Study Results Demonstrate The T-Line® cNiBP Monitor Provides Clinically Equivalent Blood Pressure Measurements To An In-Dwelling Radial Arterial Catheter

San Diego, CA | February 28, 2006 -- A new study to be published in the February 2006 issue of the Anesthesia and Analgesia shows that the non-invasive Tensys® T-Line®, provides continuous beat-to-beat blood pressure (BP) measurement with comparable accuracy to that of an invasive radial arterial catheter (A-line).

Researchers from Shands University Hospital, at the University of Florida at Gainesville, evaluated the T-Line® device in the operating room with patients undergoing general anesthesia. Systolic, diastolic and mean BP's were compared from the T-Line® and the contra-lateral A-line. The mean errors reported were 1.7 ± 7.0 for systolic, 2.3 ± 6.9 for diastolic and 0.7 ± 5.3 for mean. Likewise, Bland-Altman's test for precision and bias displayed excellent agreement. In addition, the noninvasive arterial waveforms produced from the T-Line® emulated those of the contra-lateral arterial catheters.

"The T-Line® monitor fills an unmet clinical need in our operating rooms. With many patients, continuous BP is desired but an invasive procedure like an A-line is not justified" said Dr. Greg Janelle, Assistant Professor of Anesthesiology at the University of Florida. "Our study shows that the T-Line® provides an accurate non-invasive alternative for beat-to-beat blood pressure management."

"The Shands study reinforces the strong clinical performance of the T-Line® monitor across a broad range of patients" said Chris Jones CEO, Tensys® Medical Inc. "The positive outcomes seen in this study give the anesthesiologist another tool to consider in the clinical management of a patient's blood pressure."

About Tensys® Medical

Tensys® Medical, Inc. is the leader in real-time blood pressure management. The Tensys® T-Line®, the company's lead product, was cleared by the FDA in November 2002 for non-invasive, continuous real-time blood pressure monitoring.

The Tensys® T-Line® measures a patient's blood pressure at the radial artery. It offers anesthesiologists better, more effective control over patient safety during surgery by allowing them to quickly monitor and manage blood pressure variations. The T-Line® provides continuous, real-time data and has clinically equivalent accuracy to that of the arterial line (A-line). The device is based on Tensymetry®, the company's proprietary and patented technology for non-invasively extracting the continuous, beat-to-beat pressure waveform from the radial artery without the use of any external calibration device. The science of Tensymetry® is the result of over eight years of research and development

Tensys® Medical is based in San Diego, California and was founded in November 1995. For more information, please visit the company's Web site at www.tensysmedical.com.
