case_images: Nocturnal pulse oximetry, TcPCO2 evolution, and sleep stage presentation in PSG, starting at 1 a.m. of the BPAP pressure titration. Hypoventilation was seen (SpO2 between 60 and 98%; PCO2 maximum 75 mmHg) for 4 h during the night, accompanied by sleep structure disruption (recurrent arousal and inability to deep sleep). Sleep stage: W, wake; R, REM stage, N1, NREM stage 1; N2, NREM stage 2; N3, NREM stage 3.

case_images: However, hypoxemia (SpO2 < 90%) and hypercapnia (TcPCO2 > 70 mmHg) still appeared during stage N3 of the first two sleep cycles (Supplementary Figure 1) without much change in ventilator settings.
