Abstract
An apnoea monitor for preventing sudden infant death syndrome (SIDS). The exhaled breath of the infant is collected in a hood. A source of infrared energy emits infrared energy into the hood. So long as the infant is breathing, the carbon dioxide in its breath absorbs a portion of the infrared energy in the hood. Should the infant stop breathing, an infrared detector responds to the resulting increase in infrared energy to activate an alarm so as to enable the attendant personnel to take appropriate life saving action.
