Acting on evidence-based medicine, North American Rescue is introducing the Enhanced ARS (Air Release System) as an additional offering in their needle decompression product line. The Enhanced ARS brings several features specifically implemented to address needs identified in the data.

The Enhanced ARS features an improved needle tip design with “scalpel” sharp, bi-bevel, tapered needle tip, which improves penetration control through tissue of varied type and thickness.

The new fenestrated catheter delivers statistically significant improvement for tension relief and the prevention of distal catheter occlusion when compared to traditional non-fenestrated catheters. The three fenestrations, combined with the catheter tip, deliver four paths for air to escape.

This exponentially decreases the potential for blockage that would interfere with airflow. During investigative research, fenestrated catheters were additionally shown to offer faster pressure relief and succeed when non-fenestrated catheters failed.

Centimeter graduated catheter for safer placement utilizing “thoracic depth control”. Evidence and anecdotal experiences continue to strongly suggest the need for insertion CONTROL with needle decompression.

Learning Point: Average depth from exterior of targeted RIB to parietal pleura is 0.5 - 1 cm. Centimeter markings allow for PRECISE placement just beyond the parietal pleura AND help clinicians PREVENT OVER INSERTION!

"The fenestrated catheters were almost two times more successful than the non-fenestrated catheters."

The flexible catheter is designed to decrease incidence of catheter kinking. Available in both a 14ga x 3.25-inch and 10ga x 3.25-inch (8.25cm) assembly to meet your protocols, the Enhanced ARS is protected in a rugged, rigid hard plastic case that features NAR’s Red Tip Technology® with textured cap for secure grip during opening. The case incorporates a pen clip to secure it during transport and includes color coded sterility seals that make it easy to identify gauge and sterility. Accordion-folded instructions for use are adhered to each needle case for reference. The Enhanced ARS is additionally supported with videos (depicting both anterior and lateral decompression) and PowerPoint slides.
