Capnography monitors track end-tidal carbon dioxide (etCO2), the concentration of carbon dioxide in exhaled air. These waveforms immediately sense changes in O2 levels that may signal respiratory distress. Capnography monitoring has gained popularity in recent years and is considered a standard of care for most outpatient surgery procedures involving moderate or deep sedation. DRE offers stand alone or multi-parameter monitors that can include capnography in dependable cost effective configurations. We make it simple call a monitoring expert to find which monitor best suits your needs.
