Study Notes

Respiratory Diseases Overview

Pulmonary emphysema leads to destruction of alveolar structure and formation of large cystic spaces in the lungs, initially affecting upper lobes and eventually all lobes.
Chronic Obstructive Pulmonary Disease (COPD) is caused by chronic irritation, mainly from smoking and inhalation of injurious agents.
Three main anatomic derangements in COPD: inflammation and narrowing of terminal bronchioles, dilation and coalescence of pulmonary air spaces, and loss of lung elasticity.
The pathogenesis of COPD involves chronic inflammatory swelling of mucosa, accumulation of leukocytes releasing proteolytic enzymes, and air trapping in the lungs.
Management of COPD includes bronchodilators, inhaled steroids, oxygen therapy, lung therapy/exercise, and promoting drainage of bronchial secretions to decrease pulmonary infections.
Lung damage caused by emphysema is irreversible and cannot be restored to normal.
Alpha1-Antitrypsin Deficiency increases the risk of emphysema development, especially in cases of severe deficiency affecting lower lobes of the lungs.
Bronchial Asthma involves spasmodic contraction of bronchial muscles, increased mucous secretions, and can be triggered by various stimuli.
Treatment of Bronchial Asthma includes identifying and controlling triggers, using fast-acting and long-acting bronchodilators, and drugs that reduce airway reactivity.
Neonatal Respiratory Distress Syndrome leads to progressive respiratory distress soon after birth, particularly in premature infants, infants delivered by cesarean section, and infants born to diabetic mothers.
Adult Respiratory Distress Syndrome is characterized by shock, caused by damage to the alveolar membrane and fluid leakage, with a high mortality rate, especially in cases like COVID-19.
Treatment of Adult Respiratory Distress Syndrome involves addressing the underlying condition, oxygen ventilation with slightly increased pressure, and has a high mortality rate.
