Equipment messages for the Sidestream CO
2
option can appear on the display in an
equipment alert window.
ALTIMETER FAILURE - RANGE . The Propaq is operating at an altitude outside the
Sidestream CO
2
option’s operating altitude range of -2,000 to 15,000 feet. Returning the
monitor to within this range automatically cancels this message and restores operation.
ALTIMETER FAILURE - RATE . The altimeter has detected that the ambient pressure is
changing at a rate greater than 100 mmHg/minute. When the rate of change is back
within the 100 mmHg/minute range, disconnect and reconnect the CO
2
sensor to the
Propaq.
ALTIMETER NOT CALIBRATED - EEPROM - The Sidestream CO
2
option has not been
calibrated. Refer the Propaq to a Biomedical Engineer for calibration.
AMBIENT TEMPERATURE TOO HIGH . The sensor temperature is too high. The
Sidestream CO
2
option is disabled until the ambient temperature is within the operating
range specifications.
AMBIENT TEMPERATURE TOO LOW . The sensor temperature is too low. The
Sidestream CO
2
option is disabled until the ambient temperature is within the operating
range specifications.
CALIBRATION ERROR, SERVICE REQUIRED. Send the Propaq to a Biomedical
Engineer for service.
DEGRADED WAVEFORM, SERVICE REQUIRED . Send the Propaq to a Biomedical
Engineer for service.
LACK OF WAVEFORM, SERVICE REQUIRED . Send the Propaq to a Biomedical
Engineer for service.
MOTOR FAILURE, SERVICE REQUIRED. The sensor hardware has failed. Send the
Propaq to a Biomedical Engineer for service.
NO WATERTRAP DETECTED . There is no Sidestream CO
2
watertrap installed. Install
a watertrap.
OCCLUSION - CHECK EXHAUST PORT/TUBING . Blockage has been detected on the
pneumatic exhaust port. Check the exhaust port and related tubing for occlusions. Make
sure that the sampling line and any inputs to the patient breathing apparatus are not
