Illustration of an arterial catheter inserted in the left radial artery and covered with a dressing Arterial catheter (Seldinger technique) Arterial catheter (Punktion technique) An arterial line (also art-line or a-line ) is a thin catheter inserted into an artery .
The first step is that crystalloid is flowing from the arterial line into the transfer bag. [12] And then autologous blood flows through the arterial line and filter after the placement of arterial cannulae. [12] The second step is crystalloid prime in the venous reservoir and oxygenator is replaced by blood through pressure gradients. [12]
The arterial pressure points In situations where direct pressure and elevation are either not possible or proving ineffective, and there is a risk of exsanguination , some training protocols advocate the use of pressure points to constrict the major artery that feeds the point of the bleed.
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.

The bag inflates with room air, or it can be attached to bottled oxygen. The optimal use of the BVM is with two people, one who secures the mask to the patient's face ensuring a good seal between the patient's skin and the mask. The other rescuer squeezes the bag taking care to provide adequate volume without over ventilating the patient.
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch. [1]
The radial artery is a common site for the insertion of an arterial line, such as for blood pressure monitoring in an intensive care unit. It is also commonly used for cerebral angiograms for the treatment of cerebral pathologies, such as strokes, [ 7 ] cerebral aneurysms [ 8 ] It is selected because it is accessible, and because of the low ...
The passage of the catheter may be monitored by dynamic pressure readings from the catheter tip or with the aid of fluoroscopy. The standard pulmonary artery catheter has two lumens (Swan-Ganz) and is equipped with an inflatable balloon at the tip, which facilitates its placement into the pulmonary artery through the flow of blood. The balloon ...
