Problems leading to interventions by the homecare provider

Event	Intervention homecare provider
90th percentile of pressure>16 cm H₂O or mask leakage of the 95 percentiles>24 L/min or <4 hour of use for three consecutive nights	The homecare provider will call the patient or his/her relatives and will ask about symptoms such as dry mouth, mask issues, discomfort with the device or any other problems. If the only issue is low adherence due to a lack of motivation, the homecare provider will encourage the patient to use PAP. Should there be any other problems, the homecare provider will discuss the case with the PAP coordinator (the same person who sees the patients in the standard arm) and arrange for the patient to talk to or see the PAP coordinator, depending on the patient’s responses and the physiological data obtained. Specific interventions considered standard at the hospital (eg, different mask, chin strap, modifications of pressure settings, modifications of humidifier settings, saline nasal sprays) may be performed to improve compliance.
