A CARDIOPULMONARY RESUSCITATION COMPRESSION FORCE MEASUREMENT APPARATUS

摘要

A cardiopulmonary resuscitation (CPR) compression force indicator comprises means (20, 26,′ 28, 30) for monitoring a patient's transthoracic impedance while the patient is being given CPR and generating a corresponding impedance signal, means (32, 34, 36) for processing the impedance signal to provide an ongoing measurement of cardiac haeraodynamic output, means (24) for determining if the measurement falls outside pre-set limits, and means (38) for indicating such determination externally to the person giving the CPR.
