Effects in Oxygenation and Hypoxic Pulmonary Vasoconstriction in ARDS Secondary to SARS-CoV2

"Determination of the anti-inflammatory effect. The anti-inflammatory effect is assessed with serum measurement of interleukin 6 (IL-6), C-reactive protein (CRP), ferritin, DHL (lactic dehydrogenase), taken by venipuncture on admission, at 24 and 48 hours.~The following measurements will be performed: pulmonary artery systolic and diastolic pressure (PASP, PADP respectively), central venous pressure (CVP), pulmonary artery occlusion pressure (PAOP), pulmonary vascular resistance (PVR), systemic vascular resistance (SVR), right ventricular stroke work (RVSW) and left ventricular work (LVSW). Stroke volume (and cardiac output) will be computed using the thermodilution technique averaging three consecutive injections with 10 ml of 0.9% saline solution."
