T-Stat For Reconstructive Free Flap Monitoring

When you need a reliable and accurate
bedside monitor, choose T-Stat white light
technology for real-time tissue perfusion.

The T-Stat continuously monitors St02% at the micro-vascular level, reading only 2-3 millimeters deep within the capillary bed, providing a better understanding of how much oxygen is reaching the flap.

The sensitively of T-Stat can detect issues hours prior to flap loss any earlier than any other means of detection. The ability to detect potential complications earlier can vastly change the outcome of the flap.


No other device is as sensitive to changes in perfusion.  With T-Stat you can improve patient outcome and satisfaction, lower costs, while avoiding
potential liability.


Non-invasive Sensors available in multiple sizes.
Sensors come in two surface sensor sizes:

1cm and 2.5cm and buccal.


Multiple sensor sizes allow surgeons to utilize T-Stat on even the smallest of exposed skin paddles on a buried flap, a larger DIEP flap, or a even complicated intraoral case.

Hemoglobin Monitoring
Additional monitoring of Hemoglobin allows the surgeon to decipher arterial vs. venous occlusions.

Venous vs. arterial – what is the difference? When we study venous vs. arterial occlusion, it is imperative that we evaluate both StO2 and Hmg.


Here (see chart) we can see that an arterial occlusion (simulated by clamping the artery before lifting the flap) shows a rapid drop in both StO2 and Hmg over the course of minutes.

A venous occlusion (shown on the right) which is often more difficult to detect, displays a drop in StO2% and an INCREASE in Hmg. This is relative to the amount of blood that is pooling within the flap.

Remote Access with OnCall monitoring.  Users have the ability to log onto oncall.com for private and secure data monitoring. A web-based system allows easy access from any wifi-enabled or cellular device to check immediate results for both St02% and Hemoglobin. Users have access to an unlimited number of T-Stats that are easily added and removed to one’s account.

SD of +/-2 with T-Stat white light technology T-Stat uses broad-band white light to evaluate up to 260 wavelengths, including Hemoglobin in its 5 natural states.  T-Stat then provides a saturation value that correlates with mixed venous saturation. With a SD of only +/-2 this accuracy gives the surgeon a clear understanding of what is actually occurring at the capillary level.
