TyTek Medical’s 14 and 10 gauge TPAK chest decompression needles are the recommended 3.25" length for treating a tension pneumothorax. You can't count on a standard IV catheter to needle a chest deeply enough in needle thoracostomy. Our 14 and 10 gauge x 3.25" TPAK chest decompression needles are a compact, reliable solution for treating a tension pneumothorax. Their shock resistant case ensures the needle/catheters are secure upon deployment, and the capless flash chamber gives instant confirmation of needle placement in pre-hospital needle thoracostomy. Our TPAKs come in a rugged case, with a textured, easy-open hex cap.
