Averaging
5 - 20 seconds (default = 10 seconds)
The effect of SpO
2
pulse oximetry on data averaging is internally controllable
by the patient worn monitorMX40, with no user controls.
SpO

& Pulse Numerics -
Update Rate
Transmitted once per second.
Note—The update rate for the SpO
2
pulse oximetry value and pulse rate is
typically 1 second. This can be extended to a max. 60 s when NBP is
measured on the same limb, with a corresponding INOP message after a
max. of 30 s, indicating that the displayed values are not current values.
Pleth Wave- Sampling
Rate
125 sps
Technical Alarms
(INOPs)
Triggered if the sensor is disconnected, if a pulse is not detected, if the signal
is noisy, if light interference is detected, if the sensor is defective, if the
measurement is erratic, or if the module is malfunctioning
Wavelength Range 500 to 1000 nm
Note—Information about wavelength range can be especially useful to
clinicians (e.g., clinicians performing photodynamic therapy).
