Abstract

Hemodialisis adalah prosedur medis yang digunakan untuk menggantikan fungsi ginjal yang rusak. Selama dialisis untuk pasien gagal ginjal dapat muncul gelembung udara dalam darah. Detektor gelembung merupakan salah satu bagian penting dalam proses ini, karena detektor gelembung akan mendeteksi adanya bubble dalam aliran Venous Catheter. Kehadiran bubble dalam sistem vena dapat mengakibatkan kondisi syok atau henti jantung yang berpotensi fatal. Studi sebelumnya telah mengembangkan detektor microbubble menggunakan teknologi Photoelectric Infrared. Sebelumnya dalam memaksimalkan pembacaan dilakukan penyesuaian pancaran sinar infrared dalam memaksimalkan pancaran saja dan belum dilakukan kalibrasi dan pengujian menggunakan darah. Dilakukan pengujian menggunakan air, performa deteksi bubble setelah dilakukan kalibrasi meningkat dimana error yang dimilikin oleh sensor infrared 0,01060071, dan menjadi 0,00003964, sedangkan akurasi sensor 0,9 menjadi 0,99 dan presisi 0,85 menjadi 0,99. Hasil kalibrasi menggunakan air menunjukkan adanya peningkatan performa deteksi bubble. Kalibrasi sensor ini dilakukan dengan menggunakan metode logistik regresi dengan intercept dan slope yang didapat yakni 65,0197325226436 dan -0,06463164465137253. Pada pengujian menggunakan darah, didapat hasil pembacaan sensor memiliki penurunan performa pembacaan dimana presisi, 0,7158, akurasi 77,45 dan error sebanyak 0,2845. Hasil dari pengujian ini menunjukkan adanya penurunan performa saat pengujian menggunakan darah. Pengujian pada golongan darah yang berbeda (A, B, dan AB) menunjukkan hasil variatif. Darah golongan A memiliki performa yang cukup baik dengan error 0,041666667, akurasi 0,92, dan presisi 0,6. Namun, darah golongan B menunjukkan hasil pembacaan yang terus menerus 1, disebabkan oleh viskositas tinggi yang berbeda jauh dari darah A. Pada darah golongan AB, hasil kalibrasi menunjukkan error 0,073394495, akurasi 0,874, dan presisi 0,868. Hasil ini menegaskan bahwa performa deteksi bubble pada sensor infrared sangat dipengaruhi oleh viskositas medium. Kalibrasi dengan medium yang memiliki viskositas serupa penting untuk memastikan akurasi dan presisi pembacaan sensor.===========================================================================
Hemodialysis is a medical procedure used to replace damaged kidney function. During dialysis for kidney failure patients, air bubbles may appear in the blood. The bubble detector is an important part of this process, because the bubble detector will detect the presence of bubbles in the Venous Catheter flow. The presence of bubbles in the venous system can result in potentially fatal shock or cardiac arrest. Previous studies have developed microbubble detectors using Infrared Photoelectric technology. Previously, to maximize readings, adjustments were made to the infrared beam to maximize the beam only and calibration and testing using blood had not been carried out. Testing using water was carried out, the bubble detection performance after calibration increased, where the error of the infrared sensor was 0,01060071, and became 0,00003964, while the sensor accuracy was 0,9 to 0,99 and the precision was 0,85 to 0,99. The results of calibration using water show an increase in bubble detection performance. Calibration of this sensor was carried out using the logistik regression method with the intercept and slope obtained, namely 65,0197325226436 and -0,06463164465137253. In testing using blood, it was found that the sensor reading results had a decrease in reading performance, where the precision was 0,7158, the accuracy was 77,45 and the error was 0,2845. The results of this test show a decrease in performance when testing using blood. Testing on different blood types (A, B, and AB) shows varied results. Type A blood has quite good performance with an error of 0,041666667, accuracy of 0,92, and precision of 0,6. However, type B blood shows a continuous reading of 1, caused by the high viscosity which is very different from blood A. For type AB blood, the calibration results show an error of 0,073394495, an accuracy of 0,874, and a precision of 0,868. These results confirm that the bubble detection performance of the infrared sensor is strongly influenced by the viscosity of the medium. Calibration with a medium that has a similar viscosity is important to ensure the accuracy and precision of sensor readings.
