This is a single-site observational, before/after cohort study comparing intermittent blood pressure measurement using to continuous noninvasive blood pressure measurement. The study is designed to determine the impact of the use of continuous noninvasive blood pressure monitoring on the incidence of hypotension in high-risk patients undergoing sedation for upper or lower endoscopic procedures.
This is a single-site observational, before/after cohort study comparing intermittent blood pressure measurement using an oscillometric arm cuff to continuous noninvasive blood pressure measurement on the incidence of hypotension in high-risk patients undergoing sedation for upper or lower endoscopic procedures.
The primary aim is to determine the impact of the use of continuous noninvasive blood pressure monitoring on the incidence of hypotension. The secondary aims are to evaluate the impact of continuous blood pressure monitoring on total IV fluid administered, total vasopressor administered, intra-operative depth of sedation, post-operative nausea and vomiting (PONV), and the time to discharge readiness.

Start is estimated for Nov 2026; primary completion for Dec 2027, 13 months later.
Of 146 non-industry observational studies under Hypotension, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 25. This study's planned 13 months is close to that.
Counting every sponsor, half of 151 studies reached it within 11 months; a quarter within 5 and three quarters within 24.
