Idiopatic pulmonary fibrosis (IPF) represents one of the most important devastating diseases that affects the lungs. Traditionally, the development of acute or chronic respiratory failure in disiorepresents an important dilemma for pulmonologists, intensivists, internists and anesthesiologists, due to the limited respiratory and functional reserve of these patients. In the last decade, we have witnessed a novel development of non-invasive mechanical ventilation and high flow oxygenation systems, representing an attractive option for patients compared to those patients with well-known poor results of invasive mechanical ventilation. In this book, we analyze all the options of non-invasive mechanical ventilation, indications, ventilatory modes, protocols, technology, equipment and applications in acute and chronic phase of patients with IPF, in addition to an exhaustive approach of all complementary techniques that optimize the application of these procedures. There are no previous descriptions or updates that incorporate this comprehensive analysis. This book, thus, serves as an updated scientific and practical reference for the knowledge of all spectrum respiratory failure presentations in idiopatic pulmonary fibrosis.
