I'm working with a group that develops automated blood pressure technology for specific applications. They're looking at developing an automated BP monitor specifically for EMS applications to fill a gap between manual aneroid cuffs and the NIBP on large defib monitors.They're thinking of a...

It's important to remember that BP is an EXTREMELY variable vital sign and by design is very responsive to outside influences (mood, activity, diet, anxiety level...). What floors me sometimes is how clinicians sometimes forget that and treat it as something static like weight for instance...

It is entirely possible, and in fact common in the elderly as rescue99 pointed out, to never reach a phase V (complete disappearance of Korotkoff sounds) when trying to determine diastolic. When this occurs, most clinical groups (American Heart Assoc, British Hypertension Society, etc)...

Marineman has it figured out. An automated BP actually is actually less motion tolerant than a manual reading. Most automated BP technologies are oscillometric, meaning the cuff is the sensor as opposed to a microphone or stethoscope. While most of the NIBP algorithms in high end monitors have...
