All values are reported as Median (IQR) unless specified otherwise. Data from ResMed® devices, Philips Respironics®, and Lowenstein Medical® devices are reported differently by their specific software and are thus shown separately. Unintentional leaks: leaks not related to expiratory valve of mask or circuit. Total leaks: sum of intentional (related to mask expiratory valve) and unintentional leaks. EPAP, Expiratory positive airway pressure; IPAP, Inspiratory positive airway pressure.
