When treating a patient who experienced a pulmonary blast injury, you should:

• A. Use a demand valve to ventilate the patient.
• B. Avoid giving oxygen under positive pressure.
• C. Administer large amounts of intravenous fluid.
• D. Suspect an accompanying cardiac tamponade.

Answer: (B)

When treating a patient with a pulmonary blast injury, one of the key considerations is the potential for barotrauma, which can occur due to the explosive forces affecting the lungs and airways. This can lead to conditions such as pneumothorax or ruptured alveoli. Administering oxygen under positive pressure, as would be the case with certain forms of mechanical ventilation, may exacerbate these injuries by increasing the pressure within the thoracic cavity, possibly causing further damage to the lung tissue or leading to additional complications like tension pneumothorax. Thus, avoiding oxygen under positive pressure is crucial to minimize the risk of worsening any existing injuries caused by the blast. The focus should instead be on maintaining adequate ventilation and oxygenation while being cautious about the pressures involved in treatment. In settings where blast injuries are suspected, other interventions may include careful monitoring and support without the use of invasive ventilation techniques that could increase thoracic pressure.
