Current online hemodiafiltration devices can be used to determine the absolute blood volume in clinical practice using the dialysate bolus method. Most of publications on this method have focused on preventing intradialytic complications. The influence of absolute blood volume on long-term prognosis has not been reported yet.

- Conduction system pacing (CSP) is being explored as a better option than traditional right ventricular (RV) pacing, but previous studies have been limited.
- This large study analyzed Medicare data to compare outcomes between patients using CSP and those with dual-chamber (DC) RV pacing, separating CSP patients into two groups: left bundle branch area pacing (LBBAP) and His bundle pacing (HBP).
- Results showed that CSP patients had significantly lower rates of heart failure hospitalizations and all-cause mortality compared to DC RV patients, with LBBAP patients experiencing fewer complications than HBP patients.
Background: The rate and the duration of ultrafiltration (UF) are considered the most important factors to affect vascular refilling. The aim of the study was to investigate whether a UF profile could improve the vascular refilling.
Methods: Dialysis was delivered by a machine providing feedback control of ultrafiltration rates.
Absolute blood volume can be calculated from the increase in relative blood volume after an infusion of a well-defined volume bolus of ultrapure dialysate into the extracorporeal circulation. Several working groups have applied this method in research and clinical practice. A critical analysis of differing blood volume data between working groups revealed methodologic problems of the measurement procedure and some important technical aspects.
