Not being techy I can't locate the thread where I learnt pulse oximeters cannot tell what oxygen content is in the sp02 rate, but I think I've found an oximeter that does! Then again I'm probably wrong - as usual.
It's the masimo rad 57. Reading the blurb I think it can detect oxygen content as well as rate... Plus other stuff.
The only problem is price! Over £400 refurbished and around £1000 new.
Does anyone have one or used one?
Worth it?
