Replacement of lost fluids is based on clinical estimation of the intravascular volume.
Clinical estimation is relied upon because objective measurements of fluid compartment volumes are not practical in the clinical environment.
Intravascular volume can be estimated using:
- Patient History
Factors include recent oral intake, persistent vomiting or diarrhea, gastric suction, significant blood loss or wound drainage, intravenous fluid and blood administration, and recent hemodialysis
- Physical Examination
- Laboratory Evaluation
- Hemodynamic Measurements
