@medical8220: Intraosseous (IO) access is a rapid, life-saving technique to get fluids, blood, and medications into the body when standard IV access fails, by drilling a needle through the outer bone into the marrow cavity, a non-collapsible source connected to the central venous system, useful in emergencies like shock or cardiac arrest. The proximal tibia is a common site, and delivery rates are similar to IVs, with IO access generally limited to 24 hours to prevent complications.
