Capnography for Patient Monitoring in Procedural Sedation

The Hong Kong Academy of Medicine released a guideline on procedural sedation (first version in 2009, second version in 2019) to recommend a minimum standard of safety measures when performing conscious (moderate) sedation included the definition, general principles, patient assessment and preparation, staffing, facilities and equipment, monitoring, documentation as well as recovery and discharge. And one of key changes on the second version is highlighted on the use of capnography.

“The provision of capnography for patient monitoring is considered necessary for high-risk patients receiving conscious (moderate) sedation or any deeper level of sedation where sudden unexpected loss of consciousness may occur”

The term capnography refers to the noninvasive measurement of the partial pressure of carbon dioxide (CO2) in exhaled breath expressed as the CO2 concentration over time. The relationship of CO2 concentration to time is graphically represented by the CO2 waveform, or capnogram. Changes in the shape of the capnogram are diagnostic of disease conditions, while changes in end-tidal CO2 (EtCO2), the maximum CO2 concentration at the end of each tidal breath, can be used to assess respiratory condition. It is a reliable indicator to monitor and early detect patient respiratory distress during procedural sedation.

In this talk, we will have a deeper touch, as in a nursing perspective, on the use of capnography for patient monitoring during procedural sedation.
