of a PAC
Thus far, we have covered
invasive hemodynamic monitoring with arterial lines and CVP catheters. The Pulmonary
Artery catheter (PAC) is another invasive way to obtain hemodynamic measurements.
The purpose of this catheter
- Indirectly measure the
left ventricular end-diastolic pressure.
- Evaluate the hemodynamic
treatments and measure the patients hemodynamic status.
- Draw mixed venous blood
- Obtain central vascular
- Measure cardiac output.
There are certain indications
for using a PA catheter. They are:
- Conditions of shock such
as septic and hypovolemic shock.
- Evaluation of fluid volume
- Evaluation of cardiac
output in complex medical situations.
- Prophylactic insertion
for high-risk surgeries.
catheters are useful to measure cardiac output in complex medical situations
and evaluate fluid volume status in hypovolemic and septic shock.
