Study Notes
Respiratory Diseases Overview
- Pulmonary emphysema is characterized by the destruction of the fine alveolar structure of the lungs, leading to the formation of large cystic spaces, initially affecting the upper lobes and eventually all lobes.
- Chronic Obstructive Pulmonary Disease (COPD) is caused by chronic irritation, mainly from smoking and inhalation of injurious agents, leading to three main anatomic derangements in the lungs.
- The pathogenesis of COPD involves chronic inflammatory swelling of the mucosa, which narrows bronchioles, increases resistance to expiration, and causes air trapping in the lungs.
- Management of COPD includes promoting drainage of bronchial secretions, oxygen therapy, bronchodilators, inhaled steroids, and smoking cessation to halt disease progression.
- Lung damage caused by emphysema cannot be restored to normal, and those with Alpha1-Antitrypsin Deficiency are prone to developing emphysema if their levels are low.
- Antitrypsin, an alpha1 globulin, normally inactivates enzymes that may injure alveolar septa, and its deficiency permits enzymes to damage lung tissue.
- Bronchial asthma is characterized by spasmodic contraction of smooth wall muscles of bronchi and bronchioles and increased bronchial mucous secretions in response to various stimuli, with treatment focused on identifying and controlling triggers.
- Neonatal Respiratory Distress Syndrome presents as progressive respiratory distress soon after birth and is treated with adrenal corticosteroids to the mother before delivery, oxygen, and surfactant.
- The pathogenesis of Neonatal Respiratory Distress Syndrome involves inadequate surfactant in the lungs, leading to compromised oxygen exchange and increased permeability of pulmonary capillaries.
- Adult Respiratory Distress Syndrome is characterized by shock as a major manifestation, caused by damage to the alveolar membrane and fluid leaking in, and has a high mortality rate, especially in cases like COVID-19.
- Treatment for Adult Respiratory Distress Syndrome involves treating the underlying condition that caused shock, oxygen ventilator with slightly increased pressure, and has a mortality rate of 30-40%.
