We have one of the finger clip ones that you can wear around your neck. So far so good, seems very accurate so far. But again, I work in assisted living and it was purchased by a resident that passed away (we had to take pulse ox q shift), and donated it to us. Calibration however, we haven't had it done yet and my DON says we will have it done q month as soon as she figures out who does it..LOL!
But it is like I always say though...never forget to look and treat patients not the machine! I have had these things go nutty before and saw 99% on someone obviously hypoxic! We also joked around and did one on a smoker...who came up 99% while smoking (pulse ox reads the binding of hemoglobin...not what is bound
...can be CO or CO2, don't forget that...thank you RT's for that lesson).
Now...advise time...I have a resident who always says or insists it needs to go on her thumb, but I get sometimes a 5% difference between thumb and index finger??? I was taught index finger...any preferences (my manual on the small one says index so I go with that...but took some serious conviencing for the resident and family [so basically I did and recorded both for sake of arguement]).
