Arterial lines, commonly referred to as “A-lines,” are a type of catheter that is inserted into a patient’s artery for more accurate and precise blood pressure monitoring. The arterial line is connected to a transducer that will transmit a pressure waveform and its corresponding values to a monitoring system.
