Abstract
A system including a monitoring device dimensioned for placement on a human. The monitoring device including a plurality of sensors for monitoring a sleep position, a temperature, a carbon dioxide level and a respiration of the human. The system further including a processing unit coupled to the monitoring device, the processing unit capable of processing information from the plurality of sensors and performing an algorithm to determine the presence of a sudden infant death syndrome (SIDS) risk factor based on the information. A method may include monitoring two or more of a sleep position, a respiration, a temperature and a carbon dioxide level of a subject. An algorithm may be automatically performed based on the monitoring, to determine the presence of a SIDS risk factor. The results of the algorithm may be displayed and an alert can be sent to, for example, a mobile device based on the risk level.
