Respiratory failure is a common complication of acute cardiorespiratory disease and exacerbations of chronic respiratory disease. This is the most common form of respiratory failure, and it can be associated with virtually all acute diseases of the lung, which generally involve fluid filling or collapse of alveolar units. Insufficient surfactant production. It is a result of either lung failure, resulting in hypoxemia, or pump failure, resulting in alveolar hypoventilation and hypercapnia.
