Figure 3. — Working prototype of a home BP telemonitoring system.

Note. BP = blood pressure

Intervention / control patients measures BP at home.

Information is transferred wirelessly from the BP monitor to the smartphone via a Bluetooth transmission protocol.

The smartphone receives the information, organizes, and displays it on the smartphone, and encrypts the information for further transmission over the Internet to a secure server.

If necessary, case managers interact with intervention patients for medication adjustments (up / down) via a web portal using a data transmission protocol known as Health Level 7 (HL-7; www.hl7.org).

Control patients will take their BP recordings to their primary care physician (PCP) or nurse practitioner (NP) during their routine check-up visits.
