Procedural sedation is a clinical technique that creates a decreased level of awareness for a patient yet maintains protective airway reflexes and adequate spontaneous ventilation. The goals of procedural sedation are to provide analgesia, amnesia, and anxiolysis(reduce anxiety) during a potentially painful or frightening procedure.
CONCLUSIONS: Abnormal ETCO 2 findings were observed with many acute respiratory events. A majority of patients with acute respiratory events had ETCO 2 abnormalities that occurred before oxygen desaturation or observed hypoventilation.

CONCLUSIONS: The results of this controlled effectiveness trial support routine use of microstream capnography to detect alveolar hypoventilation and reduce hypoxemia during procedural sedation in children. In addition, capnography allowed early detection of arterial oxygen desaturation because of alveolar hypoventilation in the presence of supplemental oxygen. The current standard of care for monitoring all patients receiving sedation relies overtly on pulse oximetry, which does not measure ventilation.

CONCLUSION: When propofol is administered for ED deep sedation to facilitate pediatric orthopedic reduction, continuous capnography detects most airway and respiratory events leading to intervention before clinical examination or pulse oximetry.
