SUMMARY
1. CVP at RA ~4.6 mmHg & fluctuates with respiration.
2. High CVP reading may be caused by anything that puts strain on the right heart: a rapid fluid bolus, pulmonary embolism, tension penumothorax, cor pulmonale.
3. Inspiration generate negative thoracic pressure & helps venous return.
4. Pressure in the subclavian vein, as it crosses the first rib, is positive above atmostpheric pressure, when lying down.
