So here's a question:
Say I get out on a call similar to the ones I was asking about. (a real call, not something I have to get through in order to get out of this class) Let's assume the patient cut of 3 fingers with a circular saw. (no c-spine trauma) He is in horrible pain and he knows his career as a concert pianist is ruined. He is tachycardic, and tachypneic, which is not surprising. He is pale, cool, and diaphoretic, and admits to fainting at the sight of blood, of which there is plenty.
So he might faint, but he hasn't yet. He has lost some blood, but not enough to think he could go into shock with from blood loss alone. We are about 30 minutes from a hospital. My partner wants to put him on Oxygen because that is what we learned in class.
Are the odds more in favor of:
a. He does not need O2, and if I give it, it will cause harm
b. He might need O2, and if I withhold it, it will cause harm
c. He does not need O2, but if I give it, nothing will happen
