Heated humidification or face mask to prevent upper airway dryness during continuous positive airway pressure therapy.

STUDY OBJECTIVES The objectives of this study were (1) to evaluate the way in which nasal continuous positive airway pressure (CPAP) therapy influences the relative humidity (rH) of inspired air; and (2) to assess the impact on rH of the addition of an integrated heated humidifier or a full face mask to the CPAP circuitry. DESIGN The studies were… CONTINUE READING
