Quick Answer
When hiking at high elevations, managing wilderness bleeding becomes more critical due to the body's increased blood loss rate at higher altitudes. Elevation helps in managing bleeding by reducing the time it takes to stop the bleeding and promoting clotting. This is crucial in wilderness scenarios where medical help may be hours or days away.
Understanding the Elevation Factor
When you ascend to higher elevations, the atmospheric pressure decreases, which affects the body’s ability to clot blood. At elevations above 8,000 feet (2,438 meters), the blood’s clotting time can increase by up to 30%, making bleeding more challenging to control. This is due to the lower oxygen levels and reduced platelet activity at higher altitudes.
Managing Bleeding at High Elevations
To effectively manage bleeding in a wilderness setting at high elevations, it’s essential to apply pressure firmly and consistently for an extended period. This can be achieved by using a tourniquet or a hemostatic agent like QuikClot. For example, applying 15-20 pounds of pressure to a wound for 10-15 minutes can help promote clotting and stop the bleeding. It’s also crucial to elevate the affected limb above the level of the heart to reduce blood flow to the wound.
Additional Considerations
In addition to applying pressure and using hemostatic agents, it’s essential to assess the wound and the individual’s overall condition. In cases of severe bleeding, it may be necessary to use a tourniquet or apply a pressure dressing to control the bleeding. It’s also crucial to monitor the individual’s vital signs and provide medical attention as soon as possible.
