Assessment of Volume Status
| Volume status | Reliable physical signs |
|---|---|
| Hypervolaemia | Elevated jugular venous pressure Oedema without hypotension |
| Euvolaemia | Absence of reliable signs of hypervolaemia or hypovolaemia |
| Hypovolaemia | Postural fall in systolic BP >20 mmHg (with BP measured after >2 min resting in the supine position, and then 1 min after standing) Postural increase in pulse rate >30/min (with pulse taken after >2 min resting in the supine position, and then 1 min after standing; count the pulse for 30 s and double the result) |
