Accurate, reliable, noninvasive apnea monitors are in high demand. It has been suggested that acoustic monitoring of the air flow associated with breathing might be preferable to several other currently available techniques used for apnea detection (Stark, 1982). In this study, a monitor was developed and tested based on micro-computer analysis of two signals collected from the chest wall of adult volunteers: (1) breath sounds generated by turbulent air flow through the bronchial airways, and (2) the electrocardiogram. Preliminary trials demonstrated accurate determinations of the heart rate and respiratory rate, as well as reliable detection of apnea simulated by volunteers. Further investigation of this technique is warranted.
