Assistant Professor, Departments of Emergency Medicine and Pediatrics, State University of New York Health Science Center at Syracuse Tympanic thermometry using infrared thermography technology offers a noninvasive, rapid temperature measurement tool which may be useful for selected intensive care unit (ICU) patients. Multiple comparisons of pulmonary artery catheter (PAC), rectal (R), and tympanic membrane (TM) temperatures were performed in nine adult ICU patients using PAC temperature as the gold standard. The correlation between R (r=0.93) and PAC was significantly better than TM (r=0.74) temperatures. However, PAC (37.2 ± 0.06°C ; mean ± SEM) and TM (37.1 ± 0.08°C) temperatures were not significantly different, whereas R (37.6 ± 0.07°C) was significantly warmer than both (P <.05). Differences between either R (+0.4°C) or TM (-0.1 °C) and PAC temperatures were consistent over selected ranges between 35°C and 40°C. The performance of TM and R was similar in the ability to predict PAC temperatures.
