Active heated humidification improves the side-effects of CPAP therapy for patients with sleep-breathing disorder (SAS) in the upper airways.In a cool ambience temperature, however, condensation will form and the patients feel disturbed in their sleep.The object of this study was to examine the effects of condensation on sleep quality during continuous CPAP. Furthermore, a comparison of sleep quality achieved with an active heating breathing tube versus conventional heated humidification was intended to be gained in a prospectively random study.
19 patients with a first diagnosis of obstructive sleep apnoea syndrome, median age 55.2 (+/- 10.4) years, median BMI 32.8 (+/- 6.3) kg/m2 and median ESS score 10.8 (+/- 5.0) were treated with CPAP (HC 602, Fisher & Paykel) with conventional heated humidification (integrated humidifier and tube heater turned off, humidification via HC100, temperature 32°C) and on another night with an active heated breathing tube (level 8, heating humidifier 32°C) in the sleep lab.
The results of the poysomnography data.
If condensation forms in the CPAP tubing system, sleep quality is considerably reduced. This can be eliminated almost entirely by a heated breathing tube.
We suggest that patients needing active heated humidification during CPAP, who wish to sleep in a cold bedroom ambience, should use a system with a heated breathing tube.
