Healthy volunteers

Accepted

Inclusion Criteria: * Age between 18 and 85 years * Palpable pulses in both the distal radial artery and conventional radial artery * All patients signed informed consent forms prior to procedure Exclusion Criteria: * Ultrasound assessment of the distal radial artery diameter ≥2.0mm or \<1.0mm * Height ≥185.0cm * Patients with acute ST-segment elevation myocardial infarction, cardiogenic shock, or hemodynamic instability * Contraindications for puncture of the distal radial artery * Patients with Raynaud's syndrome * Patients with coagulation disorders or hematologic diseases * Patients currently enrolled in other clinical studies

Primary outcome measure(s)

Distal radial artery occlusion(dRAO) — 24 hours postoperatively.
The dRAO is defined as the absence of blood flow in the distal radial artery assessed by the doppler ultrasound.
