dynamic fluid response is used during management of shock

2. Dynamic fluid response
By
Momen Ali Khan

3. Definition
Dynamically determination of shock status
by the cardiovascular response ( heart rate,
blood pressure, CVP) by rapid administration
of fluid bolus.

4. Rapid administration
Rapid administration of fluid bolus means
administration 0f 250 to 500 ml fluid over
5 to 10 minute.

5. Patient condition
After rapid administration of fluid patient
can divide into-
Responders
Transient responders
Non-responders

6. Responders
Improvement in patient cardiovascular status which is
sustained.
Significance
These patients are not actively losing
fluid but require filling to a normal
volume status.

7. Transient responders
Have an improvement which then
reverts to the previous state over the next
10–20 minutes.
Significance
These patients have moderate ongoing
fluid losses (either overt haemorrhage or
further fluid shifts reducing
intravascular volume).

8. Non-responders
Are severely volume depleted and are
likely to have major ongoing loss of
intravascular volume, usually through
persistent uncontrolled haemorrhage.
