Benefits of systems using a CVAD include the ability to administer vasopressors and caustic medications,monitor central venous pressure, and obtain specimens for intermittent central venous oxygen saturation
(ScvO2) analysis. Drawbacks include the delay in starting therapeutic hypothermia while the specialized
catheter is placed; risks of catheter related injury, infection, or thrombosis; and the inability to place this catheter in certain settings such as an ambulance. Although invasive methods such as these systems can be expensive compared to noninvasive methods, the cost may be offset by the decrease in nursing time and complications, and improved patient
outcomes.
