Non-Invasive Ventilation involves the use of a mask to assist breathing for patients who can’t breathe for themselves, providing an alternative to invasive ventilation, which involves the insertion of a tracheal tube into the throat of an unconscious patient. It can be used for many problems involving breathing difficulties such as lung disease and sleep apnoea. This book provides a clear practical guide to medical practitioners on how to make use of NIV under various conditions. The approach is very applied and easy to understand. New additions for this second edition include chapters on cough assist devices and non-invasive ventilation at home, and an expansion of the chapters on long-term ventilation and physiotherapy.
