92% at 2 liters vs. 95% at 3 liters vs. 97% at 4 liters.

January 15, 2008

This was a question I brought up recently as to whether 96 was better

than 93 or 95 better than 92%.

So, i asked my new pulmonologist today, which would be better:

Now understand this is just one's man opinion but he said there was no

evidence whatsoever to say that we benefitted anymore from 97%

saturation than 92%. The key was not falling below 89% (others say 90%

or 88%). However, he cautioned that some pulse oximeters may have

errors of up to 3% or even 4% so to take that in mind. Therefore if it

were me and 2 liters put me around 90-92%, I'd go to three liters to

compensate for the potential error in the reading.

So, got one question i'd been curious about answered. Don't know if all

pulmonologists would give the same answer or not.
