Patient Monitoring and Associated Devices during Endoscopic Sedation

Sedation is an essential component for gastrointestinal endoscopy. It allows patients to tolerate unpleasant endoscopic procedures by relieving anxiety, discomfort, or pain. It also reduces patient's risk of physical injury during endoscopic procedures, while providing the endoscopist with an adequate setting for a detailed examination. For the safety during endoscopic sedation, patient monitoring is crucial. Minimal monitoring requirements during endoscopic sedation are periodic assessment of blood pressure and application of continuous pulse oximetry. Continuous electrocardiography is recommended in selected patients with high risk for sedation or have cardiopulmonary diseases. Continuous supplemental oxygen is also recommended for endoscopic sedation. This study describes detailed monitoring and associated devices based on the current guidelines and recommendations from gastrointestinal society of America, Europe, and Korea.
