Do you employ the use of noctournal oximetry to assess for a need for supplemental O2 in addition to auto PAP in patients with OSA who have not had an in lab CPAP titration study?
Answer from: at Community Practice
Nocturnal hypoxemia noted on ONO on CPAP doesn't qualify patients for supplemental oxygen. I usually check ONO on CPAP on symptomatic patients who are also on daytime oxygen to assess the adequacy of supplemental oxygen at night.

I do not routinely do so. However, if there is a suspicion for persistent nocturnal hypoxemia due to daytime fatigue or if the patient has a diagnosis of COPD or OHVS and did not for some reason undergo a CPAP titration night, I do perform nocturnal oximetry on Auto-PAP.
