Try to reinitiatepumping by powering down andback up.UNABLE TO ZERO APAlarm and message erase when APZERO/CAL button is releasedAttempts to ZERO with APsignal present.Check stopcock and line setup.ZERO/CAL with stopcock turned offto the patient.CONSTANT ALARM TONE(NO MESSAGE)No message, deflate balloon; stopspumpingProlonged balloon inflation.Call for service. Try to reinitiatepumping by powering down andback up.BALLOON PRESSURE WAVEFORMS:USE IN TROUBLESHOOTING ALARM CONDITIONSThe BPW is obtained from a built-in pressure transducer attached to the patient side of the isolator assembly.Alarm conditions are detected by a change of pressure in the closed system on the patients side.
Normal Balloon Pressure Waveform:A. Balloon pressure baselineB. Rapid inflationC. Pressure overshoot (peak inflation artifact)D. Balloon plateauE. Plateau endpointF. DeflationG. Zero-undershoot (peak deflation artifact)Normal Variations:BRADYCARDIA TACHYCARDIA HYPOTENSION HYPERTENSION
