Eric & Don,
wonder if you could please share some of you knowledge on oximeters?
I've been checking out ebay and there are indeed a lot of oximeters going.
There seems to be quite a few Nellcor n100, n200 & n180's going from $20 - $200 or so. From what I've read the n180 is the newest and smallest so would by my pick out of those 3. Are these any good, ie would they be more accurate compared to the old Ohmeda's?
Also seen some cheap nellcor 3000's, but can't find much info on them. I just found out they do have a serial port. Would these be any better then the n180's ?
The n395 is a bit out of my price range at the moment, or would be my first choice. I will be going for an ear sensor. Even on my friends Ohm-3700, the readings with an ear sensor were way more accurate then the finger sensor. Much less delay but also the %SaO2 didn't seem to read as low a figure at the end of a breathold. ie for me read %55 after a 7.03 static, I still felt I had 10-15 seconds left in me. I also did a 2.35 exhale static (reverse packing) right up to the edge, and it read %41. So if it read too low I don't think it was out by more then %10 or so at a guess.
Thanks a lot in advance,
Wal
