Does pulse pressure variation accurately predict fluid responsiveness in patients during general anesthesia?
While pulse pressure variation has strong predictive value for fluid responsiveness, it remains inconclusive in about a quarter of patients under general anesthesia.
Despite a strong predictive value, PPV may be inconclusive (between 9% and 13%) in approximately 25% of patients during general anesthesia.
