  1. Values are mean ± SD or number
  2. Heart rate, noninvasive systolic and diastolic blood pressures were measured before radial arterial puncture and cannulation
  3. All radial artery diameters are measured at 1.5 cm-2.5 cm on the transverse stripes of the wrist. The measurement is performed during the systolic period in three different cardiac cycles, and the average value is finally taken
