食道、直肠、鼓膜和中心血液温度，即，肺动脉和主动脉弓，记录在医源性全身热疗治疗晚期恶性转移癌的三个病人。主动脉温度紧随肺动脉温度变化，平均延迟时间为27 s。食管温度较鼓膜温度能更快、定量地反映肺动脉温度的变化（平均滞后时间为80 s）。在稳定状态下，鼓膜温度始终低于心脏的血液温度。因此，食管温度是反映中心血温度的较好指标。此外，食管温度的测量比鼓膜温度更容易和安全。
Esophageal, rectal, tympanic, and central blood temperature, i.e., pulmonary artery and aortic arch, were recorded in three patients during iatrogenic whole-body hyperthermia for the treatment of advanced malignant metastatic cancer. Aortic temperature closely followed changes in pulmonary arterial temperature, with an average delay time of 27 s. Esophageal temperature reflected quantitatively and more quickly (avg lag time, 80 s) the temperature changes in the pulmonary artery than tympanic membrane temperature. Tympanic temperature was consistently lower than the blood temperature of the heart during steady state. Therefore it is suggested that esophageal temperature is a preferable index of central blood temperature. Additionally, measurement of esophageal temperature can be made more easily and safely than tympanic membrane temperature.
