Which parameter should be monitored to assess progression in blunt chest trauma with respiratory failure?

• A. Hair color
• B. Blood type
• C. ABGs
• D. Coping mechanisms

Answer: (C)

Monitoring gas exchange and acid-base status is essential in blunt chest trauma with respiratory failure. Arterial blood gases give objective data on oxygenation (PaO2), ventilation (PaCO2), and acid-base balance (pH, bicarbonate). Serial ABGs show how well the lungs are delivering oxygen and removing CO2 as injuries like contusion, edema, pneumothorax, or hemothorax evolve or respond to treatment. This information guides clinical decisions such as adjusting oxygen therapy and ventilator settings (for example, FiO2 or PEEP) and detects worsening gas exchange that may require escalation of support. Hair color and blood type do not reflect respiratory status, and coping mechanisms relate to psychological adaptation rather than physiologic progression.
