Excerpt

Pulse pressure respiratory variation (PPV), which is the difference between the maximal and minimal arterial pulse pressure values after each positive-pressure breath, is largely used for early identification of hypovolemic status. Increased PPV observed in hypovolemia results from exaggerated respiratory variation in transpulmonary blood flow that results in corresponding left ventricular preload variations during respiratory cycles. Hence, any modulations that affect the left ventricular preload would influence PPV. …
