Study Notes
Vital Signs - Norms and Ranges
- Normal blood pressure typically ranges from 90/60 mmHg to 120/80 mmHg.
- Hypertension is defined as sustained blood pressure over 130/80 mmHg.
- Orthostatic hypotension involves a drop in blood pressure when standing, often assessed by a decrease of 20 mmHg systolic or 10 mmHg diastolic.
- Normal SpO2 levels range from 95% to 100%, indicating adequate oxygen saturation.
Spirometry Interpretation
- Spirometry measures lung function and can identify obstructive and restrictive diseases.
- The GOLD classification stages COPD severity based on FEV1 (Forced Expiratory Volume in 1 second):
- Stage I: FEV1 ≥ 80% predicted
- Stage II: FEV1 50-79% predicted
- Stage III: FEV1 30-49% predicted
- Stage IV: FEV1 < 30% predicted or FEV1 < 50% with respiratory failure.
Signs, Symptoms, and Basic Pathology of CAD and Heart Failure
- Coronary Artery Disease (CAD): Characterized by inadequate blood supply to the heart due to arterial blockages, leading to myocardial ischemia.
- Angina Pectoris: Chest discomfort during exertion due to decreased oxygen supply to the heart; can radiate to jaw, shoulder, and back.
- Acute Myocardial Infarction (MI): Symptoms divide into two types based on wall thickness - STEMI involves significant obstruction, while NSTEMI may not.
-
Heart Failure:
- Two types: Systolic heart failure (Type 1) with decreased ejection fraction, and diastolic heart failure with preserved ejection fraction.
- Symptoms include fatigue, fluid retention causing pulmonary and peripheral edema, and syncope.
Diagnostic Approaches
- CAD Diagnosis: Commonly includes cardiac stress testing and coronary angiography to visualize arterial blockages.
- Angina Evaluation: Criteria include ECG changes and troponin levels to identify myocardial ischemia.
- Heart Failure Evaluation: Diagnostic criteria involve assessing ejection fraction and symptoms of fluid overload.
Aetiology of COPD and Restrictive Lung Disease
-
COPD:
- Caused by significant exposure to noxious particles or gases, especially from smoking or environmental pollutants.
- Affects airflow and lung tissue through chronic inflammation.
- Asthma: Primarily linked to exposure to allergens or irritants leading to reversible airway obstruction.
- Emphysema: Characterized by damage to alveolar walls from long-term exposure to irritants, reducing gas exchange efficiency.
- Chronic Bronchitis: Frequent productive cough lasting at least three months per year for two consecutive years, often associated with mucus obstructing airflow.
Management Strategies
-
COPD Management:
- Aimed at controlling symptoms and reducing exacerbations through medication (inhalers, bronchodilators).
- Smoking cessation is crucial.
- Asthma Management: Involves the use of inhaled corticosteroids and bronchodilators to manage acute symptoms and long-term control.
- Chronic Bronchitis Management: Focused on expectoration and reducing irritant exposure; includes physical therapies to improve lung function.
Summary of Key Concepts
- Understanding vital signs is essential for diagnosing and managing cardiovascular and respiratory issues.
- Recognizing the symptoms and pathology of CAD and heart failure aids in prompt treatment.
- Knowledge of the aetiology and management of COPD and restrictive lung diseases is critical for effective patient care.
Vital Signs: Norms and Ranges
- Hypertension: Blood pressure consistently above 130/80 mmHg.
- Orthostatic hypotension: A drop in blood pressure of 20/10 mmHg on standing, indicating fluid volume depletion or autonomic dysfunction.
- Spo2: Normal range is 95-100% oxygen saturation; below 90% indicates hypoxemia.
Spirometry Interpretation
- GOLD classification for COPD:
- Stage I: Mild - FEV1 ≥ 80% predicted.
- Stage II: Moderate - FEV1 50-80% predicted.
- Stage III: Severe - FEV1 30-50% predicted.
- Stage IV: Very Severe - FEV1 < 30% predicted.
Signs, Symptoms, and Basic Pathology of CAD and Heart Failure
- Coronary Artery Disease (CAD):
- Inadequate blood supply to the heart due to vessel blockage.
- Symptoms include discomfort in chest, jaw, shoulder, and back.
- Angina Pectoris:
- Characterized by chest pain due to insufficient oxygen supply.
- Triggered by exertion; relieved by rest.
- Acute Myocardial Infarction (MI):
- Two types based on ventricular wall thickness:
- Transmural (full thickness).
- Subendocardial (partial thickness).
- Two types based on ventricular wall thickness:
- Heart Failure:
- Type 1: Systolic failure with reduced ejection fraction.
- Symptoms include pulmonary and peripheral edema, fatigue.
- Fluid retention and liver enlargement common.
Diagnosis of CAD and Heart Failure
- CAD:
- Diagnosed using cardiac stress testing and coronary angiography.
- Angina Pectoris:
- Assessed through stress tests; ECG may show abnormalities.
- Acute MI:
- Criteria include elevated troponin and ischemic symptoms.
- Heart Failure:
- Evaluated through ejection fraction measurement on echocardiogram.
Aetiology of COPD and Restrictive Lung Disease
- COPD:
- Significant exposure to noxious particles or gases leading to airway obstruction.
- Major risk factor: smoking.
- Asthma:
- Caused by environmental exposures, asthma-related triggers, and allergens.
- Emphysema:
- Destruction of alveolar walls without fibrosis; gas exchange impaired.
- Chronic Bronchitis:
- Characterized by chronic cough with sputum production for at least 3 months.
Management Strategies
- COPD:
- Control risk factors, medication to reduce airway inflammation, and manage symptoms.
- Asthma:
- Controller medications (e.g., corticosteroids) to prevent exacerbations.
- Rescue medications (e.g., bronchodilators) for acute symptoms.
- Chronic Bronchitis:
- Management focuses on symptom relief and preventing exacerbations, often through inhaled medications.
Miscellaneous
- Factors influencing lung diseases:
- Genetic predisposition, socio-economic status, and allergies.
- Compounding factors include viral infections and poor air quality.
- General health management includes breathing exercises, lifestyle modifications, and medications tailored for severity.### Childhood Allergies
- Hereditary tendencies can lead to childhood allergies.
- Exposure to allergens like dust, mould, and fur can trigger allergic reactions.
Pathophysiology
- Common preventable and treatable chronic airway diseases.
- Airway inflammation is typically chronic and can be exacerbated by smoking.
- Persistent respiratory symptoms may arise from inhaled corticosteroid use.
- Obesity increases complexity in treatment and management of respiratory diseases.
Clinical Features
- Barrel chest appears as a physical manifestation of airway disease.
- Common symptoms include wheezing, shortness of breath (SOB), cough, and chest tightness.
- Decreased breath sounds on auscultation indicate worsening respiratory conditions.
- Oxygen desaturation may occur during early morning due to alveolar destruction.
- Hyperinflation observed on chest radiographs typically varies over time.
- Exercise capacity can be affected by viral infections, impacting immune response.
Diagnostic Tools
- Gold Standard assessments include symptom evaluation using tools like the MRC scale.
- CAT ax tool helps assess exposure impacts and determine appropriate management strategies.
Environmental Impact
- Changes in weather, environmental irritants, and allergens contribute to airway conditions.
- Persistent inflammation results from exposure to noxious agents, affecting lung health.
