A conventional humidifier with a reservoir of water for humidification can produce micro-aerosols contaminated with bacteria. The present study was undertaken to determine the clinical efficiency of a membrane humidifier that does not require additional reservoir water. We analyzed relative room air humidity and oxygen levels obtained from 2 pressure-swing adsorption (PSA)-type oxygen concentrators with membrane humidifiers. A significant correlation was found between relative room air humidity and that of oxygen moistened by a membrane humidifier. Several patients with chronic respiratory failure experienced improvements in subjectively reported nasal dryness using an oxygen concentrator with a membrane humidifier. This device avoids the need to change reservoir water, and may improve patient quality of life in the home.
带有用于加湿的水箱的传统加湿器会产生被细菌污染的微气溶胶。本研究旨在确定一种无需额外水箱用水的膜式加湿器的临床效果。我们分析了从2台配备膜式加湿器的变压吸附（PSA）型制氧机获得的相对室内空气湿度和氧气水平。发现相对室内空气湿度与经膜式加湿器加湿的氧气的湿度之间存在显著相关性。几名慢性呼吸衰竭患者使用配备膜式加湿器的制氧机后，主观报告的鼻腔干燥情况有所改善。该设备无需更换水箱用水，可能会改善患者在家中的生活质量。
