Pneumothorax (Traumatic)
Diagnosis of Traumatic Pneumothorax
Chest x-ray Diagnosis is usually made by chest x-ray. Ultrasonography (done at the bedside during initial resuscitation, Extended Focused Assessment With Sonography in Trauma [E-FAST]) and CT are more sensitive for small pneumothoraces than chest x-ray. The size of the pneumothorax, stated as percent of the hemithorax that is vacant, can be estimated by Diagnosis . The numerical size is valuable mainly for quantifying progression and resolution rather than for determining prognosis.
