A Case-Based Approach to Noninvasive Positive Pressure Ventilation

Abstract

Noninvasive positive pressure ventilation (NIPPV) has revolutionized the concept of mechanical ventilation with the major benefit of avoiding invasive mechanical ventilation in specific situations, thereby preventing associated complications. Noninvasive positive pressure ventilation has emerged as the first line of management of hypercapnic respiratory failure (due to chronic obstructive pulmonary disease and neuromuscular weakness) and cardiogenic pulmonary edema in addition to standard therapy in the acute setting. There is improvement in gas exchange, relief of respiratory muscle fatigue, and clinical outcome with reduced morbidity and mortality. Nevertheless, contraindications and failures need to be identified early, as delaying endotracheal intubation is associated with increased morbidity and mortality. Despite overwhelming evidence to support its use, NIPPV is underused. Residents and hospitalists need to identify NIPPV as a treatment option in acute respiratory failure.
