The physiological measures were obtained using the following standardized recording devices: the [Non-Invasive Monitoring Systems (NIMS), Inc], the Alice3 Polysomnogram system (Healthdyne), and a cry recording and analysis system (Cry Research, Inc). To capture the physiological information necessary to meet the study objectives, NICHD, CHIME investigators, and NIMS, Inc. collaborated in the development of a new monitoring technology, which was tested for its potential to detect and record life-threatening cardiorespiratory episodes. The technology incorporated advanced computer capabilities, respiratory inductance plethysmography (RIP), ECG, pulse oximetry, and an accelerometer to detect motion and infant position. In addition to event recording, which captured the physiology for a period before, during, and post-event, the monitor was programmed to store continuous R-R intervals from the ECG, continuous breath-breath intervals, and normative three-minute upochs at hourly intervals. Special software was developed for the scoring of cardiorespiratory episodes on the monitor and polysomnogram recordings (breathing and heart rate parameters) based on a standard scoring procedure developed by the Steering Committee. | |
