 Although it is generally considered a safe practice, conscious sedation is not entirely risk-free.Ventilation breathing and oxygenation are related but seperate physiological processes. During the process of sedation, clinicians rely on pulse oximetry as a surrogate measure of ventilation. Capnography, a staple gold standard in general anaesthesia, is becoming an increasingly important area of interest for procedural sedation, with studies from other settings suggesting, capnography to be an effective ventilatory monitor for sedated patients.
