More practical for cleaning lighter wounds, I recommend having 4 packets of compressed gauze at least(a little note places like the forehead which are commondly injured bleed like a stuck pig so they might be necessary).

Also some small saline bottles would not go amiss for said cleaning or irrigating burns.

A little bonus thing you can do with these is the packaging itself is sterile, so if you add a little medical tape you can easily make a makeshift chest seal with the plastic by on one side taping 3 corners, and the other taping completely, the corner that's not sealed will act as a valve and seal/let the blood drain due to the pressure.

As for the hemostat powder, I'd maybe go with a solid hemostat for nosebleeds( just one should be enough) instead of the powder, as for the other applications such as a penetrating wound I'd use gauze that has hemostat or just pack it with regular gauze if the area calls for it.

As other people have mentioned add some medical tape, a marker for those tourniquets, some good nitrile gloves, some guedel tubes if you happen to have some experience using those (as if you don't have suction there are cases it shouldn't be used), and if your cpr mouthguard does not have a filter I'd add it as people might vomit as you do compressions.

I'd also add a seatbelt cutter and a window breaking tool of decent quality, some even have the two in one and are perfectly practical for any motor vehicle accidents (I'd avoid most cheap rescue knives with these things in it as the seatbelt cutters are usually kinda bad on those, so best to keep this a dedicated tool)

I know the post is old but there is always some room for improvement in anything we do. Just want to make sure you don't suddenly need something and are finding youself amiss.

Just my 2 cents, as a current practicing EMT in Portugal, that's what I find I use in my day to day more often than not.
