In terms of qualifying for supplemental oxygen, how many days before discharge should continuous overnight oximetry measures be obtained?
Continuous overnight oximetry measurements should be obtained no more then two days before discharge and in most instances documentation in the medical record must include the O2 saturation value on room air at the time of discharge. Be certain that the conditions (e.g., at rest, during sleep, during exercise with oxygen) under which the measurements are taken are clearly documented within the record as well.
