Radial artery puncture
Radial Artery Puncture
Radial artery puncture (pronunciation: /ˈreɪdiəl ˈɑːrtəri ˈpʌŋktʃər/) is a medical procedure that involves the puncturing of the radial artery, typically for the purpose of obtaining an arterial blood sample or for arterial blood gas (ABG) analysis.
Etymology
The term "radial artery puncture" is derived from the Latin "radius" meaning spoke of a wheel or ray, and the Latin "arteria" meaning windpipe, artery. The term "puncture" comes from the Latin "punctura" meaning a pricking or puncturing.
Procedure
The radial artery puncture is performed using a needle and syringe. The healthcare professional first locates the radial artery, which is found on the thumb side of the wrist. The area is then cleaned and the needle is carefully inserted into the artery. Once the arterial blood is drawn, the needle is removed and pressure is applied to the puncture site to stop any bleeding.
