Like many things in the hospital, it comes down to your staffing model. Open ICU with surgeons and it could get wild when looking at a swan. But other than myself, my SICU has pretty much zero people who have any facility with a TTE probe (other than for a qualitative assessment of whether the pt is at cardiac standstill). Even worse are the few who have taken a basic POCUS course who slap the probe on the chest for 5 seconds and go "oh yea looks good" even though they only looked at one view and have no idea what the depth marker or normal RV/LV dimensions or a VTI or IVC plethora are.
Regardless, say even if I am staff, the swan is still helpful in certain situations. If a pt is borderline hypoperfusing, it is the gold standard for cardiac output. If the pt has concomitant pHTN, cant beat actually knowing the PAs vs derived TR RVSP. And more and more data keeps coming out validating the utility of PAPi and CPO. Above all, it is a continuous monitor, not a spot check, and it doesn't suffer the same interobserver variability as echo.
Furthermore, at some point I gotta go home (I am an anesthesiologist after all) and I'll have to rely on the bedside nurse or a resident. If the pt's UOP has dropped off, I can't exactly go tell the nurse to get me three views of the RV and tell me whether the function is now severely reduced from moderately reduced, can I? OTOH, nurse can tell me over the last 3 hrs the sPAP down 10, dPAP up 10, CI now 1.8, CVP rising, and remotely I have gained the information I need.
