Arrow EZ-IO Intraosseous Vascular Access System:
A Line of Defense in Emergency Situations

In any situation where intravenous access is difficult or impossible to obtain in emergent, urgent, or medically necessary cases for up to 24 hours, the EZ-IO System provides peripheral venous access with central venous catheter performance.1-4

Can Your Patients Afford to Wait for IV Access?

16 minutes delay image
16 minutes

Average time needed for peripheral IV catheterization is reportedly as high as 16 minutes in patients with difficult vascular access11

forty percent image

40% failure

During emergency situations, vascular access fails up to 40% of the time12

It's time to think of intraosseous access earlier.
