It is important to emphasize that ideal osmosis requires only the movement of pure water across the membrane without any […]
- Intraosseous Infusion ()
Introduction Intraosseous (IO) vascular access refers to the placement of a specialized hollow bore needle through the cortex of a bone into the medullary space for infusion of medical therapy and laboratory tests. The IO route is an option when standard venous access would delay therapy or is not easily obtained in the hospital or pre-hospital […]
