AK 98 TROUBLESHOOTING
Changing a Wet Transducer

2. Reduce blood flow.
3. Clamp transducer line.
4. Remove wet transducer protector from connector on machine and
inspect for blood or priming solution strike-through.

Note: Do NOT inject air beyond the T junction on the transducer line.
Note: If changing the venous transducer protector, slowly inject
2 mL of air into the line to the venous chamber.
8. Attach new transducer protector to pressure transducer line. Ensure
secure connection between transducer protector and line.
9. Attach transducer protector to AK 98, ensuring a secure connection
between transducer protector and machine.
