Impact of a controlled heated breathing tube humidifier on sleep quality during CPAP therapy in a cool sleeping environment . There are conflicting data on the effect of adding a heated humidifier to nasal continuous positive airway pressure ( CPAP ) therapy for patients with obstructive sleep apnoea syndrome ( OSAS ) . The effects of heated humidification on sleep quality and treatment side-effects for patients who prefer a cold bedroom environment have not been studied . A randomised , controlled crossover trial involving 19 patients with a first-ever diagnosis of OSAS measured the effect of conventional heated humidification added to CPAP compared with a controlled heated breathing tube humidifier ( ThermoSmart ( R ) ; Fisher and Paykel Healthcare , Auckland , New Zealand ) on sleep quality . During the night in the sleep laboratory at a mean room temperature of 14 degrees C , less condensation formed with the controlled heated breathing tube humidifier ( 1.9 mL versus 35.3 mL ) in the delivery system . In addition , the total sleep time , time spent in sleep stages 3 and 4 , and rapid eye movement sleep phases were significantly longer and the overall side-effect score was lower than with conventional heated humidification . Patients on nasal continuous positive airway pressure desiring a cool bedroom temperature could benefit from controlled heated breathing tube humidification technology ( with inputs from ambient temperature , set pressure and flow ) .
