Sotera Wireless has created a wireless, real-time, vital signs monitoring system.

ViSi Mobile will monitor all of your patient’s core vital signs (blood pressure, heart rate, 3 or 5-lead ECG, SpO2, respiration rate, and skin temperature) “with monitoring accuracy and resolution, typically found in ICUs.”


The system allows your patients to get up and move around without being wired to large, cumbersome monitoring equipment. As long as your patient is within the range of the wireless network, nurses and doctors will be able to monitor the patient’s vital signs. When switching between wireless networks, there may be a 10 to 30 second delay in monitoring.

The data is displayed on a touch screen worn on the patient’s wrist as well as transmitted wirelessly via an 802.11b network, in real time, using existing hospital wireless infrastructure. The system is designed to communicate with desktop PCs, tablet PCs, and other mobile devices. There is also an open API accessible through the ViSi Mobile Appliance (a piece of hardware connected to the network).  Basically, this allows the data to be connected to electronic health records, research applications, or any other database to which a connection might be useful.

For nurses and doctors, ViSi Mobile allows you to access up-to-the-moment vital signs data for any of your patients using the system. The data is more continuous as there is rarely a reason for the patient to disconnect from the system.

Furthermore, the touch screen unit on the patient’s wrist can be set up with a 4 digit security pin to prevent patients from tampering with the equipment. The system makes entire hospitals more agile as well by providing the ability to have ICU quality monitoring of vital signs in any place in the hospital. Not only would this improve the quality of care available in many areas of the hospital, it would also allow hospitals to save money by allowing them to move patients into lower cost beds without interrupting continuous monitoring.

Going forward, Sotera plans to add more functionality to ViSi Mobile. This would include allowing patient monitoring post-discharge, a cuffless non-invasive blood pressure monitor, and tracking patient position and activity. The position and activity monitor would help prevent things like falls and pressure ulcers.
