Q

Revised Trauma Score (RTS)

A

A scoring system used for patients with head trauma.

18
Q

Trajectory

A

The path a projectile takes once it is propelled.

19
Q

Trauma Emergencies

A

Emergencies that are the result of physical forces applied to a patient’s body.

20
Q

Trauma score

A

A score calculated from one to 16, with 16 being the best possible score. It relates to the likelihood of patient survival with the exeption of a severe head injury. It takes into account the Glasgow Coma Scale (GCS) score, respiratory rate, respiratory expansion, systolic blood pressure, and capillary refill.

21
Q

Tympanic membrane

A

The eardrum; a thin, semitransparent membrane in the middle of the ear that transmit sound vibrations to the internal ear by means of auditory ossicles.

22
Q

Work

A

The measure of force over distance.
