    Study Notes

    Obstructive vs Restrictive Lung Disease

    • Obstructive lung disease involves difficulty in exhaling air, leading to air trapping. Examples include asthma and chronic obstructive pulmonary disease (COPD).
    • Restrictive lung disease involves a reduction in lung volume, making it difficult to inhale adequate air. Conditions such as pulmonary fibrosis are examples.
    • Key parameters for distinguishing these types include Forced Expiratory Volume (FEV1) and Forced Vital Capacity (FVC).

    Mobility Assessment

    • Evaluate patient's weight-bearing status to determine mobility assistance needs.
    • Assess levels of independence in daily activities to enhance rehabilitation strategies.

    Chest X-rays (DRS ABCDE Approach)

    • D = Details: Record patient's name, date of birth (DOB), medical record number (MRN), and the date and time of the X-ray.
    • R = RIPE:
      • Rotation: Ensure clavicles are equidistant from the spine, observing alignment of spinous processes.
      • Inspiration: Count number of visible ribs dissecting the midclavicular line for lung inflation assessment (5-6 anterior ribs should be visible).
      • Projection: Identify if the film is AP or PA based on scapular position and film labeling.
      • Exposure: Assess brightness/darkness for adequate lung visibility; hemidiaphragm and vertebrae should be clearly visible.

    Soft Tissues and Bones

    • Examine neck, thoracic wall, breasts, ribs, and assess for asymmetries or previous injuries.
    • Thick soft tissue from conditions like obesity may obscure lung markings on X-ray.

    Airway Assessment

    • Evaluate trachea, bronchi, and hilar structures for any deviations or obstructions.
    • The right main bronchus is shorter, wider, and more vertical than the left, thus more prone to inhaled objects.
    • Abnormalities like hydropneumothorax (air and fluid in pleural space) and tension pneumothorax (increased trapped air) may alter mediastinal structures and require immediate treatment to prevent life-threatening consequences.

    Cardiac Assessment

    • The heart should occupy no more than 50% of the thoracic width on PA chest X-ray; typically 1/3 on the right and 2/3 on the left.
    • Cardiomegaly (enlarged heart) can result from conditions such as valvular heart disease and pulmonary hypertension.

    Diaphragm Assessment

    • Typically, the right hemidiaphragm is higher than the left due to the liver's position.
    • Costophrenic angles should be acute; blunting could indicate fluid accumulation or lung issues like hyperinflation (COPD) or effusion.

    Everything Else

    • Consider additional structures or abnormalities that may not fall under previous categories to ensure comprehensive evaluation.
