رجل عمره ٦٤ سنة في العناية عنده قسطرة وريدية مركزية في الوداجي الداخلي. أثناء تغيير الغطاء انفصل الوصل ودخل هواء، وصار عنده فجأة ضيق نفس وألم صدر وتشوش. الضغط ٧٨/٤٨، والنبض ١٢٨، والتشبع ٨٦٪. ما الوضعية الصحيحة؟

A 64-year-old man in ICU has an internal jugular central line. During a cap change the connection came off and air entered; he suddenly becomes breathless with chest pain and confusion. BP 78/48, HR 128, SpO2 86%. What is the correct position?

1. Right side with the head raised to 90 degrees
2. Left side with the head down (Trendelenburg)
3. Sitting with the legs dangling off the bed
4. Prone with the legs raised

Answer: B) Left side with the head down (Trendelenburg). Air embolism is managed by closing the air source, giving oxygen and placing the client left lateral with head down so the air stays in the right atrium away from the pulmonary outflow. Valsalva during cap changes helps prevent it.
