    Respiratory Conditions Overview

    • Respiratory diseases can be acute or chronic, affecting airways, lung parenchyma, and other parts of the respiratory system.
    • Common causes include infections, smoking, secondhand smoke, and various air pollutants.
    • Examples of respiratory diseases include asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, pneumonia, and lung cancer.

    Chronic vs. Acute Respiratory Diseases

    • Chronic respiratory diseases are often incurable but can be managed with treatments that alleviate symptoms and enhance daily living.
    • Acute respiratory conditions may be curable, depending on circumstances and causative factors.

    Types of Respiratory Pathology

    • Airway diseases: Affect the airways within the lungs, leading to airflow limitations (obstructive).
    • Lung tissue diseases: Impact lung tissue structure, particularly alveoli.
    • Pleural and mediastinal diseases: Result in restrictive conditions.
    • Lung circulation diseases: Affect blood vessels in the lungs (e.g., pulmonary hypertension).

    Key Concepts in Respiratory Pathology

    • Hypoxemia: Low arterial oxygen levels.
    • Hypercapnia: Elevated carbon dioxide levels in arterial blood.
    • Hypoxia: Insufficient oxygen supply to the body or a region; complete deprivation leads to anoxia.
    • Normal arterial oxygen pressure (PaO2) ranges from 80-100 mmHg.

    Basic Respiratory Physiology

    • Ventilation is a product of respiratory rate and exhaled volume (VE).
    • Hyperventilation: Increased VE resulting in hypocapnia (low carbon dioxide).
    • Tachypnea: Rapid respiratory rate exceeding 20 breaths/min.
    • Bradypnea: Decreased respiratory rate below 12 breaths/min.

    Chronic Obstructive Pulmonary Disease (COPD)

    • COPD consists of chronic bronchitis and emphysema, stemming from chronic inflammation and structural changes.

    Chronic Bronchitis

    • Defined by a cough with sputum lasting at least three months for two consecutive years.
    • Characterized by enlargement of mucosal glands, hyperplasia of goblet cells, and bronchospasms.
    • Symptoms include narrowing of airways, dyspnea, chronic cough, sputum production, and wheezing.

    Important Metrics

    • PaO2/FiO2 ratios:
      • Example calculations:
        • For PaO2 of 80 mmHg: 80/0.21= 380
        • For PaO2 of 100 mmHg: 100/0.21= 475
