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.
