Using square were test, dynamic responses were measured of five kinds of blood pressure monitorning sets.As results of measurements, one kind of them had lower natural frequency than 11 Hz and had inadequate dynamic response. And 47% of another one kind of them showed overdamping on dynamic response during measurments. The other three kinds of them had higher than 19 Hz in the natural frequency and shoewd adequate dynamic responses by elimination of air bubbles from sets and filling the space between the transducer side membrane and the diaphragmdome with waterdrops. Therefore, they are quite useful in clinical monitorning, when air bubbles are eliminated from sets and the diaphragm dome are connected with waterdrops to the transducer side membrane. We concluded that, it is necessary to use the blood pressure monitorning sets which have adaquate dynamic response and important to make sure the dynamic response during measurements.
