Effects of inhaled humidified warm air on nasal patency and nasal symptoms in allergic rhinitis.
The effects of inhaled warm air on nasal patency and on allergic rhinitic symptoms were studied in 102 patients. Treatment consisted of two consecutive 30-minute sessions, during which the patient inhaled saturated, hot (42-44 degrees C) air through the nose. The treatment was repeated 1 week later. During the week following each treatment, every patient recorded his or her subjective response on a daily symptom score card. Nasal patency was determined before and after each treatment by measuring peak nasal inspiratory and expiratory air flow and by measuring the area covered with vapor formed by the exhaled air on a plate. Highly reproducible results were obtained by using these three objective methods. Inhalation of humidified warm air resulted in amelioration of allergic rhinitis symptoms and in increased nasal patency in a high proportion of patients. There were no adverse side effects. This form of therapy seemed effective in the 2-week period in which it was used and would be an additional form of therapy available for those suffering discomfort from allergic rhinitis.
