مريض في العناية بعد توقف قلب، والفريق يقيّم الموت الدماغي. أي شرط يجب التأكد منه قبل الفحص؟

In ICU after cardiac arrest, the team is assessing brain death. Which prerequisite must be confirmed before testing?

1. No sedatives or severe hypothermia
2. Continuous deep sedation running
3. A body temperature of 33 °C
4. Very low blood pressure during the test
