Continuous Non-Invasive Blood Pressure

Continuous non-invasive blood pressure monitoring from finger cuffs is possible with a number of devices. Adoption has been slow due to clinician wariness and validation concerns. This study assessed hypotension less than 65mm mean arterial pressure as compared to 3 minute standard arm cuff measurement in non-cardiac surgery.

“Continuous noninvasive hemodynamic monitoring nearly halved the amount of intraoperative hypotension. Hypotension reduction with continuous monitoring, while statistically significant, is currently of uncertain clinical importance”

There certainly is a wealth of evidence on the harms of even short duration hypotension on the heart and kidneys but whether this mode of monitonring can impact clinically meaningful outcomes remains to be seen.
