Jun 29, 2015 · The arterial pressure wave (which is what you see there) is a pressure wave; it travels much faster than the actual blood which is ejected. It represents the impulse of left ventricular contraction, conducted though the aortic valve and vessels along a fluid column (of blood), then up a catheter, then up another fluid column (of hard tubing) and finally into your Wheatstone bridge transducer ...
Arterial line placement is a cornerstone in managing critically ill patients in the intensive care unit and the operating suites. It provides real-time arterial blood pressure monitoring and facilitates frequent blood gas measurements.
Arterial lines are connected to a bedside monitor to continuously display both the waveform and pressure from within the artery (Image 2). Image 2: Arterial waveform on beside monitor (red) prevent blood from clotting in an arterial catheter, a slow continuous infusion of fluid is run into the catheter (at 2-3 ml per hour).
basic principles enables arterial lines to be used safely in these settings. Indications The indications for a radial arterial line are: 1. Continuous, beat-to-beat blood pres-sure measurement. Examples include patients on the intensive care unit (ICU) requiring inotropic support, or patients with severe cardiovascular dis-
Why is an arterial line used? An arterial line is used to: Get a constant blood pressure reading. An arterial line is more accurate than a blood pressure cuff. The line constantly sends your blood pressure reading to a monitor. That means your medical team can see it easily. Take blood samples to measure the oxygen and carbon dioxide in your blood.
Aug 1, 2022 · Arterial lines are a useful device in a variety of clinical settings for the medical team. Arterial lines, or "A-lines," consist of a small catheter connected to a transducer that allows real-time blood pressure and hemodynamic monitoring of patients along with easy access for blood gases and other labs for critically ill patients.
The use of automated noninvasive blood pressure devices has diminished the use of arterial catheters simply for pressure monitoring. However, these catheters are beneficial in unstable patients who require minute-to-minute pressure measurement and in those requiring frequent arterial blood gas sampling.
