Unable to Calibrate Fiber-Optic Sensor
Fiber-Optic Sensor Calibration Postponed
Probable Cause
Corrective Action
Patient’s pulse pressure is
inadequate for calibration.
When patient’s pulse pressure
improves, press CALIBRATE
PRESSURE key for 2 seconds
while IABP is assisting.
Provide alternate A.P. source
(i.e.: radial).
Extender tubing or
balloon catheter may be
restricted.
Relieve restriction.
Attempt calibration by press-
ing CALIBRATE PRESSURE
key for 2 seconds while IABP
is assisting.
Probable Cause
Corrective Action
A non-scheduled calibra-
tion update has been
intentionally postponed
because either patient’s
mean arterial pressure may
be too low to pause assist
or less than 15 minutes
have elapsed since last
calibration.
Assess patient to determine if
a brief pause in assist would
be tolerated, and if so, press
CALIBRATE PRESSURE key
for 2 seconds while IABP is
assisting.
Provide alternate A.P. source
(i.e.: radial).
Pump is in STANDBY.
Resume pumping, then press
CALIBRATE PRESSURE key
for 2 seconds to initiate
a calibration.
