Tensymetry®

Tensymetry® has been developed using a unique and proprietary combination of biomechanical, electrical and software engineering technologies to enable accurate, continuous, non-invasive measurement of a patient's beat-to-beat blood pressure. Aspects of the technology have also been developed to specifically handle large hemodynamic fluctuations that routinely occur in critical care situations. Solutions to handle external environmental factors, including patient movement and motion that occur frequently in the surgical setting, were also developed to meet the market requirements.

TL-150

The radial artery above the radial styloid process is used as the primary pressure source for the system. A single-use, externally applied, disposable sensor is applied after confirmation by the medical professional that a palpable radial pulse is present. The sensor is then mated to the proprietary Tensys® Bracelet.

After entering the patient's height and weight, no intervention by the user is required to set up the system for blood pressure measurement. Removing the "zero paddle" from the sensor enables the system to automatically compensate for atmospheric pressure, and initiate a scanning operation to define an optimum pressure sensing position over the radial artery. Once the optimum site is located, the system does a dynamic applanation pressure search, slightly compressing the radial artery, to determine the patient's mean arterial pressure. Upon determining the mean pressure, the waveform is "scaled" using the patient's BMI and a proprietary algorithm to determine the diastolic and systolic pressures. The high-fidelity beat-to-beat arterial waveform is then presented on either the TL-150 high-resolution internal display or on the customer's free-standing monitoring system.

Proprietary servo-control algorithms work to enable the TL-150 to automatically and continuously respond to hemodynamic variations and track significant blood pressure changes without user intervention. The user is informed, via appropriate messaging and audible alerts, of any conditions that might affect patient safety such as an Abrupt Loss of Signal.
