Abstract Cardiac surgery patients who undergo valve replacement or coronary artery bypass surgeries; have greater postoperative risk for developing pulmonary complications due to their limitations in pulmonary function caused by sternotomy, inflammatory response of bypass machine, ventilator induced lung injury(VILI) and drugs So, Respiratory complications ranges from atelectasis to respiratory insufficiency and even failure could occur in the post-operative period . Although invasive endotracheal mechanical ventilation has remained the cornerstone of ventilatory strategy for many years for severe ARF, several studies have shown that mortality associated with pulmonary disease is largely related to complications of postoperative reintubation and mechanical ventilation. Therefore, major objectives for anesthesiologists are first to prevent the occurrence of postoperative complications and second to ensure oxygen administration and carbon dioxide elimination, avoiding intubation if ARF occurs. Noninvasive ventilation (NIV) does not require an artificial airway (endotracheal tube or tracheotomy), and its use is well established to prevent ARF occurrence (prophylactic treatment) or to treat ARF to avoid reintubation (curative treatment). |
