    Study Notes

    Pneumothorax, Hemothorax, and Hemopneumothorax

    • Pneumothorax: air in the plural cavity that doesn't exit, leading to a collapsed lung
    • Hemothorax: blood in the plural cavity of the thorax
    • Hemopneumothorax: combination of both pneumothorax and hemothorax

    Spontaneous Pneumothorax

    • Typically occurs in 60-65 year olds
    • Caused by rupture of blebs (air-filled cysts) due to increased intrathoracic pressure (sneezing, coughing, pooping) or mechanical causes (blow to ribcage, post-surgical)
    • Smoking is a significant risk factor

    Tension Pneumothorax

    • Occurs when spontaneous pneumothorax fails to close or due to penetrating rib injury
    • One-way valve effect: air enters but cannot exit
    • Mediastinal shift occurs when pressure gets too high, pushing heart and great vessels into unaffected side of chest, away from midline
    • Compresses structures, preventing expansion and blood flow

    Signs and Symptoms

    • Chest pain, unequal chest movement (injured side moves less)
    • Dyspnea, gasping for air, cyanosis, tachypnea, tachycardia
    • Tracheal deviation away from injured side
    • Jugular vein distension (visible or engorged)
    • Diminished breath sounds

    Management

    • High-flow O2, pulse ox
    • Transport ASAP
    • Potential treatment of shock if hemothorax due to blood loss
    • Call EMS
