Pressure Monitoring And Alarms; Basic Operation; Pressure Monitoring Operation; Disabling Oxygen Monitoring - Maxtec MaxO2 ME+p Instructions For Use Manual

3.1.3 Smart Alarm Mode
NOTE: Smart alarms function as alarm guardrails which simultaneously set the low and high
alarms to ± 3% oxgyen or ± 2 cmH O of the current oxygen or pressure reading. This range can

be broadened by pressing the up button or narrowed by pressing the down button.
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 Smart Alarm key on the keypad. Note the LOW digits, Alarm Mode and
HIGH digits begin a slow flash indicating SMART ALARM MODE. The high alarm will now be
set to be equal to the current reading +3% or + 2 cmH₂0 (rounded to the nearest integer).
The low alarm will now be set to be equal to the current reading -3% or - 2 cmH₂0
(rounded to the nearest integer but never lower than 18%).
3. Pressing the Up key will add one to the high alarm setting and subtract one from
the low alarm setting. Pressing the Down
alarm setting and add one to the low alarm setting. In other words, the Up Arrow
widens the alarm band and the down arrow tightens the alarm band. This feature will
not set the alarm levels above 100% or below 18% for oxygen or above 60 cmH
below 1 cmH O for pressure.

4. Once the desired alarm settings are attained, press the Unlock
settings and return to normal operation mode. If 30 seconds elapse without a key
press by the user, the device will automatically save the new alarm settings and return
to normal operation mode.
3.1.4 Pressure Monitoring and Alarms
The monitor displays the mean pressure using a 2 second average. Pressure monitoring
begins immediately once the device is powered on. The device will activate an audible and
visual (LED) alarm whenever the alarm limits are exceeded, however the pressure alarms are
delayed by 3 seconds to allow for momentary fluctuations in pressure and reduce unnecessary
alarm disturbances.
By default, the pressure alarms are set to off (--) for the LOW alarm and and 15 cmH
HIGH alarm. Pressure alarms are automatically saved in the device memory and recalled to the
last settings whenever the device is powered on/off. Alarm default setpoints are only reset by
removing and re-installing the batteries.
3.2 Basic Operation
To check the oxygen concentration of a sample gas:
1. Using the ON/OFF key , make sure the unit is in the power on mode and properly
calibrated.
2. Place the external flow diverter in the sample gas stream. When using a standard
"T" adapter, make sure the sensor is mounted in the adapter with the flow diverter
pointing downward. This will prevent moisture from potentially draining into the
sensor membrane.
NOTE: It is important that a tight fit exists between the diverter and the "T" adapter.
3. Initiate flow of the sample gas to the sensor.
3.2.1 Pressure Monitoring Operation
The monitor measures pressure using pressure monitoring line with moisture control tubing
that includes and inline filter. The filter protects the monitor from moisture and reduces the
risk of cross contamination. The pressure monitoring line and filter is single use and should
always be discarded between patients. When in use on a single patient in an ongoing proce-
dure, it must be discarded and replaced every 30 days or sooner
To begin pressure monitoring:
1. Perform a zero calibration if the monitor displays a non-zero pressure reading. (See
section 2.3.5)
2. Locate the pressure monitor port on the device and push in the connector of pressure
monitoring line until it clicks into place.

3. Locate and attach the other end of the pressure monitoring line into the circuit to be
monitored using the Luer connector.
4. Adjust the low and high pressure alarms to the desired range. Alternatively, the
pressure alarms may be set automatically using the smart alarm button.
5. The device will now monitor pressure between the set range.
WARNING: In order to reduce the potential issues associated with condensation in the
pressure monitoring line, the pressure monitoring line connector should be positioned at least
10 inches (25 cm) below the monitor.
WARNING: To reduce the risk of cross contamination, only single use pressure monitoring
line with an inline filter should be used with this device.

to cause cancer and/or reproductive harm. For more information, go to www.p65warnings.

DO NOT allow liquids or debris to enter the pressure monitor port.
Replace the pressure monitoring line if condensation build-up occurs.
◆
DO NOT use for pressure in excess of 60 cmH
DO NOT connect pressure monitoring line to patient IV line.
The pressure monitoring line is intended to be used on an individual patient during a single
◆
procedure then disposed of. The pressure monitoring line must be discarded and replaced
between each patient and procedure. When in use on a single patient in an ongoing proce-
dure, it must be discarded and replaced every 30 days or sooner. The pressure monitoring
line is NOT intended to be reprocessed.
3.2.2 Disabling Oxygen Monitoring
The MaxO2 ME+p may be used to monitor pressure only by disabling the oxygen monitor.
The oxygen monitoring function may be disabled by disconnecting the oxygen sensor and
cable. The MaxO2 ME+p will display an E02 error indicating a sensor disconnect. Acknowledge
the error by pressing the alarm silence
read - - -, indicating the oxygen sensor has been removed and no oxygen reading is available.
In this configuration, the MaxO2 ME+p will only monitor pressure in the upper portion of the
display with the associated low
may be restored by reattaching the oxygen sensor and cable, which will trigger an automatic
calibration of the oxygen sensor.
NOTE: The oxygen sensor disconnect error (E02) will repeat anytime the device is turned off
with the oxygen sensor disconnected.
WARNING: Disconnecting the oxygen sensor will disable all oxygen monitoring functions
and alarms.
