Indicator for ‘backscatter’ threshold.
‘
’ indicates that the backscatter return from the probe is
sufficient to allow reliable measurements.
‘
’ symbol indicates that the backscatter return from the
probe is below the cut-off threshold and may be
insufficient to allow reliable measurements.
‘
’ symbol indicates excessive backscatter.
Note: a persistent low backscatter (‘
’) state may be
alleviated by adjusting the cut-off threshold via the
dedicated settings toolbar function (see table 4 above).
Calibration data indicator.
‘
’ indicates that the probe has been calibrated.
‘
X
’ indicates that the probe requires calibration prior to
use (see section 3.6).

Probe Calibration
The OxyFlo Pro monitor is designed to automatically recognise and apply
the correct calibration coefficients when probes are connected.
Probes purchased with a monitor will be calibrated at the factory. Since the
calibration data is stored within the monitor, if a probe has previously been
calibrated for the channel it is being used in, then calibration coefficients will
be loaded automatically and the probe will be ready to use almost
immediately.
Where additional probes are purchased from Oxford Optronix Ltd.
subsequent to monitor delivery, a one-time user calibration is required in the
channel that the probe is to be used in.
IMPORTANT
:
For users wishing to use combined blood flow and oxygen/temperature
sensors (requiring the counter part OxyLite Pro oxygen/temperature
monitor), there is NO REQUIREMENT to carry out individual flow
calibration. These sensors will be recognized automatically by the OxyFlo
Pro with a ‘generic’ probe ID of 25.
When the calibration procedure ends, the calibration data for that particular
probe/channel configuration is automatically stored within the monitor. The
calibration data is then automatically retrieved every time that particular
probe is connected to that particular channel.
