Which of the following is NOT a trauma guideline?

The physiology of helicopter transport is not considered a trauma guideline. Instead, it relates more to the logistics and operations of emergency medical services and the factors involved in safely transporting patients via helicopter. Trauma guidelines focus on patient assessment and management processes that directly impact the treatment of injuries and the prioritization of care.

In contrast, mechanism of injury assessment, level of consciousness evaluation, and patient history review are all critical components of trauma evaluation. Mechanism of injury assessment helps responders understand the nature and potential severity of injuries based on how they occurred. Level of consciousness evaluation is vital for assessing a patient's neurological status and determining the need for urgent intervention. Patient history review provides important context about the patient's medical background, which can influence treatment decisions.

Thus, while helicopter transport is essential in trauma care, it does not fall under the specific guidelines related to assessing and managing trauma patients.
