How should Amy check for life-threatening bleeding while assessing Theo?

When assessing for life-threatening bleeding, the recommended approach is to do so while simultaneously checking for pulse and breathing. This method allows the responder to quickly evaluate the patient's overall condition and identify any critical issues, such as severe bleeding, that need immediate attention.

Life-threatening bleeding requires prompt identification because it can lead to shock and death within minutes if not managed appropriately. By checking for bleeding during the assessment of pulse and breathing, the responder can implement necessary interventions, such as applying pressure to the wound or positioning the patient appropriately, more rapidly.

This integrated approach ensures that multiple life-threatening conditions are being monitored concurrently, maximizing the effectiveness of the assessment and response. Other methods, such as checking for bleeding only before or after starting CPR, or relying on mentions from others to identify bleeding, may delay critical interventions and negatively impact the patient's chances of survival.
