TQ's, have two be able to get to both of them with both hands. Be an expert in putting them on single handily with both hands. CAT or SOF-T/W are the best two by a long shot.
The QC sponges are nice in theory, but suck to use, they are nearly impossible to pack into a wound next to where the bleeding is. All hemostatics need to be placed directly on the sight of the bleeding to work. One of the hemostatic gauze products is the way to go.
The granular hemostatics have fallen far from favor for several reasons, from burns, difficult to place effectively, can wash out of the wound before becoming effective, at the same time can be difficult to remove, can cause embolism's. I would not advise buying any granular hemostatic at this point, go with hemostatic gauze! The gauze products are more effective and easier to use. But what you have on hand is better than the best ting in a store when it comes down to it.
On chest seals, they are nice to have and are effective. But the inside of a bandage wrapper will also work just fine to seal the chest. The wrapper method will not deplete your budget, add extra volume or weight to your kit and can be just as effective as a chest seal.
Chest decompression needle? Burping a chest defect (temporally opening the chest seal, then resealing) is an extremely effective technique to reduce a tension pneumothorax and provide temporary relief, until a licensed medical professional arrives to preform a chest decompression, or other procedure. This will also avoid the potential of being charged for practicing medicine without a license (decompressing a TPX is considered practicing medicine in all 50 states) It also prevents not preforming the procedure improperly, which can cause lethal side effects (most jurisdictions look at this as homicide). It also prevents decompressing a chest with a simple pneumothorax, hemothorax and or pulmonary contusion, all of which have the same basic signs and some of the same symptoms as a tension pneumothorax (TPX). A mistake doing a chest decompression can be a lethal mistake, this is a skill that requires a good deal of training to properly preform and a physician advisor who authorizes you to preform the procedure. It is also a some what rare procedure for a full time Paramedic in a busy urban system to preform, having supervised a very large urban EMS system in the past (quarterly training was required for all of my medics) this procedure was not always preformed properly. A TPX is a SLOW to develop condition, in most cases. Having preformed this procedure in training and also on living human patients in permissive and non-permissive situations many more times that I can count in the last 22 years it is a very serious procedure that should not be taken lightly. The military does allow this procedure to be preformed at a low level, but doing the same as the military would be a very poor choice CONUS for many legal reasons.
Also not everything that causes shortness of breath, confusion, loss of pulses in your wrist is a TPX. Only a TPX should be decompressed. Decompressing a chest without a TPX can cause serious to fatal harm to a person.
With that said, there is a growing body of evidence that will come out in the next 9-18 months on chest seals that will cause a radical paradigm shift. I was exposed to some of the data last week by a MD who is one of the authors of the TCCC text.
Protect your wounded from additional harm, then; stop the bleeding, keep them breathing, keep them warm, should be the priorities that you have for every causality.
Even if you work in medicine get more training in specifically in TCCC, even if you have been through ATLS, the changes that have come down based on what we have learned from wars balanced British, Canadian and USA studies in the last 5 years or so (heck even in the last two years) is massive, guidelines have changed and we are saving more lives with the changes than I have seen before in a very long career. The new guidelines are that good and effective!
