Study Notes
General Manifestations of Respiratory Disease
- Breath sounds can be abnormal, including rales (light bubbly or crackling sounds), rhonchi (deeper or harsher sounds), and absence (non-aeration or collapse of lungs)
- Dyspnea is a feeling of discomfort or shortness of breath, often caused by increased carbon dioxide or hypoxemia (low oxygen levels in the blood)
Symptoms of Respiratory Distress
- Paroxysmal nocturnal dyspnea is a sudden, acute type of dyspnea that wakes patients up from sleep with coughing and gasping for breath
- Orthopnea occurs when lying down and is usually caused by pulmonary congestion
- Cyanosis is a bluish coloring of skin and mucous membranes caused by large amounts of unoxygenated hemoglobin in the blood
- Pleural pain results from inflammation or infection of the parietal pleura
- Friction rub is a soft sound produced by rough, inflamed, or scarred pleural surfaces moving against each other
- Clubbed digits are a result of chronic hypoxia associated with respiratory or cardiovascular diseases, characterized by painless, firm, fibrotic enlargement at the end of the digit
Infectious Diseases
- Lower respiratory tract infections include bronchiolitis (viral infection caused by respiratory syncytial virus) and pneumonia (3 types: lobar, bronchopneumonia, and interstitial)
- Cystic fibrosis is an inherited disorder that affects exocrine glands, causing abnormally thick secretions that obstruct airflow and lead to infections and respiratory failure
Obstructive Lung Diseases
- Cystic fibrosis causes sticky mucus to obstruct airflow, leading to air trapping, atelectasis, and permanent damage to bronchial walls
- Bronchiectasis is a permanent enlargement of parts of the airways, characterized by chronic cough with mucus production, shortness of breath, coughing up blood, and chest pain
- Emphysema is a long-term, progressive disease of the lungs that causes shortness of breath due to over-inflation of the alveoli
- Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disorder characterized by progressive tissue degeneration and airway obstruction
- Asthma is an inflammation of the mucosa with edema, bronchoconstriction, and increased secretion of thick mucus that blocks airways
Expansion Disorders
- Atelectasis is the collapse of a lung or part of a lung, leading to decreased gas exchange and hypoxia
- Common causes of atelectasis include hypoventilation, compression, airway obstruction, and adhesions
- Pleural effusion is excessive fluid in the pleural cavity, increasing pressure and leading to separation of the pleural cavity
- Pneumothorax is air leakage, with 3 types: closed, open, and tension
- Flail chest is a fracture of ribs that allows independent movement during respiration, preventing expansion of the affected lung
