ABSTRACT:
An emergency life support system including a patient ventilator for mechanical breathing assistance; a capnograph to monitor CO2for ventilation effectiveness; a pulse oximeter for measuring blood stream oxygen saturation; a carbon dioxide sensor; an electrocardiograph (ECG) to monitor cardiac performance; an infusion pump; and alarms and a data recorder. The preferred embodiment uses an oxygen generator to deliver oxygen, to generate electric power to run the ventilation system, and to warm IV fluids and resuscitated air. The generator has electronically controlled valves and a modified valve system that offers the ability to select the oxygen concentration in the air delivered to the patient.
