“Obtaining emergent intraosseous (IO) access is an established procedure in critical care. Furthermore, in a large multicenter trial, IO was found to be quicker and more successful than peripheral intravenous (IV) or central venous access1. Traditional mechanisms for confirming successful IO placement remain historically static with rudimentary, best practice reliance on tactile feedback, catheter stability, and the ability to aspirate blood. Once an IO is established, clinicians are instructed to visually observe the insertion site for evidence of soft tissue swelling and the arbitrary flow of fluids. Unsuccessful, misplaced, or dislodged IO catheters can lead to clinically significant complications if unrecognized.”
