Hey, I'm training to be an EMT-Basic and I'm still having some trouble in determining when to assist the patients ventilations and when to just do a nonrebreather mask. I am a little confused because I have been taught that if their breathing rate is under 8 or over 28, that their ventilations should be assisted. Is this still true if they are semi-concious? Is it okay to ventilate a patient who is not unconcious? Is it okay to insert a nasopharyngeal airway is someone who is not unconcious? Can anyone help me out with basic determining factors on whether to give nonrebreather or assisted vents? I have idea but I'm hoping people can give me reinforcement so I have a better idea of how to make my decisions.
