Why do not we use finger pulse oximeter plethysmograph waveform to monitor the effectiveness of cardiopulmonary resuscitation?

摘要

Both the European Resuscitation Council (ERC) and the American Heart Association (AHA) 2010 guidelines for cardiopulmonary resuscitation (CPR) once again emphasize the need for high quality CPR, including a compression rate of at least 100 min~(-1). Quantitative waveform capnography is recommended as a physiologic monitor of the effectiveness of chest compressions in the new guidelines. Quantitative waveform capnography is not available in most CPR situations and it has to be calibrated, which is time-consuming. Pulse oximetry is much more commonly available. Recent studies show the pulse oximeter plethysmographic waveform can be used as an early indication of changes in the circulation.2 Why do not we use a finger pulse oximeter plethysmograph waveform to monitor effectiveness of resuscitation efforts during CPR?
