Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: With ultrasound guidance
In this group of patients, ultrasound guidance will be used when drawing blood from the radial artery.
Procedure: Artery puncture with ultrasound guidance
Ultrasound device will be used to locate artery for puncture.
Active Comparator: Without ultrasound guidance
In this group of patients, no ultrasound guidance will be used when drawing blood from the radial artery.
Procedure: Artery puncture without ultrasound guidance
Blood drawn from radial artery according to conventional procedure, without ultrasound guidance.
