Display PI (perfusion 
index)
(Masimo only)
Configures whether there will be a 
perfusion rate displayed in the digital tile. 
The perfusion index is a calculated 
percentage between the pulsatile signal 
and non-pulsatile signal of arterial blood 
moving through the site. PI is an 
indicator of the pulsatile strength. The 
perfusion index allows clinicians to 
assess the pulse strength at the 
monitoring site for optimal sensor 
placement.
On, Off
Sensitivity Mode
(Masimo only)
Choose the sensitivity mode depending 
upon signal quality and patient motion.
 
High
This mode should be used for the sickest 
patients, where obtaining a reading is 
most difficult. Maximum Sensitivity is
designed to interpret and display data 
for even the weakest of signals. This 
mode is recommended during 
procedures and when clinician and 
patient contact is continuous.
Normal
This mode provides the best
combination of sensitivity and probe off
detection performance. This mode
is recommended for the majority of
patients.
APOD (Adaptive Probe Off Detection)
This mode is the least sensitive in
picking up a reading on patients with
low perfusion but has the best detection
for probe-off conditions. This mode is
useful for patients that are at particular
risk of the sensor becoming detached
(pediatric, combative, etc.)
High, Normal, APOD 
Post Avg. Time
(Masimo only)
Configures the alarm delay.  2-4 sec, 4-6 sec, 8 sec, 10 sec, 12 sec, 
14 sec, 16 sec
Fast Sat
(Masimo only)
Configures whether there will be a 
turned on or off. FastSat enables rapid 
tracking of arterial oxygen saturation 
changes as may be required in urgent 
situations.
