Microprocessor-Controlled Memory for Cardiopulmonary Monitoring of High-Risk Infants

A semiconductor memory for delaying waveforms, operated in conjunction with commercially available vital signs monitors and recorders, has been developed to generate a concise record of apneic and bradycardic episodes during long-term monitoring of high-risk infants. The system is useful for quantitating the number, duration and nature of life-threatening episodes without resorting to continuous recording.
