Prepare Intraosseous (Arms IO)
IO simulation with needle insertion is possible through the
humeral bone.
Ensure that the IO bone has not already been pierced or used.
To repair and replace the IO bone refer to Maintaining Arm IO
Bone.
Recommended Device Sizes
BIG Automatic Intraosseous Device 15 G
EZ-IO, 15 G x 1” 1.8 x 25 or 45 mm
Cautions
• Incorrect use of larger devices can damage the IO bone and/
or internal components. The smaller size is recommended.
• Do not inject fluids into the pads unless approved IO modules
with fluid outlets are in place.
