This report was conducted to quantify the pulse/respiration ratio and set up the normal range of wan-maeck(緩脈). In order to objectify the pulse diagnosis and use as basic clinical index of Cold-Hot diagnosis, we developed the hardware and software for detection and interpretation of pulse/respiration ratio, pulse/expiration ratio, pulse/respiration ratio, inspiration time, expiration time, respiration frequency, respiration time, duration of one pulse and pulse and pulse rate per minute, The results were as follows; pulse/respiration ratio is $4.30{pm}1.03$ times, pulse/respiration ratio is $1.60{pm}0.32$ times, pulse/respiration ratio is $2.37{pm}0.75$ times, inspiration time is $1.35{pm}0.20$ sec, expiration time is $1.89{pm}0.39$ sec, respiration frequency is $17.16{pm}3.49$ times/min, total respiration time is $3.63{pm}0.71$ sec, duration of a pulse is $0.86{pm}0.15$ sec, pulse rate is $71.51{pm}12.30$ times/min.
