What this trial studies

This observational study aims to evaluate the effectiveness of the Integrated Pulmonary Index (IPI) in monitoring respiratory complications in patients undergoing gastroscopy. The IPI combines measurements of oxygen saturation, end-tidal carbon dioxide concentration, respiratory rate, and heart rate into a single numerical value to assess respiratory status. Patients will be continuously monitored during sedation to identify any potential respiratory issues that may arise. The study will include patients classified as ASA 1-3 risk scores who are over 18 years old and scheduled for endoscopic procedures.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with ASA 1-3 risk scores who are scheduled for gastroscopy.

Not a fit: Patients requiring mechanical ventilator support or those needing emergency endoscopic interventions will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the safety of sedation practices in endoscopic procedures by improving the monitoring of respiratory complications.

How similar studies have performed: While the use of IPI in monitoring has shown promise, this specific application in gastroscopy is relatively novel and has not been extensively tested in prior studies.
