“…This research was compared with the research of Nico Antonio Santoso et al who conducted research on the NIBP simulator which had a deficiency in the 60/30 setting with an error of 6.67%, whereas in this study at the 60/30 setting the resulting error was 5.64% which is smaller than Antonio's research [15]. According the research by A Darwongso et al, a blood pressure simulator was developed using the MPX5100 pressure sensor, while in my research using the MPX5050 pressure sensor where the resulting values are more accurate [17].…”

“…However, it is important to acknowledge the limitations of this study, as it still exhibited an error rate of 6.67% specifically at the preset blood pressure level of 60/30. While the use of a micro air pump and pressure sensor represents a notable advancement in the methodology, the observed error suggests the presence of inaccuracies or imprecisions in the measurement process [15] [16]. Then in 2019, A Darwongso et al, conducted a study entitled Blood Pressure Simulator: Minimizing the Effects of Inflation and Deflation Rates on Oscillation Simulations.…”

Accurate monitoring of NIBP (Non-Invasive Blood Pressure) parameters using vital sign monitors is crucial for patient care. Therefore, calibration of vital sign monitors is essential to ensure their safety and reliability. The purpose of this study is a vital sign simulator was developed, integrating ECG and NIBP parameters with a TFT Nextion display, to calibrate ECG and NIBP readings on vital sign monitors. The system utilized the Arduino Mega 2560 as the central controller and the MPX5050GP sensor for NIBP measurement and motor pump control. The NIBP parameters were measured at two settings: 60/30 and 80/50. The results showed a maximum systolic error of 3.5% and a diastolic error of 5.6% for the NIBP setting of 80/50. The largest standard deviation value of 2.05 was observed at the NIBP setting of 60/30. The highest uncertainty value of 0.5 was also found in the NIBP 60/30 setting. The obtained data indicated stable module readings within the acceptable threshold for vital sign monitor calibration. The developed vital sign simulator offers a reliable means of calibrating NIBP parameters, enabling accurate blood pressure measurements. Further research and refinement can be conducted to enhance the system's precision and expand its capabilities for calibration of additional vital sign parameters. By ensuring accurate calibration, healthcare professionals can rely on vital sign monitors for effective patient monitoring and diagnosis.

“…Namun untuk memberikan hasil yang sama, diperlukan program (firmware) simulasi berbeda untuk tiap merek. Ini berbeda dari pengujian dengan simulator NIBP komersial, yang menghasilkan hasil yang sama terlepas dari semua jenis atau merek monitor NIBP (Santoso & Ughi, 2017).…”

“…Gagasan dari metode pada program yang digunakan oleh kedua penelitian tersebut di atas adalah dengan menemukan beberapa target osilasi untuk tiap nilai tekanan tertentu (Dewanto, 2016) (Santoso & Ughi, 2017). Ilustrasi pada Gambar 1 menjelaskan bagaimana nilai selisih ditentukan dari suatu grafik osilasi.…”

“…Hasilnya kemudian dibandingkan untuk mengevaluasi performa simulator yang dirancang. Perangkat keras yang digunakan merupakan perangkat keras yang sama yang digunakan oleh dua penelitian sebelumnya, (Dewanto, 2016& Santoso, 2017 Prinsip kerjanya secara singkat adalah sebagai berikut, cuff (manset) NIBP monitor yang akan dievaluasi, disambungkan dengan air splitter, sehingga tekanan udara yang dipompa oleh NIBP monitor akan terhubung dengan simulator NIBP. Pada simulator NIBP, jalur tekanan udara dibagi lagi untuk dihubungkan ke sensor tekanan dan micro air pump.…”

ABSTRAKSimulator 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.Kata kunci: NIBP monitor, PWM, NIBP simulator, gelombang osilasi, lajuinflasi, laju deflasi ABSTRACTBlood 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.Keywords: NIBP Monitor, PWM, NIBP Simulator, Oscillometric Waveform, Inflation Rate, Deflation Rate
