Clinical Situation Possible Cause Solution
90217 ABP Display is
incorrect
■ Data not retained ■ Replace backup battery
■ Low or no power ■ Check the batteries for a full charge; if
needed, replace or recharge the batteries
■ May be one of the following: time-out,
no reading due to air leak in the
system, improper cuff size, cuff size not
properly attached to the 90217 ABP
■ Isolate cause and correct
No NIBP alarms are
displayed
■ ECG “Leads Off” condition exists
■ Higher priority alarm condition is
present
■ Re-attach ECG lead wires to the patient
and resume ECG monitoring to clear
pending ECG alarms
■ Clear current alarm condition and/or
re-prioritize NIBP alarms of interest in the
Module Configuration Manager
■ When NIBP alarms are set ON, all NIBP
alarm conditions will cause the parameter
value (or ???) to blink according to the
alarm priority set by using the Module
Configuration Manager
Variable readings occur ■ Some arrhythmias may cause beat-to-
beat pressure and NIBP readings
■ Document arrhythmia if present, verify
pressure using another method, then
follow hospital procedure for care of this
type of patient
■ Larger than normal influence of
respiratory phases on blood pressure
(inspiratory fall in blood pressure;
expiratory rise)
■ NIBP software usually compensates for
normal variation
No NIBP readings or
questionable values in
the presence of shock
■ Peripheral vascular changes
experienced during shock may reduce
the reliability of blood pressure
readings obtained with any indirect
method; peripheral pulses may be
diminished or absent
■ Consider invasive pressure
measurements in patients with symptoms
of shock or in any patient who rapidly
becomes unstable for unknown reasons
90217 displays “LLL”
and alarm sounds
■ Low main battery condition ■ Turn off and replace batteries within 60
seconds after removal to continue
monitoring.
Cuff too tight ■ Cuff placed on patient too tightly ■ Reposition the cuff
■ Air pump staying on too long ■ Return unit to Spacelabs Medical for
service
Cuff too loose ■ Cuff placed on patient too loosely ■ Reposition the cuff
■ Air pump not staying on long enough ■ Return unit to Spacelabs Medical for
service
