Capnograms during procedural sedation

    Bhavani Shankar Kodali MD  

Carbon dioxide wave forms may not be as perfect in shape as those obtained in intubated patients (1-4).  However, a change form baseline capnograms during procedural sedation may indicate increased depth of sedation (5-7). In the least, one has to determine the cause of the change in the CO2 waveforms from baseline.  Is it due to sampling problems or increased depth of sedation?
