🫁 Diuretic Fluid Management & Daily Weight Simulator

Establishing a Stable Dry Weight Baseline

Dry weight anchors every later comparison in the monitoring plan.

• ~78 kg: Baseline weight (stable euvolemic reading)
• AM: Weigh-in time (same time daily)
• Fixed: Scale type (same scale each day)
• 40 mg: Starting dose (furosemide, once daily)

Why dry weight matters

A consistent dry weight baseline makes small daily shifts meaningful.

Daily Weight Monitoring Routine

Small daily fluctuations are logged and reviewed for trend direction.

• 14 days: Monitoring window (rolling log period)
• ±0.5 kg: Normal daily swing (expected variation)
• Diary / app: Log method (patient self-report)
• Daily: Review cadence (patient self-check)

Building the trend line

Routine daily entries reveal drift before symptoms appear.

Weight Gain Threshold Detection

A defined trigger separates normal noise from true fluid retention.

• +2 kg/2d: Alert threshold (standard HF action-plan cutoff)
• +1 kg: Single-day flag (early watch level)
• Call/notify: Action (clinician contacted)
• Low: False-alarm rate (with consistent technique)

Setting the trigger line

The +2kg/2-day rule is a widely used self-management cutoff.

Furosemide Dose Adjustment

Crossing the threshold prompts a predefined dose increase step.

• +40 mg: Typical step-up (per action plan)
• 80–160 mg: New dose range (titration ceiling)
• 48–72 h: Reassessment (after dose change)
• K+/Na+/Cr: Electrolyte check (with dose escalation)

Titration logic

Higher loop diuretic dose targets the excess retained fluid.

Volume Status Stabilization

Weight settles back near baseline and the dose steps back down.

• Dry weight: Target weight (return to baseline)
• Step-down: Dose taper (once stable)
• Weekly: Follow-up (maintenance check)
• Euvolemia: Outcome goal (no readmission)

Returning to maintenance

Stable daily weights confirm the fluid overload has resolved.

Daily weight is a simple, low-cost early-warning signal for fluid shifts.
