Numerous clinical studies

Intra.Ox Clinical Validation

T.Ox Clinical Validation

Improve Flap Salvage Rates

Flap salvage rates increased from 57.7% to 93.75% ¹
Total flap failure dropped from 9.4% to 1.3% ²
Operative exploration salvage rate improved from 0/4 (0%) to 3/3 (100%) ²

Reduce ICU & Total Patient Length of Stay

Total length of stay decreased from 14.5 days to 10.7 days using T.Ox²
Elimination of ICU stays can save the hospital $1,937 per patient³

Provide Faster Problem Identification

Identifies vascular compromise faster than the implantable Doppler⁴
Provides remote access to view flaps on any web browser and cell phone 24/7

Improve Clinical Confidence

Sensitivity and specificity clinically proven to be very high with no false negatives or false positives in 500+ flaps studied in clinical papers^1,5

T.Ox Data Examples

The T.Ox system provides two critical pieces of data:

A number that reflects real-time oxygen saturation (StO₂), updated every 4 seconds
A graph trending StO₂ over time

The following images demonstrate examples of actual cases highlighting both tissue flaps with and without complications as noted on the T.Ox system.

Unilateral tissue flaps with no complications

Bilateral tissue flaps with no complications
