What is it indicated for?
The ProBP 2400 is a non-invasive digital blood pressure device using oscillometric technique and an upper-arm blood pressure cuff to measure systolic and diastolic blood pressures, pulse rate and mean arterial pressure (MAP).
The device detects the appearance of irregular heartbeat during measurement, and gives a warning signal with the reading once the irregular heartbeat is detected.
The device can accurately measure blood pressure in pregnant patients including those with known or suspected pre-eclampsia.
