TROUBLESHOOTING
The DINAMAP
™
Portable Monitor Model 8100 has been
designed to provide safe and reliable operation in medical
environments. As with all medical devices, if the accuracy
of any determination value is questionable, first check the
patient's vital signs by alternate means and then check the
monitor.
Determination Unsuccessful Alarm (899)
This alarm is indicated by an alarm tone and a flashing 899
in the PULSE display. This alarm condition indicates that
the monitor is unable to make a determination. Possible
causes include: sudden changes in blood pressure;
excessive arrhythmias; cuff too loose; or arterial obstruction.
In auto mode, the monitor initiates two determinations at a
higher pump-up pressure followed by seven determinations
at the original pump-up pressure until a successful
determination in made. No more than nine retries will be
made if the 899 alarm condition persists. Move cuff to
another location and attempt another determination.
Power-On Alarm (888)
The power-ON alarm occurs anytime that power is
interrupted and then restored to the monitor, or after three
(3) minutes in cal mode. The alarm lasts for three seconds,
during which time the monitor displays all eights (888s) in
the digital displays; toggles all LED indicators on and off
and issues an audio tone.
After the alarm is issued, the monitor enters the manual
mode of operation with adult default alarm limits in effect.
Excess Time at One Pressure Alarm (855)
This alarm is indicated by an alarm tone and a flashing 855
in the PULSE display. The alarm is generated if the cuff
pressure is held at one pressure level for more than 60
seconds. Check the cuff and hose connections for kinks or
blockages and then initiate another determination.
