In different sections of this book the relationships between the patterns of psychological response in acute and chronic respiratory failure, as well as the epidemiology of neuropsychiatric disorders in ventilator management, are collected and analyzed. Main concepts such as "vulnerability to stress", critical illness-psychological stress and susceptibility that may develop during NIV support, as well as the diagnosis of neuropsychiatric disorders in respiratory failure are also summarized. A section is devoted to the most frequent indications of NIV, also including a special use of NIV in pandemic and high-risk infections, as well as in several other conditions such as acute and chronic respiratory failures and neurological disorders. A summary of practical approaches for treatment and prevention in neurologic and psychiatric disorders during noninvasive mechanical ventilation, as well as the perspective in terms of outcomes, quality-of-life, palliative care is also given. The book is intended for all those healthcare professionals treating patients suffering from neurological or psychiatric disorders and who develop acute or chronic respiratory failure.  Neurologists, psychiatrists, pulmonary critical care professionals, geriatricians, internists and psychologists will find in the book a valuable guide for their everyday clinical practice.
