Document Summary
Common lung diseases pulmonary circulation, restrictive lung, airway diseases. Chronic obstructive pulmonary disease (copd: bronchitis. Pulmonary embolism: blockage in a pulmonary artery. Pulmonary hypertensions: high blood pressure in the arteries of the lung, can ultimately lead to right heart failure. Pulmonary hemorrhage (bleeding: acute injury to the lung. Increased work of breathing: increased respiratory muscle o2 demand. Fibrosis also impairs gas transfer at the alveolar-capillary surface. Scoliosis: severe lateral curve in the spine: deformation in the chest wall, limited chest movement, reduced lung volumes. Pulmonary fibrosis: scar tissues: caused by infections, environmental agents (asbestos/silica), and chronic inflammation. Sarcoidosis: immune disease: causes lumps of fibrous tissues called granulomas on the skin/organs, all levels of lung volume decreases and the respiratory rate increases. Exercise: ventilation increased by increased respiratory rate as opposed to tidal volume, reduction in max. Sv: greater competition between respiratory and locomotive muscles for a lower total o2 supply. Normally 75-80% of breathe comes out in the: treatment:
