Pulse Oximeter for Sleep Screening Operation Manual
Data Collection Mode
Data Collection Mode is intended for use in long-term collection of data in sleep screening
environments.
The Data Collection Mode will be entered when the verification timer reaches 10 minutes.
Once the trend data collection process has been started, trend memory will be filled
continuously until the end-of-memory is detected (approx. 12 hours) or the monitor is
powered down.
Invalid data (such as sensor off) is stored in trend memory, but is not used in the statistical
calculations.
The user functions in Data Collection Mode are:
The SpO
2
display will show one flashing bar and heart rate display will be blank (see Fig.
4.5).
Pressing and holding the
x
key for six (6) seconds will turn off the unit. While pressing the
x
key, the flashing bar will flash at a higher frequency indicating that the unit is about to
be powered down.
NOTE! If the
x
key is released before the six seconds elapses, the bar will return to its
normal flashing pattern.
After the power down, the unit will power up in the Trend Printing Mode.
NOTE! Once the monitor is powered off in the Data Collection Mode, it cannot resume
collection of trend data without clearing all previously obtained data.
Momentarily pressing the
F
key will reactivate the display for 30 seconds. Trend data will
not be affected.
Pressing and holding the
F
key will advance the paper (see pg. 7-5). Reloading the paper
is allowed in this mode.
The serial link to the PC computer will be suppressed in this mode.
