Abstract
Morbid obese patients who undergo upper abdominal surgery havegreater postoperative risk for developing pulmonary complications due to their limitations in pulmonary function. Oxygen administration is efficient in the treatment of the majority of hypoxemia cases. PaO2 will be supported while oxygen mask isn’t the appropriate tool for recruitment of the collapsed alveoli. So respiratory complications and respiratory insufficiency might occur in the PO period of abdominal surgery. In addition to, 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 removal while 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.
