Abstract
An infant warming and sensor mat for keeping a baby warm and monitoring the baby's haemoglobin oxygen saturation level (SaO2) and heart rate. The mat preferably comprises a bottom layer of compressible padding material, a sensor layer comprising a plurality of light sources and light detectors, a cover layer having multiple openings, and an air layer between the sensor layer and cover layer. Warm air supplied to the air layer escapes through the openings in the cover to warm the baby. The light sources shine light of an appropriate wavelength onto the baby through the openings in the cover, and the light detectors sense the amount of light reflected back from the baby, which is indicative of SaO2 level. Heart rate is also determined from the resulting periodic signal.
