Critical Care Practicioner - By Jonathan Downham - January 14, 2015
"My good friend Gavin Denton has once again surpassed himself in analysing some of the evidence for the passive leg raise.
The bottom line.
- Half of patients who have signs of haemodynamic compromise will not be fluid responsive.
- Measuring the difference in stroke volume or cardiac before and after a passive leg raise is a highly sensitive and specific test of fluid responsiveness.
- The mode of cardiac output monitoring probably does not matter as it is the percentage change that is important rather than a specific number."
