Defined as ventilatory assistance given without the need for an invasive airway, NPPV is often preferred over invasive mechanical ventilation because it is more convenient to use, more comfortable for the patient, and avoids complications of invasive mechanical ventilation including upper airway trauma, nosocomial pneumonias, sinusitis and sepsis. However, recipients of NPPV must be carefully selected and considerable skill and experience are necessary for successful implementation. This book aims to provide readers with knowledge that will contribute to that success. Noninvasive Positive Pressure Ventilation will inform pulmonary internists and pediatricians, pulmonary physiatrists and physicians, nurses and respiratory therapists who are involved in the management of patients with respiratory failure, critical care physicians and nurses, and trainees and students who have an interest in mechanical ventilation.
