Final answer:
START triage is meant to be completed in under a minute per patient, but practical situations may extend this to 20-30 minutes.
Step-by-step explanation:
The START (Simple Triage and Rapid Treatment) triage system is designed to be a quick method to assess and categorize patients during a mass casualty incident. The objective of START triage is to evaluate each patient efficiently, ideally completing the assessment in less than a minute. However, depending on the complexity of the situation and the resources available, practical triage time per patient could extend to 20-30 minutes in a real-world scenario.
