Which vital signs should be monitored on a wilderness patient?

• A. Level of Consciousness, Pulse Rate and Rhythm
• B. Respiratory Rate and Effort, and Blood Pressure If Feasible
• C. Skin Color/Temperature, Capillary Refill, and Pupil Response
• D. Level of Consciousness, Pulse Rate and Rhythm, Respiratory Rate and Effort, Blood Pressure If Feasible, Skin Color/Temperature, Capillary Refill, Pupil Response; Oxygen Saturation If Available

Answer: (D)

Monitoring a broad range of vital signs provides the clearest picture of how a patient is doing and how they’re responding to treatment, especially in the wilderness where conditions change quickly and you may have limited resources. The best practice is to check as many of these signs as feasible: level of consciousness to gauge mental status and airway protection; pulse rate and rhythm to assess perfusion and detect potential shock or arrhythmias; respiratory rate and effort to evaluate ventilation and oxygen delivery; blood pressure if you can measure it to understand perfusion pressure to organs; skin color and temperature along with capillary refill to judge peripheral perfusion and circulatory status; pupil response as a quick neurologic check; and oxygen saturation if a pulse oximeter is available to directly gauge how well blood is being oxygenated and to determine if supplemental oxygen or faster evacuation is needed.

Each sign adds a piece of the puzzle: mental status can reveal CNS issues or declining consciousness; heart rate and rhythm reflect how well the heart is delivering blood; breathing patterns show how effectively oxygen is getting in and carbon dioxide is being removed; blood pressure gives a sense of overall circulation; skin signs and capillary refill hint at peripheral circulation and shock; pupil response can indicate neurologic problems; and oxygen saturation provides a direct measure of oxygenation. In the field, you’ll often have to prioritize and may not be able to obtain every measurement, but aiming to monitor this full set whenever possible maximizes your ability to detect deterioration early and make informed decisions about treatment and evacuation.
