Contec Pulse Oximeter - CMS50FW or CMS50IW?
#1
Does anyone know what, if any different there are between the CMS50FW & CMS50IW pulse oximeters, if any at all? The websites being written by people with English as a second language make it rather difficult to understand what, if any, is different between the two of them.

Any insight is appreciated.

I think the CMS50iW records the perfusion index (in addition to pulse and SpO2), which is a measure of the quantity of blood flow.

I think if the perfusion is less than about 0.5 or 1.0 then the SpO2 data will be less reliable, so the perfusion data can be used as a sanity check concerning when the SpO2 data is unreliable.


Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.
