What fluid overload percentage is associated with poor outcomes?

Cumulative fluid overload >10% of body weight is associated with ARDS, AKI, prolonged MV, and increased mortality; target neutral to negative fluid balance after initial resuscitation; daily weight monitoring is essential.

What is pulse pressure variation (PPV) and its fluid responsiveness threshold?

PPV = (PPmax - PPmin) / PPmean × 100% over the respiratory cycle; PPV >13% predicts fluid responsiveness with ~80% sensitivity and specificity; only valid in fully ventilated patients without arrhythmias.

What is the passive leg raise test?

PLR: raise legs to 45 degrees for 1 minute; ≥10% increase in CO (measured by echo or Vigileo) predicts fluid responsiveness; can be done in arrhythmia and spontaneously breathing patients; CO increase must be measured, not just blood pressure.

Should crystalloids or colloids be used for ICU resuscitation?

Balanced crystalloids (Ringer lactate, Plasmalyte) are preferred over NS (0.9% NaCl) due to lower risk of hyperchloremic metabolic acidosis and AKI; albumin in sepsis if hypoalbuminemic; starch colloids contraindicated in sepsis (renal harm).

What is the FACTT trial approach to fluid management in ARDS?

Conservative fluid strategy (FACTT trial) in ARDS improved lung function, reduced MV days and ICU stay but did not improve mortality; daily diuresis targeting fluid neutral/negative balance after resuscitation phase is recommended.

ICU Fluid Balance and Cumulative Fluid Overload Calculator

Calculates ICU net fluid balance, cumulative fluid overload percentage (>10% BW associated with worse outcomes), and fluid responsiveness prediction from pulse pressure variation (PPV) and passive leg raise.

⚕ Clinical Disclaimer: These calculators are for educational and reference purposes only. Always verify results with qualified clinical judgment and current clinical guidelines. Do not use as a sole basis for medical decisions.

How It Works

Each component has a specific meaning:

Pulse pressure variation — The pulse pressure variation recorded for the scenario being assessed.
Passive leg raise — The passive leg raise recorded for the scenario being assessed.

Note: Interpret the icu fluid balance result against the thresholds and context described above.

How to Use

Enter the pulse pressure variation, passive leg raise for the scenario you are assessing. Calculates ICU net fluid balance, cumulative fluid overload percentage (>10% BW associated with worse outcomes), and fluid responsiveness prediction from pulse pressure variation (PPV) and passive leg raise. Use the icu fluid balance result to inform your calculation.
