Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits

Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits

OBJECTIVE: To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation. INTRODUCTION: PPV is largely used for early identification of cardiac responsiveness, especially when...
