The sternum is not FDA approved and shouldn't be based on the length of the needle. The original sternal IO (not the FAST1) was the one that pierced the heart a few times and was off the market quick. It was basically the peds tibia IO kit repackaged.
The tibia is first choice, humorus second due to the amount of tissue over the upper arm. The tibia in the location of insertion typically has nothing but skin over it so muscular people or obese patients can always find/hit the tibia.
We've hooked them up to high pressure bags and they do flow well.
Bill, the marrow space is where you produce your blood cells and platelets and each space connects to the vascular system with great redundancy...thats how the fluids and drugs get to the heart really fast. The needles are 'screwed in', the peds ones are pushed and enter on a beveled needle which is why they leaked...these new ones have a concentric cutting edge and go in just under the size of the rest of the needle so no leak space once the needle is in past the tip.
