<p>An apparatus and method are disclosed for monitoring physiological parameters associated with the ventilation of infants during assisted ventilation. The infant is placed in a plethysmograph (10) and various sensors (30, 40, 50) are used to measure flow of gas into and out of the plethysmograph and infant respiration. The outputs of the sensors are supplied to a microcomputer system (130) for processing. A unique calibration system is provided which constantly corrects for changing system parameters such as plethysmographic chamber air leaks, compliance and the like. Additionally, a heating system (60) which exhibits radiant as well as convective heating properties is provided to maintain the infant in a constant temperature environment with a minimal amount of temperature fluctuation. From this data, ventilator breaths are discriminated from infant breaths.</p> |
