While procedural sedation is usually safe, there can be associated risks.1 For example, respiratory depression is a serious risk that can lead to significant injury or even death. A patient may have apneas or an airway obstruction due to the level of sedation. Also, if a patient is over-sedated, it can lead to slower recovery time.
Supported by clinical papers, anesthesia societies and patient safety councils worldwide, a growing number of anesthesiologists and non-anesthesiologists responsible for providing moderate to deep sedation during procedural sedation are recognizing that using capnography monitoring can help enhance patient safety and improve outcomes.2-7

Clinicians commonly administer procedural sedation to patients for procedures that do not require general anesthesia, but would likely be too uncomfortable for a patient to tolerate while in a conscious state. Some of the healthcare environments that use procedural sedation include:
Multiple factors can contribute to an increased risk of adverse events during procedural sedation including:
Register for a HealthStream®: Capnography with Sedation Education course. Learn how procedural sedation impacts patient safety; the importance of monitoring during procedural sedation and the regulatory agency/guideline recommendations that guide monitoring during these procedures; and how to recognize and respond to abnormal capnography waveforms during a procedure.
Over the last four years, 30 associations and clinical societies worldwide have identified capnography as a tool for managing the risk of respiratory compromise and issued statements and guidelines. Some of these societies have issued guidelines and statements specifically recommending the use of capnography during procedural sedation.
Capnography is a noninvasive, continuous measurement of carbon dioxide during the respiratory cycle as a function of time. It provides critical patient information:
Numerous clinical studies have evaluated the utility of capnography monitoring to improve patient safety by alerting clinicians to indicators of respiratory depression and hypoxemia during procedural sedation.
