1A: For obese patients with sleep-disordered breathing with a high pre-test probability of having OHS, the ATS suggests measuring PaCO2 rather than serum bicarbonate or SpO2 to diagnose OHS. (C, VL)
Patients with a high pre-test probability of having OHS are usually severely obese with typical signs and symptoms of OHS and can be mildly hypoxemic during wake and/or significantly hypoxemic during sleep. This is a recommendation for screening for OHS in patients with sleep-disordered breathing, most typically obstructive sleep apnea (OSA).
