Abstract
The cardiac pulmonary resuscitator improved patient valve has a top and bottom portion joined together forming a cylindrical housing. A diaphragm is mounted between the housing top and bottom portions through which air passes to and from the patient. A rigid tubular port integral with the top portion has a first opening outside the housing and a second opening inside the top portion. A pair of stops on each side of the second opening prevents the diaphragm from blocking air into the rigid tubular port so that some air to and from the patient flows through the rigid tubular port to an air sampling device for making a reading.
