Study Notes
Diaphragm and Breathing Mechanics
- In supine position, diaphragm may rise to the nipple line during exhalation.
- Spinal cord injury at C7 results in intercostal muscle paralysis.
- Young children primarily use diaphragmatic breathing due to underdeveloped intercostal muscles.
Pleural Anatomy
- Pleural fluid is located between the visceral and parietal pleurae.
- The thoracic cavity is separated from the abdominal cavity by the diaphragm.
Respiratory Movements
- Rib cage elevation during inhalation occurs due to intercostal muscle contraction.
- Phrenic nerves controlling the diaphragm exit the spinal cord at C3, C4, and C5.
Tidal Volume and Minute Volume
- A decrease in tidal volume leads to a decrease in minute volume if respiratory rate is unchanged.
- Patients with chest injuries and limited inhalation must increase their respiratory rate to maintain adequate minute volume.
Chest Trauma
- Blunt chest trauma can lead to immediate death from traumatic aortic rupture.
- Hemoptysis is characterized by coughing up blood.
- Common symptoms of chest injury include tachypnea, localized pain, and chest wall ecchymosis, but not hematemesis.
Pleurisy and Respiratory Distress
- Pleurisy is characterized by sharp chest pain during inhalation due to irritation of the pleural surfaces.
- Profound cyanosis following a chest injury necessitates prompt ventilation and oxygenation.
Important Outcomes
- Monitoring and understanding breathing mechanics, pleural anatomy, and trauma responses are crucial in emergency medical situations.
