Bleeding is the
#1 preventable cause of death.
In critical moments, time saves lives.

From the moment a tourniquet goes on, time decides survival. Medical Chrono builds TimeAid TQ, which shows elapsed time through color and touch β with no power at all β restoring the time information missing from every bleeding-control kit.
Why Bleeding Control
Bleeding is the fastest β and most preventable β death.
#1
Leading cause of preventable death after injury
Core premise of the American College of Surgeons (ACS) β hemorrhage

How to Control Bleeding
Anyone can control bleeding β immediately.
Over 5 million people worldwide trained through Stop the Bleed follow one simple idea β Alert, find the Bleeding, and Compress. The tourniquet is the key tool of that final step.
Bleeding
Quickly find the life-threatening source of bleeding.
Compress
Stop it with direct pressure, hemostatic gauze, and a tourniquet.
The Missing Link
After the tourniquet goes on, the most important information disappears.
TCCC and DD Form 1380 require recording the tourniquet application time β it is the basis for reassessment. Yet in darkness, with gloves, under fire, that record is lost while evacuation stretches to 6β7 hours. The missing time becomes lost limbs and lives.
