Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Anesthesiologists need to understand the specific difference between dorsalis pedis arterial(DPA) pressure and the more commonly used radial arterial(RA) pressure When blood pressure monitoring at DPA. Generally, the systolic blood pressure measured in DPA is significantly higher than that in RA, with little difference of diastolic blood pressure and mean artery pressure in two sites. However, there is no specific study on the difference between them, and it is not clear how the diagnosis and treatment threshold should be adjusted when relying on DPA blood pressure measurement to guide treatment. The intraoperative blood pressure of patients is in the normal range in most cases. The purpose of this study is to analyze the correlation of different blood pressure stratification (RASBP90-109mmHg,110-129mmHg,130-149mmHg) of DPA-RA in the normal range to understand the correlation of DPA-RA in different blood pressure ranges, to provide a reference for clinical decision-making and hemodynamic management.
