Abstract:
1. A carbon dioxide (CO2) monitoring system for use with patients undergoing intubation, cardiopulmonary resuscitation (CPR), or ventilation comprising: a CO2 sensor which receives respiratory gases from a patient and senses the CO2 content of the gases to produce CO2 measurement signals; a recorder which records samples of the CO2 measurement signals; a waveform detector responsive to the CO2 signal samples which identifies characteristics of a CO2 waveform; a monitor operable to identify which of an intubation mode, a CPR mode, and a ventilation mode is the use mode of the monitoring system; a waveform analyzer responsive to identified characteristics of the CO2 waveform and the use mode which analyzes the waveform characteristics in consideration of the use mode; and an alarm which produces an alarm output in response to the indication of an abnormal condition by the waveform analyzer.
