What is it indicated for?
The Microlife Wrist Watch Blood Pressure Monitor, Model BP3NU1-4X is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a non-invasive oscillometric technique in which an inflatable cuff is wrapped around the wrist.
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 be used in connection with your personal computer (PC) running the Microlife Blood Pressure Analyzer (BPA) software. The memory data can be transferred to the PC by connecting the monitor via cable with the PC.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
