What should be done for a casualty with blast or penetrating trauma who has no pulse, respirations, or signs of life?

For a casualty with blast or penetrating trauma who exhibits no pulse, respirations, or any signs of life, the most appropriate course of action is to refrain from initiating resuscitation attempts. In cases where there are clear indications of death—such as the absence of respiratory and cardiac function—the likelihood of successful resuscitation is extremely low.

This aligns with the principles of Tactical Combat Casualty Care, which emphasize the importance of prioritizing resources and efforts where they can be most effective. In a chaotic or tactical environment, expending time and effort on a casualty who shows no signs of life diverts attention from other potential survivors who may still benefit from medical intervention.

Also, considering the nature of blast or penetrating injuries, the chances of survival decrease significantly if the casualty is not responding to basic life signs. Therefore, recognizing when to cease resuscitation attempts is crucial in maximizing the effectiveness of care provided in the field. This is particularly vital in tactical settings where every second counts and resources may be limited.
