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?
