How many total tiers are identified for critical care transport?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (B)

Three tiers are identified for critical care transport, providing a graduated system that matches staffing, equipment, and protocols to patient acuity.

The first tier covers transfers that require basic or standard EMS capabilities. It relies on teams equipped for routine monitoring and support, with essential tools like basic patient monitoring, supplemental oxygen, IV access, and standard airway management as needed. This level handles less complex cases where life-sustaining interventions are not continuously required.

The second tier introduces enhanced capabilities for more complex needs. Teams at this level have advanced life support skills and equipment, enabling more detailed monitoring, ventilatory support, and potential administration of certain medications. This tier bridges standard transfers and the most critical scenarios, ensuring patients who need additional support receive it without escalating to the highest level of care.

The third tier is the specialized critical care transport. It fields teams trained and equipped to manage high-acuity patients who require continuous invasive monitoring, advanced ventilator management, and often vasoactive or other critical medications. This tier uses ICU-like equipment and protocols, with personnel capable of handling rapidly changing conditions during transport.

Framing critical care transport in three tiers helps ensure the right resources are used for each patient, optimizing safety, efficiency, and outcomes.
