Speckle Tracking and Inhaled Nitric Oxide in Acute Respiratory Distress Syndrome

"The intervention within the framework of the protocol will consist, for the needs of the study, in performing 2 TEE and 5 TTE in 24 hours after~For TEE:~* The first TEE will allow us to evaluate the right ventricle, to look for the existence of a acute cor pulmonale, to evaluate the patient's blood volume as recommended during the management of ARDS. If the patient is included in the study, our intervention will consist in leaving this TEE in place in order to perform measurements at H0, 30min, H1 and H2 after iNO administration.~* The second TEE will be performed at H24 to performed new measurements."

"For TTE:~• The TTEs will allow us to evaluate the anatomy of the right ventricle, to estimate the systolic pulmonary artery pressure, to calculate the cardiac output and to measure the conventional parameters of the right ventricular systolic function. This noninvasive examination will be repeated at 30 min, H1, H2, and H24 after iNO administration"
