Abstract :

Fluid challenges are the first line of management in hypoperfusion, and low cardiac output situations. Some of these situations can be associated with left and right ventricular dysfunction, which would impair the hearts ability to handle the volume given. Traditional methods of volume measurement such as central venous pressure, pulmonary capillary wedge pressure, cannot assess whether there is a volume deficit, volume over load or normo volaemia. These measurements also cannot assess whether the patient can increase the cardiac output in response to a fluid challenge. Volume assessment can be done by measurement of the change in diameter of the superior vena cave during ventilation. To assess whether the cardiac output will increase in response to a fluid challenge, it is necessary to assess stroke volume variation, systolic blood pressure variation or pulse pressure variation in mechanically ventilated patients. When these are not possible passive leg rising is an alternative.
