ABSTRACT:
The presence and origin of apnea in a newborn subject is detected by separately and concurrently monitoring relative movement of the cranial bones and nasal ventilation. The cranial bones have been found to move with respiration as a function of intrapleural pressure, and monitoring of their movement is accordingly used to generate a signal representative of intrapleural pressure. A nasal cannula, thermistor, thermocouple or CO.sub.2 sensors are employed to concurrently generate a signal representative of tidal volume. Absence of changes in both cranial bone movement and respiratory air flow at the nose is indicative of the presence of central apnea, while absence of nasal air flow accompanied by continuing cranial bone movements is indicative of obstructive apnea. The preferred device for detecting cranial bone movement is a surface inductive plethysmographic transducer, although other suitably sensitive motion detecting devices may be employed.
