Helo is OUT .... 12 min lift time, 21 flight time to my local, 10 min on scene time, plus another 21 min flight back = 64 min total time.

This is a load and go.
Do treatment in route.

Apply c-collar for c-spine precaution, but I would not board. If anything I'd use a scoop for any spinal immobilization, but seeing that the wounds are to the back, I would need to be able to get to them as needed.

Apply several occlusive dressings to those wounds in the upper thorax. Others would get trauma bandages to control bleeding.

Continue O2, possibly decreasing amount to 10L or enough to keep reservoir bag inflated.

Establish at least 2 IVs.
1st would be NS attached to blood pump 14 or 16 gauge angio. Bolus fluid as need to keep systolic BP above 90.
2nd IV, NS or possibly buff cap for med administration. No smaller than an 18 gauge (14, 16, 18)

If peripheral lines cannot be established, I would then establish IOs.

Be aware of Beck's Triad (low arterial blood pressure, distended neck veins, and distant, muffled heart sounds) due to possible cardiac tamponade. It would be difficult to see the neck veins due to the c-collar, but if the other two are present, I would consider removing the collar to observe the neck.

Be aware for possible pneumothorax, hemothorax or comination of both, hemopneumothorax.

As a basic, (soon to be Advanced) there's not much I can do to treat the above conditions, but I will have called ahead for possible ALS intercept. I would also consider if there are any hospitals along our route that at least were Level II, then at least we could get in there and let the MDs get the Pt. stable and then call in the Helo for air transport to Level I.

If no hospitals or ALS are available, then I would continue to monitor Pt. keeping systolic BP above 90 and O2 sats at or above 90 as well.

If Pt. has LOC, consider advanced airway (King tube or Combitube), keeping airway established. Apply AED pads, in case Pt. looses pulse, I'd have pads in place as needed.
