What to do if the ZOLL Medical Equipment displays 'CHECK CO2 ADAPTER'?
- AamandamccallAug 18, 2025
The error 'CHECK CO2 ADAPTER' on your ZOLL Medical Equipment typically occurs when the airway adapter is detached from the CAPNOSTAT 5 CO sensor, there's an optical obstruction on the adapter's windows, or an adapter zero wasn't performed after switching adapter types. You can resolve this by cleaning and reattaching the airway adapter. If the issue remains or the adapter type was changed, you should perform a mainstream airway adapter zero.
