If you are an EMS student, you will guaranteed not be assisting in intubations as per hospital policies, regulations, and guidelines. If you were trying to say "observe" then that's something totally different. The most they will let you do is blood pressures and things of that nature. You would be the last person they ask to perform CPR on a coding patient; I mean they don't know who you are and you won't be there observing for long enough. Let us know which hospital let you do such things though. As an EMS student you have ZERO training to even by toying around with such things and honestly if you wanted that type of exposure, I would arrange that separately with the hospital when you are DONE with the EMS observatory requirements. They put you in the hospital for those 10-15 hours just so you know how the ER works.
If you think paramedicine is an "excellent" bridge, please let us know why instead of just saying you think so. Having gone to medical school with a former paramedic, the basic sciences portion, according to him, is not exactly similar to paramedic school.
