Please let me know if there is a role for central venous catheter in invasive hemodynamic monitoring?
Yes. Mandatory for most invasive monitoring. Very common, don't worry!
Occasionally. Invasive hemodynamic monitoring was much more en vogue 2-3 decades ago in the management of preeclampsia. Nowadays, most cases can be managed without it and CVP measurement is only rarely used in an ICU setting for preeclampsia complications such as pulmonary edema.
Rarely any more. CVP is falling out of favor as a way to manage fluids and volume status. It is only helpful when it rises very high, and is associated with significant risks in its placement and application. Pulse pressure variation (ppv) and stroke volume variation (svv) are less invasive ways to manage fluids and better reflect the response of the heart to changes in hydration.
