PHOTOPLETHYSMOGRAPHY PULSE OXIMETER FOR CARDIOPULMONARY RESUSCITATION

摘要

A PPG pulse oximeter employing a dual PPG probe including a central PPG sensor and a peripheral PPG sensor connectable in a circuit configuration with a pulse oximeter monitor. In operation, the pulse oximeter monitor controls synchronous generations of a central PPG signal by the central PPG sensor and of a peripheral PPG signal by the peripheral PPG sensor, and also control a CPR pulse detection via the dual PPG probe including a detection of a presence of a spontaneous pulse of the central PPG signal and a detection of a presence of a spontaneous pulse of the peripheral PPG signal.
