what does I.C.U. mean.
In the hospital it means "intensive care unit". I'm sure it can have other meanings.
You are correct! "ICU" commonly stands for "Intensive Care Unit" in a hospital setting. This is a specialized unit within a hospital that provides 24-hour care to critically ill patients who require constant monitoring and specialized medical treatment.
If you have come across "ICU" in another context, it's always a good idea to consider the specific field or industry in which it is being used. Acronyms can have multiple meanings depending on the context, so it's important to consider the relevant context when trying to understand the meaning.
