[Modification of a continuous positive airway pressure in view of its use in postoperative resuscitation in cardiovascular and thoracic surgery].

This paper describes a modification of a CPAP "P.P" circuit. This modified circuit is used to wean from artificial ventilation: 1) Patients exhibiting an hypoxia when undergoing a T piece trial with high FiO2. 2) Patients presenting pulmonary pathology before the operation. 3) Patients with cardiogenic shock so long as controlled mandatory ventilation is not an absolute requirement. This modification of a CPAP "P.P" circuit may have general use in the post-operative care after cardiovascular and thoracic surgery.
