136bpm is fine if the person is, understandably, anxious.
Is a person capable of anxiety if they're missing a fifth of the oxygen they're supposed to have?
IIRC 95% is like "you should probably talk to the doctor" territory
95% is the lower limit of being fine.
80% is "You should go to a hospital. No, I mean by ambulance"
Indeed. "Thanks" to be being a frequent flier in a global company I got Covid already in March 2020 and was constantly checking my oxy values. Never got below 91, but if they had hit 90 I was told to take an ambulance right away.
For reference, I have what my doc calls "emphysema light" and was just in the local doc-in-a-box for my first go-round of COVID. My blood O2 was 97 and I felt short of breath. 80 sounds like I wouldn't be moving under my own power.
