An arterial line (also art-line or a-line) is a thin catheter inserted into an artery. It is most commonly used in intensive care medicine and anesthesia to monitor blood pressure directly and in real-time (rather than by intermittent and indirect measurement) and to obtain samples for arterial blood gas analysis.

Orthogonal arterial catheter
An orthogonal arterial catheter preferably includes a hub and a cannula. The hub preferably protects the cannula from potential kinking and shearing forces because the cannula upon exiting a patient's body enters the hub. The hub preferably provides a passageway through which the hose travels to a connector piece. The connector piece preferably attaches the device to a fluid line such as an arterial line transducer. In addition, the hub preferably includes a port that provides a channel through which a guide wire or a needle may gain access to the cannula. The hub also may include appendages extending from it to suture to the patient.
