摘要

The transcutaneous pacer analyzer is used to verify the performance of transcutaneous pacers, which provide a temporary method of cardiac pacing during various clinical cardiac emergencies. Establishing a calibration procedure for the transcutaneous pacer analyzer is essential to ensure the accuracy and quality of performance verification of transcutaneous pacers. This paper presents the developed calibration methodology for a transcutaneous pacer analyzer, along with a systematic approach for the estimation of measurement uncertainty for important parameters such as pulse energy, pulse current, pulse width and pulse rate using a calibration setup traceable to national standards. The measurement uncertainty associated with these parameters is evaluated by considering various contributing factors. The expanded uncertainty evaluated for resistance at 50 Ω, pulse energy of 2.5–22.5 mJ, pulse current of 50–150 mA, pulse width of 20 ms and pulse rate of 1–3.5 Hz are ± 0.5 mΩ, ± (0.03–0.3) mJ, ± (0.2–0.4) mA, ± 0.02 ms and ± 0.01 Hz respectively. Such a comprehensive analysis on measurement uncertainty evaluation has not been reported so far.
