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).
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.
