An apparatus for cardiopulmonary resuscitation with feedback of measurements of the pulse, and / or of the oxygen content of the blood

摘要

The apparatus has a pulse sensor measuring a pulse rate of a victim and a SpO2 sensor measuring blood oxygenation. Electronics processes outputs of the sensors and determines actions of a rescuer who performs cardio-pulmonary resuscitation (CPR). A prompting device conveys the actions to the rescuer. The electronics provides a prompt that instructs the rescuer to release from a chest.
