It’s very hard to free think in stressful situations.
The more you get used to looking around in your environment for items you can co-opt to use in an emergency, the quicker you will be able to improvise if you have to. We set out to use as many items as we could from a typical hotel room to provide emergency casualty care.
It’s always best to have proven, dedicated medical equipment in an emergency, but at some point in your life, you will be someplace where you don’t have that equipment or don’t have enough supplies and equipment. That’s when we improvise. This is one video of a 10-part series.
Again, we prefer to use an off the shelf, commercial tourniquet, but sometimes you don’t have dedicated medical equipment available. In this instance, we cut around the edges of the pillowcase in a U-shape to get enough fabric to make a tourniquet. Although it was lumpy, the casualty said it was the most comfortable of the three tourniquets, and it was proven effective via doppler.
The techniques posted here have some evidence and proof of concept to support their use in an emergency when better materials simply aren’t available.
