Pulse Wave Features and Fluid Metrics from 79 Hemodialysis Sessions

817 pulse wave measurements from 24 hemodialysis patients link fluid overload and blood volume to arterial wave features. The data includes 28 distinct pulse wave features, such as stroke volume and reflection coefficient, measured every 15 minutes during dialysis sessions over five weeks. This supplementary material from a longitudinal cohort study was published on figshare under a CC-BY-4.0 license.

Use Cases

• Modeling associations between relative blood volume and cardiac function parameters like stroke volume and cardiac output.
• Investigating the influence of cumulative ultrafiltration volume on diastolic blood pressure and peripheral resistance.
• Analyzing within-patient correlations between pre-dialysis fluid overload and changes in systolic blood pressure and pulse wave velocity.

Strengths

• Includes 28 distinct pulse wave features derived from repeated measurements.
• Data is longitudinal, covering 79 hemodialysis sessions from 24 patients over five weeks.
• Associations are quantified with specific percentages, e.g., RBV was associated with 64% of the measured PWFs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The cohort of 24 patients is relatively small for broad generalization.
