Interpretation is a big issue. Pulse oximetry is very insensitive to hypoventilation when a patient is on supplemental O2. Also tends to have lots of false alarms--the default limits are not very usable and ideally, people would use patient-specific alarm limits.

Pretty accurate in my experience - the problem may be in how this single value is interpreted in the context of the whole clinical picture:

    How accurate are oximeters? Are the errors big enough to make wrong decisions?
