TITLE
Difficulties In Visualising Blender Reading
DETAILS OF INCIDENT

Whilst using a mechanical gas blender the first gas on cardiopulmonary bypass showed a very low pCO2. Reducing gas flow rates made no difference. Swapping out the blender resolved the problem. On inspection the fine trim rotameter knob was found to be fully open delivering a gas flow in excess of 30L/min. When fully open the small ball float is difficult to visualise.

DETAILS OF INJURY TO PATIENT
TYPE OF DEVICE/MANUFACTURER
ACTION TAKEN

The Safety Committee recommends that a check is made on the gas blender to ensure that the rotameter knobs are correctly set prior to establishing CPB. Consider incorporating into departmental checklists if not already included.
