The new Needle Decompression kit is the result of a two year collaboration with Pre-hospital providers and data obtained from ongoing combat operations. Our patented design increases the likelihood of success in the management of casualties who present with signs and symptoms of a tension pneumothorax. An easy opening needle system has been removed to allow for immediate confirmation of placement. Through the use of Analytical Thinking, Evidence- Based Medicine, inherent survival stress behaviours were identified and fail-safe characteristics implemented into the product design.
