Arterial pulsation can be simulated via the manual hand bulb to differentiate between arteries and veins via ultrasound. The optional fully integrated automated pump system can be included for additional ease. The veins in the central line mannequin are also compressible using mild pressure while the arteries remain uncompressed. Vessel identification is designed easy immediate positive fluid flow of the vein versus artery. The venous system is prefilled with blue fluid and the arterial system is prefilled with red fluid. Users are able to positively identify the targeted vessels and receive immediate feedback as to successful or unsuccessful vascular access. Re-filling venous and arterial fluid removed during central venous catheter procedures by using the provided QuickFill™ ports or and I.V. bag to continually refill the vessels during training.
