摘要
•A physiological marker named oscillatory coupling factor (OCF) was introduced to measure cardiopulmonary coupling.•The obstructive sleep apnea hypopnea syndrome (OSAHS) group had higher OCF than the non-OSAHS group, while cardiovascular disease (CVD) made OCF even higher.•Continuous positive airway pressure (CPAP) could rectify this elevated OCF caused by OSAHS or CVD.•Oscillatory coupling factor has a potential cardiovascular prognostic value for OSAHS patients.
