Abstract: Disclosed herein is an apparatus and method for the production of ozone gas comprising: a parallel resonance circuit formed by a high voltage transformer and a companion flexible polymeric corona discharge chamber which encloses an electrode and serves as both a passageway and reservoir for oxygen bearing gas, and a fluid counter-electrode, all contained within an appropriate enclosure. Said corona discharge chamber possesses an electrical reactance which can be varied in order to match the electrical reactance of a companion high voltage transformer so that the components resonate, thereby maximizing the transfer of energy to the corona discharge gap. The dwell of corona discharge is further enhanced by an electrostatic potential incorporated across said tube wall (electret effect).

Abstract: A patient monitoring apparatus employs transmitter and receiver units. The transmitter unit is typically mounted on the patient and is equipped with an inflatable blood pressure cuff having an associated acoustic stethoscope pickup piece for detecting the systolic and diastolic pressure related sounds which may be selectively and pneumatically coupled to the transmitter unit for radio broadcast to the receiver unit. The transmitter unit may also be selectively coupled to conventional stethoscope ear pieces and sound pickup pieces which can be either chest, esophagus, or otherwise mounted on the patient to detect the sounds generated by and/or associated with respiratory and cardiac functions. Thus, sounds related to either blood pressure determination or cardiorespirtory ausculation can be detected by the transmitter unit and broadcast to the receiver unit. The receiver unit is typically belt or pocket mounted on the attending anesthetist.
