* PCWP: Pulmonary Capillary Wedge Pressure; Normal = 6 - 12 mm Hg;
* jugular wave pattern
* Cardiac Output
* Shunt
* A-a gradient
* Compliance
* Sampling of Mixed Venous O2:
   - Shows changes in Arterial oxygenation as Cardiac Output changes;
   - Allows calculation of AVo diff and Shunt[Shunt: (for Respiratory Failure);
   - PVo2 < 30 mm Hg, prognosis is poor
