Study on the Effectiveness and Feasibility of Prone Position Ventilation Technology in Congenital Heart Disease

"1. Inform the children's family members of the purpose and method of prone position ventilation~2. Assess the fixation of various catheters~3. Suspend feeding before placing prone position~4. Confirm the time to start prone position ventilation under the joint assessment of medical staff~5. Place the child in a prone position with the participation of researchers, doctors and nursing staff, with the child's head tilted to one side to avoid damage to the eyes and nose due to compression, and the arms are bent upward to form a W . Bend both lower limbs downward to form an M shape, and use a soft pillow cushion to measure the knee joints to avoid compression~6. The whole process ensures the smooth fixation of tracheal intubation and various catheters~7. Proper sedation during prone position ventilation to achieve good human-machine synchronization~8. At least 6-8 hours in prone position every day"
