In this episode, we cover:
What a PAC is and what it measures (RA, RV, PA, PAOP, CO, SvO₂).
When to use it: refractory shock, advanced heart failure, pulmonary hypertension, complex perioperative cases.
Step-by-step placement and waveform interpretation.
Calculations: SVR, PVR, CI, SvO₂ — and how to apply them clinically.
Key benefits, limitations, and risks (arrhythmias, PA rupture, over-wedging).
Landmark trials: ESCAPE (2005), PAC-Man (2005), Sandham (2003), FACTT (2006).
How to integrate PAC data with echocardiography for patient management.
