RAD-57 placed on a finger is used to measure which parameter?

• A. Body temperature
• B. Carboxyhemoglobin
• C. Oxygen saturation
• D. Pulse rate

Answer: (B)

The device uses multi-wavelength spectroscopy to distinguish different forms of hemoglobin in the blood, so it can quantify how much carbon monoxide is bound to hemoglobin. This is what makes it a valuable tool for detecting and assessing carbon monoxide exposure. The RAD-57 is specifically designed as a pulse CO-oximeter to measure carboxyhemoglobin (and methemoglobin), not just the standard oxygen saturation. Because it’s specialized for CO-oximetry, it addresses the limitation of regular pulse oximeters, which can’t tell CO-bound Hb from oxyhemoglobin and thus can give misleading readings in CO exposure. It’s not a thermometer and it isn’t primarily used for measuring body temperature; while some devices display heart rate, the key function here is determining carboxyhemoglobin levels.
