I consider capnography to be the ultimate safety net for anesthesia providers during MAC or IV sedation cases, but not everyone agrees.

The American Society of Anesthesiologists doesn't mandate the use of capnography for procedures not involving general anesthesia. Here's why the monitoring should be an integral part of patient care during all conscious sedation cases.
