Pneumothorax - Ans:✔✔-air in the pleural cavity
Tension Pneumothorax - Ans:✔✔-a type of pneumothorax in which air that enters the chest cavity is
prevented from escaping
cause of pneumothorax and hemothorax - Ans:✔✔-any injury that lets air, blood, or fluid in pleural space
such as rib fracture
What is the difference between a tension pneumothorax and a pneumothorax - Ans:✔✔-A tension
pneumothorax is where air is trapped in the pleural space and cannot escape
Signs and symptoms of pneumothorax - Ans:✔✔-asymmetry of the chest, restlessness, anxiety,
respiratory distress, SOB, absence of breath sounds on one side, decreased cardiac output
LATE SIGN is tracheal deviation and low BP
Diagnosis of tension pneumothorax - Ans:✔✔-chest x-ray
Treatment of pneumothorax - Ans:✔✔-chest tube
