I didn't get much response to the "DIY petroleum gauze"... so I'd like to pose the question... what are others use for a penetrating chest wound where air is entering the pleural cavity?... multiple thoracic penetrations from shrapnel could be a serious problem... world class trauma centers were minutes away in Boston... probably not so close for most of us
A chest seal, such as the HALO. It's what I carry. I do have a decompression needle but I've been told very sternly that its beyond my scope of practice.
