经证实，在没有开胸或快速输注冷血的情况下，较低的食道温度读数将给出大脑温度的大致指示。鼻咽读数不太可靠，不应单独使用。中、上段食管的记录由于冷冻冷却而不能令人满意。为了确保精度大于± 1.0°C，需要直接进行脑内读数。4 cm深处的大脑通常比食道下部或鼻咽部稍热。更表面的读数可能会受到环境温度和外科手术的影响
It is confirmed that lower oesophageal temperature readings will give an approximate indication of the cerebral temperature in the absence of an open thorax or a rapid transfusion of cold blood. Nasopharyngeal readings are less reliable and should not be used on their own. Middle and upper oesophageal recordings are unsatisfactory because of ventilatory cooling. For an assured accuracy greater than ± 1.0°C, direct intracerebral readings are necessary. The brain at a depth of 4 cm is usually slightly warmer than the lower oesophagus or nasopharynx. More superficial readings may be affected by the ambient temperature and surgical procedures
