Interpret hemodynamic profiles from pulmonary artery (Swan-Ganz) catheterization. Warm-Wet (high PCWP, normal CI): decompensated HF without shock. Cold-Wet (high PCWP, low CI): cardiogenic shock. Cold-Dry (normal/low PCWP, low CI): hypovolemia or RV failure. Warm-Dry (normal PCWP, normal CI): compensated.
