Passive Measurement Technique Transforms Vital Signs Monitoring

An innovative continuous noninvasive blood pressure (cNIBP) device aids clinicians in continuously monitoring all patient vital signs, without the use of a catheter or blood pressure cuff.

The ViSi Mobile wireless patient monitoring system is a wrist-worn monitor that measures all core patient vital signs, including cNIBP, beat-to-beat blood pressure, pulse rate, electrocardiogram (ECG), blood oxygenation level, respiration rate, and skin temperature. Wireless technology transmits the vital sign data, enabling clinicians to monitor measurements on remote viewing or notification devices. The system incorporates several safety features, including an advanced alarm management system to notify clinicians of unfavorable changes in a patient’s condition, enabling early intervention if needed.

In addition to a color touch-screen display on the device, platforms such as desktop or tablet PCs can be utilized as remote viewing and notification devices. ViSi Mobile is able to leverage the existing hospital WiFi infrastructure, and is designed to provide information output in electronic form, as well as printouts. Studies comparing clinically validated cNIBP technology with invasive arterial line procedures have demonstrated a bias of less than 5 mmHg. The ViSi Mobile wireless patient monitoring system is a product of Sotera Wireless (San Diego, CA, USA), and has been approved by the US Food and Drug Administration (FDA).

“Blood pressure is one of the most important vital signs, and yet it is considerably undervalued, largely because most clinicians are limited to periodic cuff-based measurements,” said Tom Watlington, CEO of Sotera. “By providing data collected around the clock without disrupting a patient’s sleep, we believe the ViSi Mobile System with cNIBP will help improve diagnosis and management of hypertension, saving lives and dollars.”
