Which two temperature monitors are considered best for reflecting core body temperature?

The most accurate indicators of core body temperature are found in areas that reflect the internal temperature of the body rather than external factors. Among the options provided, the distal esophageal and pulmonary artery monitors are regarded as more reliable for measuring core body temperature.

The distal esophageal temperature monitor is inserted into the esophagus and provides readings that closely correspond to core body temperature due to its proximity to the heart and the thoracic cavity. This makes it an excellent choice for assessing core temperature, particularly in settings like anesthesia and intensive care.

The pulmonary artery is another site that reflects core temperature closely, as blood pumped from the heart through this artery carries warm blood directly from the core organs. This method is often used in critical care settings to monitor patients' hemodynamic status and body temperature accurately.

On the other hand, skin and axillary temperature measurements tend to be influenced more by environmental conditions and peripheral factors, making them inadequate for accurately assessing core body temperature. Skin temperature can vary significantly based on exposure, clothing, and ambient temperature, while axillary temperatures are often lower than core body temperatures and can fluctuate based on external conditions as well.

Thus, when evaluating which monitors are best for reflecting core body temperature, distal esophageal and pulmonary artery options are ideal due
