PPV for Predicting PIH in the Elderly
NCT07166562 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 86
Last updated 2025-09-10
Summary
The purpose of this observational study is to investigate the predictive power of pulse pressure variability during forced inhalation(PPVfi) on the occurrence of hypotension in elderly patients after induction of general anesthesia. The main question it aims to answer is:
Can the PPVfi predict the occurrence of hypotension in elderly patients after induction of general anesthesia? By recording the PPV of patients during forced inhalation before anesthesia induction, with the incidence of hypotension as the state variable and PPV as the test variable, the area under the ROC curve was calculated to determine the optimal threshold, sensitivity, and specificity of PPV.
