الفريق في العناية يُقيم جاهزية مرضى على التهوية الميكانيكية للفطام. كلهم تحسن سبب دخولهم، والعلامات الحيوية مستقرة. أي نتيجة تدل على الجاهزية أكثر؟

The ICU team is assessing several ventilated clients for weaning readiness. All have improving primary conditions and stable vital signs. Which finding indicates readiness most?

1. Alert with a good cough, on FiO2 35% and PEEP 5
2. Needing increasing doses of noradrenaline
3. Needing FiO2 80% and PEEP 14 to keep saturations up
4. Deeply sedated and not responding to voice

Answer: A) Alert with a good cough, on FiO2 35% and PEEP 5. Weaning criteria include improvement of the cause, haemodynamic stability without significant pressors, good oxygenation on low FiO2 (often ≤40%) and low PEEP, and adequate consciousness and cough. A spontaneous breathing trial then follows.
