Study Notes
Diagnosis of Respiratory Disorders
- Objective is to understand the diagnosis of respiratory disorders, covering symptoms, examinations, and diagnostic procedures.
- Common presenting symptoms include cough and dyspnea, key indicators of respiratory diseases.
Types of Respiratory Disorders
- Obstructive Disorders: Primarily caused by airway diseases such as asthma, chronic obstructive pulmonary disease (COPD), bronchiectasis, and bronchiolitis.
- Restrictive Disorders: Include parenchymal lung diseases, chest wall abnormalities, and neuromuscular conditions.
- Vascular Diseases: Include pulmonary embolism, pulmonary hypertension, and pulmonary venoocclusive disease.
Gas Exchange Abnormalities
- Disorders may be grouped based on gas exchange issues: hypoxemia, hypercarbia, or combined impairments.
Symptoms of Dyspnea and Cough
- Dyspnea: Can stem from various non-lung pathologies. Commonly experienced as "chest tightness" in obstructive diseases and "air hunger" in congestive heart failure.
- Acute dyspnea can indicate issues like airway narrowing, hypoxemia, or sudden changes in breathing workload; chronic dyspnea may be gradual, associated with COPD or idiopathic pulmonary fibrosis (IPF).
-
Cough Types:
- Acute cough persists up to three weeks; commonly suggests respiratory infection.
- Subacute cough lasts three to eight weeks.
- Chronic cough exceeds eight weeks, often linked to obstructive lung diseases or gastroesophageal reflux.
Additional Symptoms
- Wheezing indicates airway disease, while hemoptysis can be due to infections or lung cancer.
- Chest pain might signal pleural diseases or pulmonary vascular issues.
- Cigarette smoking and e-cigarette use are significant risk factors for respiratory noncommunicable diseases.
Physical Examination Findings
- Inspection: Patients may exhibit respiratory distress; kyphoscoliosis can cause restrictive pathology.
- Percussion: Helps identify lung size and presence of effusion (dull sound) or pneumothorax (hyper-resonant sound).
- Palpation: Assesses lung expansion and can reveal subcutaneous air or tactile fremitus differences.
Auscultation Techniques
- Wheezes indicate airway blockages; rhonchi suggest secretions in airways and may hint at bronchiectasis.
- Crackles are associated with alveolar diseases or conditions causing pulmonary edema.
- Egophony and whispered pectoriloquy may indicate areas of lung consolidation, commonly seen in pneumonia.
Systemic Examination Indicators
- Pedal Edema: Symmetric suggests cor pulmonale; asymmetric could indicate deep venous thrombosis.
- Jugular Venous Distention: Indicates right heart failure.
- Pulsus Paradoxus: A feature of obstructive lung disease, indicating high negative intrathoracic pressure.
- Clubbing: Associated with conditions like cystic fibrosis and IPF.
- Cyanosis: Evident in severe hypoxemia.
Diagnostic Evaluation
- Initial assessment typically utilizes spirometry for pulmonary function testing. This effort-dependent test evaluates obstructive pathophysiology, noting forced expiratory volume in the first second (FEV1) relative to forced vital capacity (FVC).
