<![CDATA[Background: Chronic kidney disease patients undergoing regular hemodialysis are at risk of developing cardiovascular complications, one of which is intradialytic hypertension. Blood flow velocity, or Quick of Blood (QB), during hemodialysis is thought to be related to fluctuations in patient blood pressure. Objective: This study aimed to analyze the relationship between blood flow velocity (Quick of Blood/QB) and the incidence of intradialytic hypertension in chronic kidney disease patients undergoing hemodialysis. Method: This was an analytical observational study with a cross-sectional approach. The study sample consisted of 74 respondents selected using a total sampling technique, namely patients who had undergone hemodialysis for more than one year. QB data were obtained from the hemodialysis machine monitor, while blood pressure was measured using a sphygmomanometer before and during hemodialysis. The relationship between the two variables was analyzed using the Kendall Tau correlation test. Results: The majority of respondents had a standard QB (200–300 ml/minute), totaling 63 respondents (85.1%), with a mean of 227.3 ml/minute. Most respondents experienced intradialytic hypertension, totaling 66 respondents (89.2%), with a mean increase in systolic blood pressure of 16.22 mmHg. Conclusion: The statistical test results showed a p-value of 0.053 (>0.05), indicating no significant relationship between QB and the incidence of intradialytic hypertension in chronic kidney disease patients. Hemodialysis nurses should continue to monitor patients' blood pressure regularly, even if QB is within the standard range, as intradialytic hypertension is thought to be more influenced by other factors such as age, duration of hemodialysis, and the patient's hemodynamic condition.]]>
