Wireless telemonitoring was used during the habituation phase of continuous positive airway pressure (CPAP) treatment in obstructive sleep apnoea (OSA) patients. Patients were allocated either to the telemonitoring group (n=50) or the usual care group (n=61). Nursing time, patient satisfaction and treatment efficiency and efficacy were compared between the groups at baseline and after one year treatment the CPAP adherence and treatment efficacy were recorded.
