Sistema Pulmodyne Control-Cric™ con Cric-Key™ y Cric-Knife™

What is the Pulmodyne Control-Cric system and how does it work?

The Pulmodyne Control-Cric™ System uses a proprietary Cric-Key™ device and Cric-Knife™ to perform cricothyrotomy using a technique different from the traditional open surgical approach. The Cric-Key combines the puncture, dilation, and tube introduction steps into a single integrated device, designed to reduce procedure complexity compared to the multiple separate steps of open surgical technique. The Cric-Knife is a specialized scalpel designed for the system's technique.

What does the NSN 6515-01-640-6701 mean?

NSN stands for National Stock Number — a standardized 13-digit identifier used by the U.S. Department of Defense to catalog items in the federal supply system. NSN 6515-01-640-6701 identifies the Pulmodyne Control-Cric System in the military logistics system, meaning it can be procured through government supply channels. The first four digits (6515) indicate the item class — in this case, medical instruments, equipment, and supplies. Having an NSN facilitates procurement by military medical units.

How does the Control-Cric compare to the bougie-aided open surgical technique?

A 2024 CoTCCC literature review found that evidence from multiple studies using trained providers did not show the Control-Cric outperforming the bougie-aided open surgical technique. In one mannequin study, the Control-Cric was ranked last in time to insertion. In a study using U.S. Army combat medics, it performed second or third out of three evaluated devices across all focus areas. The CoTCCC currently supports the bougie-aided open surgical approach as the recommended technique. Providers should consult their medical director for current authorized technique guidance.

Does the Control-Cric require specific training beyond standard surgical airway training?

Yes. Because the Control-Cric uses a proprietary technique with specialized instruments that differ from standard open surgical cricothyrotomy, providers need technique-specific training for this system — not just general surgical airway training. If a provider's medical director has not authorized the Control-Cric technique specifically, the provider should use an authorized kit aligned with their trained and authorized procedure. Never attempt any surgical airway technique without proper hands-on training and medical authorization.

Is there an NSN-stocked alternative for providers who want a CoTCCC-aligned surgical airway kit?

Yes. The NAR Tactical CricKit (10-0017) and NAR BAC-Pack (10-0052) are both engineered specifically to meet CoTCCC surgical airway kit requirements and are widely used across military and special operations medicine. These kits use the bougie-aided or standard open surgical technique that CoTCCC currently supports. The NAR Tracheostomy Kit with Bougie Introducer (10-0048) also has an NSN (6515-01-529-1187 associated with NAR products). Check with your unit supply chain for current NSN stocking.
