Refresh Rate
1s
Response Time
The maximum update period of saturation and pulse rate are 13s (% SpO2 value from 60 to
95% at 75 bpm) and 12s (bpm value from 60bpm to 100bpm).
SpO
2
Pitch Tone Adjustment
The systole beep is generated for each heart beat detection. The source for the trigger may
be from the ECG, IBP (Art, UAP, LV, PAP), or SpO
2
. The frequency of the tone is determined
by the SpO
2
value if it is present.
Low SpO
2
Alarm Limit
Exclusive alarm. Alarm limit range is between 76 and 99 and is correlated with SpO
2
alarm
low limit.
Alarm Suppression of Monitoring NIBP and SpO
2
Simultaneously
When NIBP and SpO
2
are monitored on the same limb simultaneously, users can choose this
function to suppress the false alarm during the period of venous block.
Alarm
SpO2 and PR alarms are optional.
DPM SpO
2
Module Accuracy
The DPM SpO
2
module accuracy has been validated in human studies against arterial blood
sample reference measured with a co-oximeter. Pulse oximeter measurements are statistically
distributed, and about two-thirds of the measurements can be expected to fall within the
specified accuaracy compared to the co-oximeter measurements.
Sensor Measurement Wavelengths
The sensor measurement wavelengths are nominally 660 nm for the red LED and 905 nm for
the infrared LED. Maximum optical power output for the LEDs is 18 mW. The maximum
photic output consumption of the sensor is less than 18 mW. This information may be useful
to clinicians, such as those performing photodynamic therapy.
