ABSTRACT
The continuous automatic pulse pressure variation (PPVauto) is a test that continuously and automatically measures the pulse pressure of the patients who need fluid therapy among the general anesthesia patients or artificial respiration patients for whom voluntary breathing is impossible during surgical procedure. The objective of this review is to evaluate the safety and effectiveness of PPVauto. The searches were conducted on eight Korean databases including KoreaMed, Medline, Embase, and Cochrane Library. Seven hundred thirty-seven literatures were searched, and total of 20 studies were included for this review. On the basis of current data, we recommend that PPVauto is safe and effective test for patients who need fluid therapy among the general anesthesia patients or artificial respiration patients for whom voluntary breathing is impossible during surgical procedure.
