The primary ethical imperative in this scenario is the preservation of human life. Delaying the surgery is guaranteed to result in the patient's death, an irreversible and catastrophic outcome. The principle of beneficence (acting in the patient's best interest) and non-maleficence (avoiding harm) strongly support immediate action. While bypassing security protocols is a serious violation, the protocols themselves are inadvertently causing the ultimate harm in this specific, unforeseen situation. In a life-threatening emergency where the patient cannot consent, there is a widely accepted ethical principle of implied consent for life-saving treatment. Therefore, acting to save the patient's life, even without explicit consent from the blocked-out medical staff, is the most justifiable course of action.
