varies as well, but I can't come up with a simple reason for variations over a minute. Is it an artifact of the measurement? if not, can anybody explain? FWIW, I've noticed a similar pattern when I've used oximeters at very high altitude. I always assumed it had something to do with the device. Cheers! RE: PulseOx cyclicality - sheepless - 12-29-2020 not much info to go on. best if you post some OSCAR screenshots of the cpap & oximeter data. meanwhile a stab in the dark: 'cyclicality' sounds similar to 'periodicity'. periodic limb movement can increase respiration rate & I assume affect O2. comparing 02 readings with cpap flow rate might be instructive. RE: PulseOx cyclicality - Crimson Nape - 12-29-2020 You are probably using the Checkme Browser Pro app for your primary analysis. Can you provide any screenshots to demonstrate what you are describing? |
