Abstract
Deep Vein Thrombosis (DVT) merupakan kondisi terbentuknya trombus pada vena dalam yang dapat mengganggu aliran balik vena pada ekstremitas bawah dan berpotensi menimbulkan emboli paru apabila trombus terlepas menuju pembuluh darah paru. Salah satu metode profilaksis mekanik yang digunakan untuk membantu mengurangi stasis vena adalah Intermittent Pneumatic Compression (IPC), yaitu pemberian tekanan eksternal secara berkala pada tungkai. Penelitian ini bertujuan merancang dan membangun prototipe IPC tiga chamber untuk tungkai bawah berbasis ESP32 serta mengevaluasi kemampuan teknisnya dalam mencapai tekanan target, menjalankan kompresi sekuensial, mempertahankan tekanan selama fase hold, dan mendokumentasikan sesi kompresi secara digital. Penelitian menggunakan metode Research and Development yang meliputi perancangan, implementasi, kalibrasi, dan pengujian prototipe pada manekin. Prototipe dilengkapi OLED sebagai antarmuka lokal serta web-dashboard berbasis Firebase Realtime Database untuk menampilkan tekanan, status sistem, dan catatan sesi secara periodik. Pengujian tekanan dilakukan pada setpoint 30, 40, 50, dan 60 mmHg dengan 60 siklus pada setiap setpoint. Setiap siklus menghasilkan data tekanan puncak CH1, CH2, dan CH3 sehingga diperoleh 720 data tekanan puncak. Hasil kalibrasi menunjukkan hubungan linear antara pembacaan sensor dan manometer dengan nilai R² sebesar 0,9936-0,9973. Seluruh kombinasi setpoint dan chamber menghasilkan tekanan puncak rata-rata dengan error absolut tidak melebihi ±5 mmHg terhadap setpoint. Simpangan baku tekanan puncak berada pada rentang 0,65-1,36 mmHg. Penurunan tekanan selama fase hold berada pada rentang 0,79-1,02 mmHg, sedangkan koefisien variasi tekanan puncak sebesar 1,47-3,37%, yang menunjukkan bahwa variasi antar-siklus relatif kecil. Sistem juga mampu menjalankan urutan kompresi CH1-CH2-CH3 dan mencatat ringkasan sesi melalui web-dashboard dan session log. Dengan demikian, prototipe berhasil mengintegrasikan kompresi sekuensial, kendali tekanan, dan pemantauan digital untuk mendukung evaluasi teknis sistem. Karena pengujian dilakukan pada manekin, hasil penelitian belum dapat digunakan untuk menyimpulkan efektivitas klinis maupun respons hemodinamik pada manusia.

Deep Vein Thrombosis (DVT) is characterized by thrombus formation in the deep veins, which can impair venous return in the lower extremities and potentially lead to pulmonary embolism if the thrombus detaches and travels to the pulmonary vasculature. One mechanical prophylaxis method used to help reduce venous stasis is Intermittent Pneumatic Compression (IPC), which applies periodic external pressure to the limbs. This study aimed to design and develop an ESP32-based three-chamber IPC prototype for the lower limb and evaluate its technical performance in reaching target pressures, performing sequential compression, maintaining pressure during the hold phase, and digitally documenting compression sessions. A Research and Development method was employed, comprising prototype design, implementation, calibration, and testing using a mannequin. The prototype was equipped with an OLED as a local interface and a Firebase Realtime Database-based web dashboard to periodically display pressure, system status, and session records. Pressure testing was conducted at setpoints of 30, 40, 50, and 60 mmHg, with 60 cycles at each setpoint. Each cycle generated peak-pressure data for CH1, CH2, and CH3, resulting in a total of 720 peak-pressure data points. Calibration results showed a linear relationship between the sensor readings and the manometer, with R² values ranging from 0.9936 to 0.9973. All setpoint-chamber combinations produced mean peak pressures with absolute errors not exceeding ±5 mmHg relative to their respective setpoints. Peak-pressure standard deviations ranged from 0.65 to 1.36 mmHg. Pressure decreases during the hold phase ranged from 0.79 to 1.02 mmHg, while peak-pressure coefficients of variation ranged from 1.47% to 3.37%, indicating relatively low inter-cycle variability. The system was also able to perform the CH1-CH2-CH3 compression sequence and record session summaries through the web dashboard and session log. Therefore, the prototype successfully integrated sequential compression, pressure control, and digital monitoring to support technical system evaluation. Because testing was conducted using a mannequin, the findings cannot yet be used to establish clinical effectiveness or hemodynamic responses in humans.
