Study Notes
Chest Injuries Overview
- Ventricular Fibrillation: Occurs when a significant impact to the chest happens during a critical cardiac cycle, leading to cardiac arrest.
- Flail Segment: Indicated by a flail chest section causing respiratory distress and low oxygen saturation; usually associated with pulmonary contusion.
- Open Pneumothorax: A wound allowing air movement into the pleural space during ventilation; poses hazards of hypoxia and respiratory distress.
Cardiovascular Complications
- Myocardial Contusion: Rapid and irregular pulse following blunt chest trauma suggests this cardiac injury, can lead to serious complications.
- Cardiac Tamponade Indicators: Assess for engorged jugular veins, especially in cases of trauma suggesting fluid accumulation around the heart.
Respiratory Symptoms & Assessments
- Respiratory Distress Signs: Includes shallow breathing, cyanosis, and hypotension indicative of shock; necessitate immediate ventilation support.
- Hemoptysis: Defined as coughing up blood, which can be indicative of serious lung or chest injury.
- Pleural Fluid Location: Found between the visceral and parietal pleurae, crucial for understanding fluid collection diseases.
Pneumothorax & Emergency Response
- Tension Pneumothorax Symptoms: Includes absent breath sounds on affected side, severe cyanosis, and altered mental status; immediate needle decompression is critical for treatment.
- Subcutaneous Emphysema: Presence indicates air leaking into tissues from a lung injury.
- Ventilation Risks: High caution when managing positive-pressure ventilation in cases of pneumothorax to avoid worsening the injury.
Examination Findings
- Shock Symptoms: Signs such as hypotension and tachycardia indicate possible internal bleeding like hemothorax.
- Laceration of Aorta: High suspicion for this injury in unrestrained motor vehicle accident patients presenting with significant shock and altered consciousness.
Management Protocols
- Open Wound Care: In cases of open chest wounds, maintain a seal but be ready to partially remove the dressing if respiratory distress increases.
- Immediate ALS Support: Essential for patients with severe labored breathing and significant chest trauma for advanced airway management.
Anatomy and Functionality
- Intercostal Muscle Function: Contraction during inhalation elevates the rib cage, essential for effective breathing mechanics.
- Supine Breathing Mechanics: Diaphragm position may rise to the nipple line during exhalation, complicating trauma assessments.
Additional Signs
- JVD and Hemothorax: Jugular venous distention may indicate large volume blood loss and pressure changes within the thoracic cavity, vital for assessment of traumatic injuries.
