Humidification and CPAP systems

Nasal inflammation in sleep apnoea patients using CPAP and effect of heated humidification.

Nasal continuous positive airway pressure (CPAP) can cause undesirable nasal symptoms, such as congestion to obstructive sleep apnoea (OSA) patients, whose symptoms can be attenuated by the addition of heated humidification. However, neither the nature of nasal symptoms nor the effect of heated humidification on nasal pathophysiology and pathology are convincingly known. 20 patients with OSA on...

Use of heated humidification during nasal CPAP titration in obstructive sleep apnoea syndrome.

Nasal symptoms associated with the use of nasal continuous positive airway pressure (nCPAP) in obstructive sleep apnoea (OSA) can adversely impact on patients' tolerance, acceptance and adherence to nCPAP therapy. Regular use of heated humidification is effective in alleviating these symptoms and improve patient comfort. In a randomised, parallel, double-blinded, controlled study, the present a...

Active humidification with Boussignac CPAP: in vitro study of a new method.

OBJECTIVE To carry out an in vitro study of Boussignac CPAP valve performance with a new humidification method, using a heated humidifier. METHODS Two heated humidifiers were evaluated: Fisher & Paykel MR850, and Covidien Kendall Aerodyne 2000. Baseline measurements were taken in all experimental conditions without humidification. The Boussignac valve was adapted to the input of the humidific...

Intelligent CPAP systems: clinical experience.

Nasal continuous positive airway pressure (CPAP) remains the treatment of choice for obstructive sleep apnoea (OSA) syndrome. It is believed to work by pneumatically splinting the upper airway. 2 As the pressure is gradually increased the subject passes through a spectrum of gradually decreasing severity of obstruction. 4 Frankobstructiveapnoeas,hypopnoeas, and desaturation first disappear, the...
