Continuous Vs Intermittent Non Invasive Blood Pressure Monitoring in Preventing Post Operative Organ Failure

Continuous Vs Intermittent Non Invasive Blood Pressure Monitoring in Preventing Post Operative Organ Failure

Continuous non-invasive arterial pressure monitoring has the potential to decrease the duration of intraoperative hypotension and hypertension compared to conventional intermittent blood pressure monitoring. Chen et al. demonstrated using continuous non-invasive arterial pressure devices for every hour of surgery it is possible to identify an average of 14 minutes of potentially treatable hypotensive and hypertensive time(12). Whether the ability to detect more hypotension events by continuous non-invasive arterial pressure monitoring use can improve patient outcomes, is still an open research question
