Study Notes
- EMTs (Emergency Medical Technicians) need to be proficient in the emergency management of chest injuries, including assessment techniques, understanding different types of chest injuries, and their underlying pathophysiology of lung injuries
Assessment Techniques
- Rapidly assess the patient's airway, breathing, and circulation (ABCs)
- Look for signs of respiratory distress, such as increased respiratory rate, use of accessory muscles, and cyanosis
- Monitor vital signs, including heart rate, blood pressure, respiratory rate, and oxygen saturation
- Inspect the chest for obvious injuries, such as open wounds, bruising, or deformities
- Palpate the chest wall for tenderness, crepitus (subcutaneous emphysema), or instability
- Auscultate breath sounds to assess for the presence of air movement in all lung fields
- Note any abnormal breath sounds, such as wheezing, rales, or absent breath sounds
Types of Chest Injuries
- Blunt trauma: Caused by a direct blow to the chest without penetrating the skin
- Penetrating trauma: Occurs when an object pierces the chest wall
- Rib fractures: A common injury caused by blunt trauma; can lead to pain, difficulty breathing, and potential injury to underlying structures
- Flail chest: Occurs when multiple ribs are fractured in multiple places, resulting in a free-floating segment of the chest wall
- Pulmonary contusion: Bruising of the lung tissue, often caused by blunt trauma, leading to inflammation and impaired gas exchange
- Pneumothorax: Accumulation of air in the pleural space, causing lung collapse; can be spontaneous or caused by trauma
- Tension pneumothorax: A life-threatening condition where air accumulates in the pleural space and cannot escape, leading to compression of the heart and great vessels
- Hemothorax: Accumulation of blood in the pleural space, often caused by trauma
- Cardiac tamponade: Compression of the heart caused by fluid accumulation in the pericardial sac, impairing cardiac filling and output
- Traumatic asphyxia: Results from a sudden, severe compression of the chest, leading to backflow of blood from the heart and great vessels into the head and neck
Pathophysiology of Lung Injuries
- Pulmonary contusion: Causes inflammation, edema, and hemorrhage within the lung tissue, impairing gas exchange and leading to hypoxemia
- Pneumothorax: Air enters the pleural space, disrupting the negative pressure that keeps the lung inflated, causing the lung to collapse
- Tension pneumothorax: As air accumulates in the pleural space, it compresses the mediastinum, impairing venous return to the heart and reducing cardiac output
- Hemothorax: Blood in the pleural space occupies volume and compresses the lung, impairing ventilation and gas exchange
- Open pneumothorax: A penetrating chest wound allows air to be sucked into the pleural space during inhalation, worsening lung collapse
Emergency Management
- Ensure scene safety
- Maintain spinal stabilization if there is a suspicion of spinal injury
- Administer high-flow oxygen
- Assist ventilation with a bag-valve mask if the patient is not breathing adequately
- Seal open chest wounds with an occlusive dressing taped on three sides to allow air to escape during exhalation but prevent air from entering during inhalation
- Monitor the patient's vital signs closely
- Be prepared to manage tension pneumothorax by performing needle decompression
- Transport the patient to the appropriate medical facility
