Capnography During Deep Sedation with Propofol by Nonanesthesiologists: A Randomized Controlled Trial
Anesth Analg. 2014 Jul;119(1):49-55. doi: 10.1213/ANE.0b013e3182a1f0a2.
From the abstract:
We were unable to confirm an additive role for capnography in preventing hypoxemia during elective nonanesthesiologist-administered propofol (monotherapy) sedation in healthy women in whom supplemental oxygen is not routinely administered. Based on the confidence interval, the benefit of adding capnography is at most an absolute hypoxemia reduction of 7.5%, suggesting that adding it in this practice setting to the routine monitoring strategy does not necessarily improve patient safety in daily practice.
