Used my Nitrile gloves and wound dressing from my EDC to provide first aid (together with other pedestrians) to an older man who has had a circulatory insufficiency and fell onto the street. He was injured on the head (laceration) with blood all over his head and jacket. While one lady ran to grab her car first aid kit (they are mandatory here) I was able to just pull out my sterile wound dressing from my EDC and, after applying Nitrile gloves, put this onto his head to cover the wound. Offering a second pair of Nitrile gloves to the lady that helped provide first aid was very well appreciated (also the car first aid kit contains those she simply forgot to put them on). As this happend in a town ambulance was on scence in a few minutes, who took over further treatment. Key take aways: I was amazed that we were four people in total taking care of the casualty: two providing first aid, one lady helped the gentlemen to lean back and not fall again on the street, one other lady to call 911 (well it's 112 here in Germany) - all of us where within a few yards when this happened, and anyone responded. Not sure if the spontaneous reaction would have been the same in a larger city ... according to statistics things are getting worser the larger the population in a place is; despite the fact that it's everyone's duty by law to provide first aid (at least call 911). Carrying a first aid kit with medical gloves (2 pairs) has proven itself to be helpful. Refilling took place as soon as I was back home. Self-protection (gloves, making sure traffic doesn't "hit", etc.) is important and can easily be forgotten - sometimes with very bad consequences for first responders. If things would have been worse, I would had have my trauma kit (includes a TQ as a last resort) close by. The ambulance took about 6 minutes to be on scene - that's fast, but still double the time one takes to bleed out with a larger wound. Of course there is always a dumb person close by ... in this case we had an middle-aged women who couldn't pass the accident as the street was partially blocked. The only thing she did was using her horn and screaming at us that we should move away as she needs to drive home. I asked her to please make a turn and use the street next to this one when she started arguing ... I left here alone, but noticed the car registration. Still considering if I should file a complaint with the local police. Summary: keep your first aid kit as part of your EDC, and a trauma kit (even if it's just a SWAT TQ + gauze) within reach - and don't forget to use the medical gloves.
