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.
