Effects of non-invasive mechanical ventilation on hemodynamic and gas exchanges parameters after cardiac surgery in patients with 300 >PaO 2 /FiO 2 >150

Non-invasive mechanical ventilation (NIV) has been used in hypoxic postoperative cardiac patients but more studies are necessary to clarify its respiratory and hemodynamic effects. Therefore, our objective was to study its effects in the oxygenation index (PaO2/FiO2) and in hemodynamic variables in this group of patients.
