Abstract
Adverse respiratory and gasometrical effects have been described in patients with acute respiratory failure ARF undergoing noninvasive ventilation NIV with standard heat and moisture exchangers HME We decided to evaluate respiratory parameters and arterial blood gases ABG of patients during NIV with small dead space HME compared with heated humidifier HHThe effects of HME and HH on respiratory rate minute ventilation EtCO2 oxygen saturation airway occlusion pressure at 01 s ABG and comfort perception were compared during two randomly determined NIV periods of 30 min The relative impact of HME and HH on these parameters was successively compared with or without addition of a flex tube 40 and 10 patients respectively
