Which set of vital signs is typically monitored during casualty care in the field?

• A. Respiratory rate, heart rate, blood pressure, mental status, and oxygen saturation if available
• B. Respiratory rate and temperature only
• C. Oxygen saturation, blood pressure, and glucose level
• D. Pulse rate and respiratory rate only

Answer: (C)

Monitoring oxygenation, perfusion, and metabolic status is crucial in field casualty care. Oxygen saturation shows how well the casualty is oxygenating and helps decide on supplemental oxygen or airway support. Blood pressure reveals perfusion to the brain and other vital organs, guiding fluid resuscitation or additional interventions. Glucose level checks for metabolic emergencies like hypoglycemia that can rapidly worsen mental status or resemble other injuries, and it’s quick to assess with a portable glucometer. Together, these three measurements provide immediate, actionable insight with limited equipment, making them the most practical and comprehensive set to monitor in the field.
