Trial to Evaluate an Optimization Procedure of Alveolar Recruitment During Transport Performed by Nurse Anesthetists in Intensive Care

Changing respiratory support and multiples endotracheal tube disconnections may induce a loss of PEEP and finally lead to alveolar derecruitment. This study is an evaluation of a care procedure to limit the incidence of alveolar derecruitment in ventilated intubated ICU patients during transport for CT scan. Intra hospital transport of ICU patients are performed by anesthesiologist nurses, the physician entrusts them this activity. This is a randomized controlled study, the procedure is to clamp endotracheal tube before each disconnection from ventilator.
