Causes of Generalized Edema - Differential Diagnosis Algorithm
Overfill (Increased renal sodium retention, Urine Na > 40meq/L)
Increased Interstitial Oncotic ... Decreased Capillary Oncotic
Pitting vs Non-Pitting Edema: Differential Diagnosis
For pitting edema: there's generally an issue with :
  ↑
pressure ↓ Plasma oncotic
Causes of Edema - Differential Diagnosis
Pitting Edema:
  ↑ Hydrostatic - Too Much Fluid
Pressure ↓ Oncotic
Conceptual Relationship between Volume Responsiveness and Volume Tolerance

Assessing for volume responsiveness would only tell you that
-decreased oncotic
Causes of Peripheral Edema - Differential Diagnosis
Increased Hydrostatic Pressure
 • Volume Expansion: Kidney failure, Pregnancy, Medication
blockers Decreased Oncotic
Causes of Pleural Effusion - Differential Diagnosis Algorithm
Exudative Effusion:
 - Pulmonary
     •
- Decreased Oncotic

Transudate - Hydrostatic
 • Congestive heart failure
 • Constrictive
Transudate - Oncotic
Drug-Induced Edema
Drug-induced edema is caused by many drugs & can coincide with or worsen pre-existing peripheral
