“…Hypervolemia, hypematremia, and hyperkalemia are important risk factors for their morbidities and mortalities. In previous studies, 3,4,5,27,28 the relationship between hypervolemia and malnutrition was regarded to be the key indicator of predisposition to hypertension in HD patients, further preventing the progression of cardiovascular event rate. During dialysis treatment, inadequate fluid removal and blood volume ultrafiltration control or fluid volume imbalance provoked hypotension, associated with clinical symptoms for nursing decreases SBP by greater than 20 mmHg or decreases mean arterial pressure by 10 mmHg.…”

“…Inadequate dry weight results in a higher level of blood pressures, while prolonged symptoms lead to restructuring of the heart function and induction of heart failure and arrhythmias. 4,5 Therefore, maintaining dry weight, adequate water volume control, blood pressure control, and reducing sodium concentration is important in postdialysis healthcare for dialysis patients. This study proposes a strategy to prevent hypervolemia and maintain envolemia/dry weight.…”

Maintaining adequate dry weight and fluid volume balance is an important issue for dialysis patients. Malnutrition and sodium intake are the primary factors that cause fluid volume imbalance and changes in body weights. Inadequate dry weight control results in higher levels of blood pressures and is related to various complications, such as volume overload, hypertension, congestive symptoms, and cardiovascular diseases. Moreover, inadequate fluid removal provokes hypotension during dialysis treatment. Thus, we propose an early warning tool based on fuzzy color reason analysis in predialysis healthcare for hypervolemia screening. The anthropometric method is a rapid, non-invasive, and simple technique for estimating the total body water. In this study, Watson standard formula is employed to estimate cross-sectional standard of total body water with the patient characteristics, including gender, age, height, and weight. In contrast to the experienced anthropometric formulas, Watson formula has less than 2% of margin errors and provides a criterion as a reference manner to estimate the total body water in patient's normal dry weight. In addition, inadequate dry weight and total body water controls will lead to higher blood pressures. The systolic blood pressure is also an indicator to evaluate pre-hypertension of 120-139 mmHg and hypertension of greater than or equal to 140 mmHg. Therefore, the levels of two indicators, total body water and systolic blood pressure, are parameterized with fuzzy membership grades to describe the normal and the specific ranges of undervolemia and hypervolemia. A color reason analysis utilizes a huesaturation-value color model to design a color perceptual manner for separating normal condition from hypervolemia or undervolemia. Normalized hue angle and saturation value provide a promising visual representation with color codes to realize the patients' diagnosis. Dialysis patients with hypertension demonstrated that the proposed model can be used in clinical applications. In addition, a healthcare chair is carried out to measure blood pressure and weight in predialysis. The proposed assistant tool integrates an electronic pressure monitor and an electronic weight monitor, and fuzzy color reason analysis is also intended to be established in an intelligent vehicle via a WiFi wireless local area network for cloud computing.

“…Inadequate attainment of dry weight ultimately results in higher levels of blood pressure. Often, more antihypertensive medication is added as a consequence [9]. Echocardiography can provide relevant information related to hydration status, besides assessment of end-organ damage, but is cumbersome, time-consuming, and requires specialized equipment and personnel.…”

Hypertension is one of the most common worldwide diseases. Is linked with increased morbidity and mortality and amplified costs to society; in this context, preventing and treating hypertension is an imperative public health challenge. Unidentified, clinically unapparent volume expansion is an important cause for hypertension. Optimization of fluid status was associated with an improvement in BP control, a substantial regression of the left ventricular mass index, arterial stiffness and better survival rate in several cohorts. Clinical assessment of hydration status is an inaccurate clinical science. Bioimpedance provides a noninvasive and reliable, simple, reproducible technology for diagnosing subclinical fluid accumulation. Several small studies and a recent meta-analysis performed in patients with resistant hypertension reported an improved BP control in the impedance treated group compared with the group of patients treated as per clinical judgment alone. A combined approach (using both sphygmomanometers and bioimpedance) and individualized antihypertensive treatment in hypertensive's patients it seems probable to improve BP control and possibly end organ damage. i 2014 S.

“…Both low and high ABI are associated with 78 increased mortality in patients on hemodialysis [7,12]. Since there is an interaction 79 4 between the autonomic nervous system and the vascular response [13], acute changes in 80 ABI during hemodialysis may be a result of the sympathetic response to ultrafiltration. 81 Given that high dialysate calcium (DCa) concentration is related to better 82 hemodynamic tolerability during hemodialysis, we hypothesized that higher DCa might 83 lead to a higher sympathetic activity, which may explain acute changes in ABI during 84 hemodialysis.…”

“…Cuffs were comfortably set in 116 place, adjusted to the arm above the cubital malleolus with the cuff directed towards the 117 brachial artery trajectory, and directed toward the trajectory of the posterior tibial artery. As shown in Table 2, there was a decrease in systolic and mean BP while on DCa between HRV and ABI [8][9][10]13], but also showing that this is also applicable in the 208 setting of ESRD patients on hemodialysis.…”
