Surveillance of infants at risk of apparent life threatening events (ALTE) with the BBA bootee: a wearable multiparameter monitor.
We report on the results of clinical evaluation of a newly developed system for wireless monitoring of pulse oximetry (SpO2), actimetry and position in infants. The sensors, electronics and the power supply were integrated into a specially designed infant shoe named BBA bootee. The comparative data collected in 71 babies yielded a mean (bias +/- SD) value of (-1.2 +/- 1.9) % for SpO2 and (-2 +/- 8) beats per minute for heart rate with regard to reference monitors. A reliable detection of infant's movements and prone position by an integrated 3-axes accelerometer has been validated by video observations. Combining the pulse oximetry and actimetry data, an algorithm is proposed to reduce the oximetry motion artifact and related false alarms. Ergonomics of the sensor-supporting garment is addressed.
