Quick Answer
When applying a tourniquet under pressure, prioritize a swift and decisive action, identifying the correct location of the bleeding, and using a windlass or strap to tighten the device while maintaining a clear path for circulation checks. Ensure the tourniquet is placed at least two fingers below the injury and is tightened in 2-3 seconds to minimize unnecessary bleeding.
Pre-Application Checks
Before applying a tourniquet, quickly assess the situation and the individual’s condition. Identify the type and severity of the injury, and check for any other life-threatening conditions that may require immediate attention. Next, locate a suitable surface to place the individual and have a secondary person assist with the tourniquet application.
Tourniquet Application Techniques
To apply a tourniquet, place the device on the affected limb, at least two fingers below the injury site. Use a windlass or strap to tighten the device in a swift motion, aiming to achieve pressure that stops bleeding in 2-3 seconds. The tourniquet should be tightened to a pressure of around 180-200 mmHg to effectively control bleeding while minimizing the risk of ischemia.
Circulation Checks and Monitoring
After applying the tourniquet, immediately check the affected limb’s circulation by monitoring for a pulse, capillary refill, or changes in skin color and temperature. If the limb shows signs of ischemia, such as a lack of pulse or severe pallor, the tourniquet should be loosened to improve blood flow. Repeat circulation checks every 15-20 minutes to ensure the tourniquet is not causing unnecessary harm.
