Hypoxic Drive

Mechanism that increases respiratory stimulation when PaO2 falls and inhibits respiratory stimulation when PaO2 climbs
Signs and Symptoms of Chest Wall Injuries
- Blunt or penetrating trauma to chest
- Erythema
- Ecchymosis
- Dyspnea
- Pain on Breathing
- Limited Breath Sounds
- Hypoventilation
- Crepitus
- Paradoxical motion of chest wall
Injuries associated with penetrating thoracic trauma
- Closed pneumothorax
- Open pneumo
- Pneumomediastinum
- Hemothorax
- Hemopneumothorax
- Laceration of vascular structures
- Tracheobronchial tree laceration
- Esophageal Lacerations
- Penetrating cardiac injuries
- Pericardial Tamponade
- Spinal Cord Injuries
- Diaphragmatic penetration/laceration/rupture
- Intra-abdominal penetration with associated organ injury
In pediatric patients more flexible ribs permit more serious internal inury before fracture occurs

In pediatric patients more flexible ribs permit more serious internal inury before fracture occurs
Sternal fracture is associated with:

serious mycoardial injury
Sign and symptoms of hemothorax
- Blunt of penetrating chest trauma
- Signs and symptoms of shock
- Dyspnea
- Dull percussive sounds over site of collecting blood
Signs and symptoms of pulmonary contusion:
- Blunt or penetrating chest trauma
- Increasing dyspnea
- Hypoxia
- Increasing crackles
- Diminishing bhreath sounds
- Hemoptysis
- Signs and symptoms of shock
Blunt cardiac injury may be relieved with:

Oxygen, after severe nagging pain not relieved with rest
Signs and symptoms of pericardial tamponade
- penetrating trauma
- dyspnea and possible cyanosis
- JVD
- Weak thready pulse
- decreasing blood pressure
- Shock
- Narrowing Pulse Pressure
Consider early intubation of the patient with flail chest especially when oxygenation remains impaired despite the provision of high flow high concentration oxygen
- Consider early intubation of the patient with flail chest especially
- when oxygenation remains impaired despite the provision of high flow
- high concentration oxygen
Hemothorax patient may be treated beneficially with:

CPAP, the increased intrathoracic pressure may serve to slow the hemorrhage and increae the partial pressure of oxygen
