Question: what is the difference between the emergency room and icu?
Answer: An intensive care unit (ICU) is different from an emergency room (ER). ... Sicker people will be going to an ICU. The ICU is like an extension of the ER. ER doctors do all of the stabilizing measures, make sure that people are all wrapped up, and then they will be sent to the ICU, where they can be taken care of long term.
