Invasive hemodynamic monitoring using a Swan-Gantz catheter is essential in the optimal management of patients in shock or those suffering post-shock sequelae. Which of the following physiologic characteristics are associated with the various forms of shock?
A. Hypovolemic shock: Decreased pulmonary capillary wedge pressure (PCWP), decreased cardiac output, increased systemic vascular resistance (SVR)
B. Cardiogenic shock: Increased PCWP, decreased cardiac output, decreased SVR
C. Septic shock (hypodynamic): Decreased cardiac output, increased SVR
D. Neurogenic shock: Decreased PCWP, increased cardiac output, decreased SVR
