RV failure from IWMI = weak pumping into the PA.
PA and wedge (PAOP) pressures will not rise; there is no backing up of blood or fluid to make them rise.
With the inefficient RV pump, there may be backup of blood into the RA and IVC, which would show in a high CVP reading.
As the right side of the heart is a low-pressure system, this is initially treated with IV fluids to maintain RV preload.
May see hypotension without rales (as opposed to LV failure--->rales), and bradycardia (may need pacemaker).
Google RV failure and/or IWMI hemodynamics.
Good on you, for going after certification!
