Abstract:
1. A method to perform cardiopulmonary resuscitation in a patient in cardiac arrest, the method comprising: providing a valve system comprising a pressure-responsive valve that is configured to be coupled to the patient's airway; providing at least one timing light that is configured to help guide a rescuer in performing a desired compression rate when repetitively compressing the chest; providing instructions to repetitively compress the chest and permit the chest to recoil a rate of about 60 to about 120 times/min by following a cadence of the timing light; providing instructions as to a proper depth for each chest compression; wherein with each compression a volume of respiratory gas is expelled from the lungs; wherein for a plurality of chest recoils, respiratory gases are prevented from returning to the lungs with the valve system such that over successive chest compression/chest recoil cycles there is a successive decrease in respiratory gases within the lungs thereby allowing more blood to enter the thoracic space; and providing instructions to periodically actively expand the lungs with an oxygen-containing gas.
