Clinical diagnostic of brain death requires a non-reactive coma, absence of brain stem reflex, and absence of spontaneous breathing. The confirmation of absence of spontaneous breathing is established the apnea test (according to the American Academy of Neurology's Guidelines). However this test may lead to complications (acute hypoxemia, ventilatory and cardiocirculatory disorders) and reduces significantly the number of lung transplants. Some data suggest modifying the apnea test : replace the ventilator switching off with continuous positive airway pressure (CPAP) use. These studies showed that this alternative method (CPAP) increased the level of lung harvest but they were not sufficient because these studies were monocentric, non randomized and with little patients,. That why the aim of the present study is to compare the standard strategy and CPAP strategy with a prospective, multicenter, randomized study.

Condition Intervention
Alternative Method of Apnea Test Procedure: Apnea test - control Procedure: Apnea test - CPAP

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
