I am a final year nursing student. I take 02 sats on all my patients as part of routine assessment at the beginning of the shift and then document in their chart the %I've had some nurses tell me they almost never take routine pulseox on patients, they just look at the patient and document their visual findings. They've basically told me that the pulseox machines are finicky and often give wrong % readings anyways. (Just like if the 02 sat says 80% when you put it on the pt but the pt is pink, talking and alert).I was wondering if this is usual practice for other nurses to not take 02 sats on their patients???
