Tel-O-Graph GSM

The Tel-O-Graph® GSM is the most innovative and convenient solution available for digital blood pressure adjustment and continuous follow-up of blood pressure readings.​
​ The user normally uses the system to measure their own blood pressure twice or three times daily from the comfort of home. Following measurement, the measured values are encrypted and automatically sent using mobile communication signals from the Tel-O-Graph® GSM to the Hypertension Management Software (HMS CS) or the telemedicine platform, in which it can be managed at the click of a button. The measurement data can also be transferred via GDT or HL-7 to the practice administration software or hospital information system from the HMS CS. The measured values are clearly set out in graphic form, and combined to create automatic reports. This means that the treating doctor or medical professionals have the option of reliably monitoring blood pressure readings with minimal effort at any time, or of adjusting treatment. Measurement data can also be forwarded directly to our customers’ specific in-house databases.​
