Tel-O-Graph BT

The clinically validated blood pressure monitor Tel-O-Graph® BT is the first measurement device on the market that can be used in two areas of application. It can be used for screening in the doctor‘s office and clinic, as well as for telemedical home blood pressure and vascular age measurement.​

In screening scenarios, it provides doctors with the ability to use additional measurement parameters such as central blood pressure and pulse wave speed to quickly and reliably identify patients at elevated risk of cardiovascular disease, and to make better treatment decisions.

Telemedical applications​
In telemedicine applications, after each measurement the patient’s measured values are automatically transmitted by Bluetooth, in encrypted form, from the Tel-O-Graph® BT to the eConnect modem and then the Hypertension Management Software Client Server (HMS CS) or to a telemonitoring platform. This allows doctors and medical professionals to review measured values at any time with minimal effort, or to make adjustments to treatment.
