Arterial Catheterization Techniques

Arterial catheterization involves inserting a small tube, called a catheter, into an artery—usually in the wrist or groin—to directly access the bloodstream. This technique is used mainly for accurately measuring blood pressure continuously and drawing blood samples quickly. The procedure involves cleaning the area, numbing it with local anesthesia, and then carefully inserting the catheter into the artery with guiding tools. Once in place, the catheter allows healthcare providers to monitor vital signs closely and manage critical procedures efficiently. It’s a precise and controlled method that provides vital information for managing seriously ill patients.
