2.1.3 MaxBlend 2+p Setup
1. Connect the pressurized air source to the Air Inlet Connector.
2. Connect the pressurized oxygen source to the O2 Inlet Fitting.
3. Flush gas at the highest possible flow rate through the blender for at least one minute
to eliminate any particulate that may have been introduced into the system during
handling and installation.
2.1.4 Sensor Installation
1. Attach the flow diverter onto the oxygen sensor.
2. Place the sensor into the sensor port located behind the flowmeter.

3. Attach the sensor cable directly to the sensor and the sensor jack on the back of the
monitor enclosure. Ensure the cable is fully inserted into both connections.
4. Calibrate the sensor prior to use according to the calibration procedures in section 2.8
2.2 Monitoring
Before use on a patient, the oxygen concentration of the delivered gas should be checked at
the setting intended for use.
1. To begin monitoring, press the ON/OFF key
will begin immediately.
2. Should oxygen level exceed either the HIGH or LOW alarm set points, the alarm indicator
on the front panel will illuminate indicating either a high or low oxygen condition. The
alarm will cease when oxygen levels are within limits, or the limits are adjusted.
NOTE: The MaxBlend 2+p will monitor the oxygen concentration of the gas delivered from
the blender regardless of which outlet port is in use. Therefore, the integrated flowmeter has
ultimately no effect on the oxygen sensing.
2.3 Alarm Setting Procedure
2.3.1 Low Alarm Setting
To adjust the low alarm setting:
1. Press the Unlock key
HIGH icons will begin to flash indicating the SET OPERATING MODE.
2. Press the DOWN (Low Alarm) key
Select oxygen or pressure by pressing the power/mode key
NOTE: The Low Alarm digits begin to flash indicating the Low Alarm manual setting.
3. Use the UP
Pressing the arrow keys changes the value in 1% or 1 cmH
held down for more than 1 second the display will scroll at a rate of 1% or 1 cmH
second.
NOTE: If 30 seconds elapse between key actuations, the system will store the latest low alarm
setting and will revert to normal operation. If this occurs inadvertently, simply repeat the

alarm setting procedure.

or
There is a special condition that allows the low oxygen alarm to be set below 18%. To access
this condition, press the DOWN arrow key for three seconds while the low alarm reading dis-
plays 18%. The alarm setting can now be adjusted to 17, 16, or 15%. A bar will blink above the
setting to provide further indication that the alarm has been set to this special <18% condition.
The low alarm value cannot be set lower than 15%, nor can it be set closer than 1% from the
high alarm value. For example, if the high alarm is set at 25%, the system will not accept a low
alarm setting greater than 24%.
When the low alarm value is set, press the Unlock key again to accept the low alarm setting
and return to normal operation.
NOTE: The default low alarm setting is 18% O2 and off (––) for pressure. Removing the batter-
ies or shutting the unit OFF will reset the low alarm limit to 18% if it is set to <18%.
2.3.2 High Alarm Setting
To adjust the high alarm setting:
1. Press the Unlock key to unlock the keypad. Note the LOW, SMART ALARM, CAL and HIGH
icons will begin to flash indicating the SET OPERATING MODE.
Select oxygen or pressure by pressing the power/mode key
2. Press the UP (High Alarm) key on the keypad.
NOTE: The High Alarm digits begin to flash indicating the High Alarm manual setting.
