Treatment of obstructive shock
ALS assist and/or rapid transport
Patient assessment for late or deep cold injury (frostbite)
Affect skin appears to be white and waxy. In deep cold injury tissue death occurs. Days later the ski will turn dark black (dead) necrotic. (requires surgery) Do not Squeeze or poke the tissue. The condition of deeper tissues can be determined by gently feeling th area. Do the assessment as if the affected area was a broken bone.

List the steps to control bleeding
Apply firm pressure with the palm of your hand Hold the pressure firmly until the bleeding is controlled when apply direct pressure while resisting the temptation to apply layers of absorbent dressing. Once the bleeding is controlled, bandage a dressing firmly in place to form a pressure dressing. Do not remove dressing it has been placed on wound.

Examine the wound site. Remove object if you find perforation and you can see both ends of the object. Pull it out by the direction it entered the cheek, do not twist the object, if you find perforation but the tip of the object is also impaled into a deeper structure (palate) then stabilize the object and do not try to remove it. Position the patient to allow for drainage, unless spinal injury is indicated.
