A Low-power wearable acoustic device for accurate invasive arterial pressure monitoring.

ABSTRACT:

Background

Millions of catheters for invasive arterial pressure monitoring are placed annually in intensive care units, emergency rooms, and operating rooms to guide medical treatment decision-making. Accurate assessment of arterial blood pressure requires an IV pole-attached pressure transducer placed at the same height as a reference point on the patient's body, typically, the heart. Every time a patient moves, or the bed is adjusted, a nurse or physician must adjust the height of the pressure transducer. There are no alarms to indicate a discrepancy between the patient and transducer height, leading to inaccurate blood pressure measurements.

Methods

We present a low-power wireless wearable tracking device that uses inaudible acoustic signals emitted from a speaker array t
