Continuous Pulse Oximetry and Capnography Monitoring for Postoperative Respiratory Depression and Adverse Events: A Systematic Review and Meta-analysis

Abstract: The use of CPOX on the surgical ward is associated with significant improvement in the detection of oxygen desaturation versus intermittent nursing spot-checks. There is a trend toward less ICU transfers with CPOX versus standard monitoring. The evidence on whether the detection of oxygen desaturation leads to less rescue team activation and mortality is inconclusive. Capnography provides an early warning of PORD before oxygen desaturation, especially when supplemental oxygen is administered. Improved educatio… Show more

“…Predicting postoperative respiratory depression using noninvasive technology is challenging. Pulse oximetry is an effective monitor to diagnose the hemoglobin‐oxygen saturation levels, although in the presence of supplemental oxygen, this monitor becomes a poor predictor of respiratory depression . Moreover, spot measurements of oximetry are less effective at detecting respiratory depression than continuous oximetry.…”

“…Moreover, spot measurements of oximetry are less effective at detecting respiratory depression than continuous oximetry. In contrast, capnography identifies respiratory depression more consistently than oxygen desaturation by diagnosing apnoeas, independent of the presence of supplemental oxygen . However, sidestream capnography is not widely used outside of critical care settings because of the complexity of the technology, expense, periodic re‐calibration, limited portability, inability to acutely track changes in V T and the need for a sampling line, which is subject to interruptions, sample dilution and disconnects.…”
