A blue alert is typically activated when there is a significant concern for severe hemorrhage or compromised circulation following a traumatic event. In the context of pulse findings, the presence or absence of pulses indicates the adequacy of blood flow and perfusion to the body.

When assessing the carotid, radial, and pedal pulses, a scenario where only the carotid is palpable, while both the radial and pedal pulses are absent, raises a serious red flag. The carotid pulse is a central pulse that indicates that there is still some perfusion to the brain. However, the absence of both the radial and pedal pulses suggests that the blood flow to the extremities is critically compromised. This may indicate either severe blood loss or shock, which are life-threatening conditions. Therefore, this assessment warrants a blue alert as it signifies that the patient may be in imminent need of advanced medical intervention.

Other pulse combinations, such as having all pulses palpable or just the radial and pedal pulses palpable, do not indicate the same level of emergency. All pulses being palpable with normal pressure reflects stable circulation, while only the radial and pedal pulses being present suggests that the brain may still be adequately perfused due to the presence of the carotid pulse.
