We read with interest the recent article by Monge Garcia and colleagues . We have two comments regarding this interesting physiological study.
Which means that SVV (%) ≈ pulse pressure variation (PPV; %) for FloTrac™.
In conclusion, we believe that dynamic Ea predicting arterial pressure response to volume loading in preload-dependent patients is an interesting physiological concept. However, this demonstration cannot be achieved without taking into consideration the impact of PPV/SVV sampling.
