The relationship between blood flow rate and changes in blood pressure of patients during hemodialysis in Central Java, Indonesia

Abstract

Chronic Kidney Disease (CKD) is a disease that causes the kidneys to be unable to function or work again according to their function. One of the therapies that are often used by CKD patients is hemodialysis (HD) machines. Hemodialysis is a substitute for damaged kidney work. A HD machine has a Blood Flow Rate (BFR) arrangement to control the blood flow according to the patient's condition. This research aimed to determine the relationship between blood flow rate and changes in blood pressure (BP) of patients during hemodialysis. This study was conducted in the HD room of RSUP Dr Soeradji Tirtonegoro Klaten, Central Java, Indonesia. The type of research was quantitative non-correlational experiments with a cross-sectional approach. BFR was measured and monitored the speed on HD machines. Change of BP was measured before and intra-HD (2 hours of HD process started) with the digital sphygmomanometer. The study population was CKD patients in the HD process. The sample was 65 peoples. The sampling technique used Accidental Sampling and data analysis used the Spearman Rank. The majority of the BFR was 191-220 mL/minute, and the majority of respondents experienced decreased BP. Bivariate test results obtained P-value = 0.884 (p>0.05). There was no relation between the blood flow rate of HD machine and change of patient BP in hemodialysis process.
