Pulse Amplitude Index for the WW1020 Oximeter
Range: 0.03% to 20.00%
6
(0.01% increments)
Pulse Amplitude Index is defined as PI = (100 * AC)/DC where AC is
the alternating current (pulsatile component of the signal) and DC is
direct current (non-pulsatile component of the signal). It is a relative
measure of pulse-signal strength over time at a pulse oximeter
monitoring site, and is non-pulsatile in nature.
Display: 9-segment green / yellow LED bargraph, logarithmic scale
Display Update Rate: 10 Hz
The oximeter will display dashes (Invalid data) for SpO
2
and PR when the PI value is below 0.03%.
Low perfusion performance is verified by simulator testing.

As tested with Industry Standard Simulator.
The PI value maps to a 9-segment bar graph as shown below. The two lowest bars (1&2) are bi-
color (Yellow & Green), and bars 3 through 9 are Green.

(0.2% increments)
Pulse Amplitude Index is defined as PI = (100 * AC)/DC where AC
is the alternating current (pulsatile component of the signal) and
DC is direct current (non-pulsatile component of the signal). It is
a relative measure of pulse-signal strength over time at a pulse
oximeter monitoring site, and is non-pulsatile in nature.
