What channel is designated for multi-patient incident communication (MCI)?

• A. MED channel
• B. NM tac
• C. Repeater radios
• D. VHF channel

Answer: (B)

When managing a multi-patient incident, the crucial practice is to have a single, interoperable channel dedicated to on-scene coordination so all responders can hear and act on incident orders without impacting routine medical talks. In New Mexico, that designated channel for MCI communication is the NM TAC channel. Using this channel keeps incident command, EMS units, fire, and other agencies aligned, enabling rapid callouts for resources, patient distribution decisions, and clear, prioritized updates. It also supports standard terminology and call signs, which helps prevent misunderstandings in chaotic environments.

The medical channel is reserved for patient-care discussions and hospital-related coordination, so it isn’t the centralized channel for incident-wide MCI communication. Repeater radios describe hardware or deployment rather than a specific, standardized MCI channel, and a generic VHF channel isn’t the state-designated MCI coordination channel, which can lead to confusion and interference.
