The Upper Arm Automatic Digital Blood Pressure Monitor, Model BP Progress (BP3T01-1B) 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 upper arm for a circumference range from 22 to 40cm.

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 a smart phone via Bluetooth. The measurement data can be transferred to a smart phone running the Microlife Connected Health+ mobile software (App).

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
