Pulmonology is a medical specialization concerned with the diseases of the respiratory tract. Managing patients who require mechanical ventilation and life support is under the scope of this field. Conditions of the chest such as asthma, tuberculosis, pneumonia, chest infections and emphysema are treated using pulmonary medicine. Such conditions arise due to a number of reasons, such as genetics, exposure to toxins and infectious agents, or due to an autoimmune response of the body. Some hereditary pulmonary diseases are alpha 1-antitrypsin deficiency and cystic fibrosis. Pulmonary function tests, spirometry, blood tests, chest X-rays, CT scanning, etc. are some of the diagnostic techniques used in pulmonology. Oral and inhalation medication, oxygen therapy, pulmonary rehabilitation, etc. are common strategies often employed in pulmonary disease management. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of pulmonology. The objective of this book is to give a general view of the varied respiratory conditions and their management techniques. The extensive content of this book provides the readers with a thorough understanding of the subject.
