Others may only require knowledge and preparation as with allergies or motion sickness. A plastic bag tucked into the front of a students shirt or jacket is an alternative to a messy clean up. Others may be sufficient enough to postpone a flight or disqualify one from flying altogether. Next, consider the types of trauma we may encounter as well as the nature of the injuries associated with each. Dr. Walker has provided the following descriptions and some examples.
Blunt trauma consists of a transfer of energy over a comparatively large surface.
For us, it can be suffered from contact of a body part with the ground, striking the frame or even a seatbelt forced into the body as a result of an accident or sudden stop. Sharp trauma is a cutting injury. Being sliced by a knife or a jagged piece of aircraft frame are good examples of sharp trauma. Disruption of skin and blood vessels are the most frequent first aid concerns. Penetrating trauma is a stab type wound.
