What sign should be addressed first in a traumatic cardiac arrest during triage?

In traumatic cardiac arrest, the absence of a palpable pulse is a critical sign that indicates the need for immediate intervention. When there is no detectable pulse, it signifies that the heart is not effectively pumping blood, which leads to inadequate circulation and oxygen delivery to vital organs. This represents a highly emergent situation in which time is of the essence.

Addressing the absence of a palpable pulse prioritizes the patient's immediate survival, as effective cardiopulmonary resuscitation (CPR) and advanced life support measures are essential to attempt to restore circulation and prevent irreversible damage to the brain and other vital organs. Recognizing this sign allows healthcare providers to initiate the necessary life-saving interventions promptly.

While visible injuries and the respiratory rate are important factors to assess during triage, they do not take precedence over the absence of a pulse in the context of cardiac arrest. In such cases, addressing cardiac function and perfusion must come first.
