ABSTRAK

Simulator tekanan darah biasa digunakan sebagai nilai referensi dalam mengevaluasi tensimeter otomatis (NIBP monitor). Penelitian sebelumnya menunjukkan bahwa simulator tekanan darah dapat dibuat dengan menggunakan micro air pump berbasis motor dc sebagai aktuator. Namun, hasil simulasi yang dihasilkan berbeda untuk setiap merek tensimeter. Hasil analisa menunjukkan bahwa laju inflasi dan deflasi yang berbeda mempengaruhi karakteristik simulasi. Studi ini bertujuan untuk mengembangkan firmware simulator baru berdasarkan nilai pulse width modulation (PWM) dan gradien inflasi-deflasi untuk meminimalkan pengaruh tersebut, sehingga simulator dapat memberikan hasil yang sama untuk berbagai jenis dan merek NIBP monitor. Validasi dengan simulator referensi dan evaluasi dalam kondisi statis dan dinamis menunjukkan simulator yang dikembangkan cukup andal untuk melakukan pemeriksaan awal, termasuk evaluasi pengulangan hasil tensimeter otomatis.

ABSTRACT

Blood pressure simulators are commonly used as reference values in evaluating NIBP (noninvasive blood pressure) monitors. Prior research shows that an NIBP simulator can be made using dc motor based micro air pump as the actuator. However, the simulator yield different results for different brands of NIBP monitor. The analysis result showed that inflation/deflation rates do affect the simulation’s characteristic. This research aims to develop a new simulator firmware based on pulse width modulation (PWM) values and rising-falling slope to minimize the corresponding effect so that the developed simulator could generate the same result for various types and brands of NIBP monitor. Validation using a reference simulator and evaluation in static and dynamic conditions showed that the developed simulator is reliable enough to do a quick pre-checks, including assessing the repeatability of NIBP monitors.
