Overview
Brief Summary
The investigators designed a study to assess whether there were any blood flow indexes change before and after radial artery puncture with doppler ultrasonography
Detailed Description
The investigators designed a study to assess whether there were any blood flow indexes change before and after radial artery puncture with doppler ultrasonography.The indexes include Arterial Diameter,Peak Systolic Velocity,End Diastolic Velocity,Resistive Index,Pulsatility Index,Systolic/End Diastolic Ratio,Time AverageMean Velocity and Blood Flow.
