title: A comparison of pneumogram recordings in infants in the hospital and at home.
abstract: It is not known how environment affects the ventilatory pattern of infants during sleep. Pneumogram recordings of ventilatory pattern and electrocardiograms are performed both in the hospital and at home. However, it is not known if the data obtained in these two settings are comparable. Therefore, 12-hour overnight PNGs were recorded in the hospital and at home within 10 days on 64 infants in three diagnostic categories: apnea of infancy, apnea of prematurity, and siblings of victims of sudden infant death syndrome. Pneumograms were quantitated for total sleep time (TST in minutes), longest apnea (in seconds), periodic breathing, and the total duration of apneas lasting 6 seconds or longer. TST was longer at home for the total group (p less than 0.001) and for the apnea of infancy group (p less than 0.005). No other differences were found between hospital and home recordings for any parameter. There was no difference in the number of abnormal pneumograms recorded in the hospital and at home. Therefore, hospital and home pneumogram recordings are equally sensitive and accurate.
