研究概览
简要总结
Vein compressibility will be assessed after light pressure applied with the ultrasound probe. Vein compressibility will be graded as 3 (100% compressed), 2 (50-100 compressed), and 1 (less than 50% compressed). After baseline measurements were taken, a proximal tourniquet will be applied to mid-arm. Repeated measurements of depth, width, and compressibility will be taken one minute after the tourniquet was applied. Same measurements will be repeated again with second tourniquet applied 1 cm distal to the first tournique.
