Don’t repeatedly attempt intravenous access during a life-threatening event when intraosseous access is available.

In emergency situations, intravenous (IV) access can be difficult to obtain. Nurses often lose time trying to insert peripheral IVs, and insertion of central venous catheters may be initiated. However, intraosseous (IO) access is a faster and safer option, with less chance of complications, when inserted by trained personnel.
