Heparinised saline may be used in flushing arterial lines, to prevent clotting and blockage of the line. [citation needed] When syringes are used to perform a saline flush, it is important that the syringe not be reused for multiple patients, even though direct contact with the patient does not normally occur. [2]
An arterial line is usually inserted into the radial artery in the wrist, but can also be inserted into the brachial artery at the elbow, into the femoral artery in the groin, into the dorsalis pedis artery in the foot, or into the ulnar artery in the wrist. [2]
Arterial blood pressure is most accurately measured invasively through an arterial line. Invasive arterial pressure measurement with intravascular cannulae involves direct measurement of arterial pressure by placing a cannula needle in an artery (usually radial, femoral, dorsalis pedis or brachial). The cannula is inserted either via palpation ...
Peripheral arterial disease is a blockage in the arteries that carry blood away from your heart. It usually develops in your legs. The strongest risk factors are diabetes and smoking.
Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation. Blood typically exits the wound in spurts, rather than in a steady flow; the blood spurts out in time with the heartbeat. The amount of blood ...
Arterial lines provide a constant monitor of blood pressure, as well as a method of obtaining samples for blood gas tests; central lines can also monitor blood pressure and provide blood samples, as well as provide a means to deliver medication and nourishment; fingerpricks (or heelpricks on small babies) are used to obtain blood samples for ...
Pulmonary arterial hypertension (PAH) is a serious condition that happens when the tiny vessels in your lungs narrow, resulting in high blood pressure. Normally, the pulmonary artery supplies ...
The arterial compliance - the amount of tension produced per stretch of arteries, decreases with age, and the stiffness of arteries increases with age. [3] The structural change in blood vessels causes the elderly to be more susceptible to hypertension, which leads to complications in arteries, the heart and even the brain.
