What is the difference between emt and paramedic?

Let's break this down to the US version. There's are 3 levels of pre-hospital care in the US. The EMT system in the US is changing, it used to be: EMT-B(Basic), EMT-I(Intermediate) and EMT-P(Paramedic). This system is changing in most states to EMR, EMT, and EMT-P. The EMT is the mid level of pre-hospital care. This level usually requires about a year to a year and a half of college education and training. An EMT-I(EMT) can do some more advanced skills then the EMT-B(EMR) such as basic cardiac monitoring, cricothyrotomy and more medications. ALL levels of pre-hospital care are considered EMTs, but only the EMT-P is a Paramedic. The Paramedic is the most advanced level of EMT and requires about 2 years or college education and training. The Paramedic may do everything the EMT can do plus intubation, 12 lead ECG, administer 20 medications(depends on protocol) and more. Paramedics are Advanced Life Support(ALS) providers, the EMT-B is Basic Life Support(BLS) and the EMT-I is sort of a mix. Hopefully this helped answer your question. It's OK to call a Paramedic an EMT but you can't call a EMT a Paramedic.
