When Rabbit is coming down the hill to rescue the bikers that crashed just off the trail, the trauma bag in his hands changes position in his hands in between shots.
Rabbit is shown wearing his headphones and talking to the patient in a normal voice. This would not be possible due to the engine noise and the fact he was wearing headphones while the patient was not.
The rebar that Will gets impaled on supposedly goes between his external and internal iliac arteries. But these arteries are on the left side of the body, not the right, as shown.
