 WARNING 
z  If measuring intracranial pressure (ICP) with a sitting patient, level the transducer 
with the top of the patient’s ear. Incorrect leveling may give incorrect values. 
 
 
14.5 Understanding the IBP Display 
The IBP measurement is displayed on the monitor as a waveform and numeric pressures. The 
figure below shows the waveform and numerics for the Art pressure. For different pressures, 
this display may be slightly different. 
 
 
 
 
 
(1)  Waveform 
(2) Pressure unit  
(3) Systolic pressure 
(4) Diastolic pressure 
(5) Mean pressure  
 
For some pressures, the parameter window may show the mean pressure only. For different 
pressures, their defaults unit may be different. If the Art and ICP pressures are measured 
simultaneously, the ICP parameter area will display numeric CPP, which is obtained by 
subtracting ICP from the Art mean.
