This equipment is intended for use in the presence of electrosurgery; however, its general operation might be affected by the use of an electrosurgical unit (ESU).
As with all medical equipment, carefully route patient cables and connections to reduce
the possibility of patient entanglement or strangulation.
Use the Avant 2120 only within the specified temperature ranges: +32°F to +122°F
(0°C to 50°C) for operating, and -22°F to 122°F (-30°C to +50°C) for storage and
transportation.
Do not use a damaged sensor or NIBP cuff under any circumstances.
All parts and accessories connected to the serial port of the Avant 2120 must be certified according to IEC Standard EN 60950 or UL 1950 for data-processing equipment.
Use the Avant 2120 with 300PS-XX, where XX represents the power supply designation.
The Avant 2120 NIBP function has been designed for use on patients with normal sinus
rhythms.
Use only NONIN-manufactured pulse oximeter sensors. These sensors are manufactured to meet the accuracy specifications for NONIN pulse oximeters. Using other
manufacturers’ sensors can result in improper pulse oximeter performance.
Discontinue use of adhesive tape strips if the patient exhibits an allergic reaction to the
adhesive material.
Explosion Hazard: Do not use the Avant 2120 in an explosive atmosphere or in the
presence of flammable anesthetics or gases.
Do not stretch the adhesive tape while applying the pulse oximeter sensor.
Applying the blood pressure cuff to the same arm used for a pulse oximeter might affect

Ensure that all Avant 2120 users know how to manually remove the blood pressure cuff
in case it fails to deflate.
The safety and effectiveness of the Avant 2120 NIBP function in pregnant women have
not been established.
Do not operate the Avant 2120 blood pressure module unless it has been properly calibrated. Inaccurate blood pressure readings can result if the Avant 2120 has not been
calibrated properly. A calibration check is recommended at least once every year.
Cautions
Before using any sensor or NIBP cuff, carefully read the Directions for Use, which contain specific application times.
Do not, under any circumstances, perform any testing or maintenance on the Avant
2120 while it is being used to monitor a patient.
This equipment complies with International Standard EN 60601-1-2:1993 for electromagnetic compatibility for medical electrical equipment and/or systems. This standard
is designed to provide reasonable protection against harmful interference in a typical
medical installation. However, because of the proliferation of radio-frequency transmitting equipment and other sources of electrical noise in healthcare and other environments (for example, cellular phones, mobile two-way radios, electrical appliances), it is
possible that high levels of such interference due to close proximity or strength of a
source might disrupt the performance of this device.
Verify that all visible indicators light during the start- up (initialization) sequence. If any
indicator does not illuminate (except the AC Power Adapter LED), do not use the
Avant 2120. Contact NONIN Customer Support for assistance.
If the Avant 2120 fails to respond as described, discontinue use until the situation has
been corrected by qualified personnel.
Do not remove any covers other than the battery cover when replacing batteries. There
are no user-serviceable parts inside—other than the replaceable batteries.
Batteries might leak or explode if used or disposed of improperly.
Follow local governing ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries.
Do not immerse the Avant 2120 or NONIN sensors in water or any other liquids, and
do not place liquids on top of the Avant 2120.
The Avant 2120 is a precision electronic instrument. It must be repaired by trained
NONIN personnel only.
The Avant 2120 is designed to determine the percentage of arterial oxygen saturation of
functional hemoglobin. Significant levels of dysfunctional hemoglobin, such as methemoglobin, might affect the accuracy of the measurement.
The Avant 2120 might misinterpret motion as good pulse quality (as indicated by a
green pulse quality display). Minimize the patient’s finger motion as much as possible,
or change the type of sensor being used (e.g., ear clip).
3
Page 7
Precautions for Use
Check the pulse oximeter sensor application site frequently to determine the positioning
of the sensor and the circulation and skin sensitivity of the patient. Patient sensitivity to
the Avant 2120 varies depending on medical status or skin condition.
Do not use the 300PS-UNIV battery charger if the integrity of the protective earth conductor of the AC cord or the outlet is in doubt.
Cardiogreen and other intravascular dyes, depending upon their concentrations, might
affect the accuracy of the SpO
Ear Clip and Reflectance sensors are not recommended for pediatric use. The accuracy
of the sensors has not been established for pediatric use.
Some nail polish colors or artificial nails can reduce light transmission and affect SpO2
accuracy.
Check the NIBP cuff application site frequently to ensure that the cuff is not causing
prolonged impairment of the patient’s circulation.
The Avant 2120 might not work on all patients. Check to ensure that the proper cuff
size is used. If you are unable to achieve stable readings, discontinue use.
In certain circumstances, the normal application of a blood pressure cuff might exasperate an underlying medical condition. Be aware of potential circulatory disorders in all
patients using the Avant 2120.
Blood pressure recordings can be affected by the subject’s position, physiological condition, and other factors.

Taking Blood Pressure Measurements
This section describes how to take blood pressure readings with the Avant 2120.
NOTE: If an accurate NIBP reading cannot be achieved, the Avant 2120’s
cuff will begin to reinflate, attempting a second blood pressure
measurement. If the cuff does not automatically reinflate, restart
the blood pressure reading, and/or adjust the cuff position as
necessary. The device will time out two minutes after a reading
cannot be determined.
Inaccurate NIBP measurements can result from many sources, but users can take
precautions to ensure that the Avant 2120 operates efficiently. Blood pressure
readings might be compromised if patient motion is excessive, if an inappropriate
cuff size is being used, if the cuff is positioned improperly, or if the patient has a
restricted blood flow.
If inaccurate blood pressure measurements are suspected, ensure that the arm cuff
is positioned properly and that the Avant 2120 has been properly calibrated.
NIBP Cuff Selection
In order to guarantee accurate readings, the appropriate cuff size must be selected
for each patient.
CAUTION! Use only Nonin-supplied blood pressure cuffs and hoses
with the Avant 2120. Using other cuffs might result in
inaccurate readings or inability to operate the Avant 2120.
Small Adult BP Cuff 18-26 cm arm circumference
Standard Adult BP Cuff 26-35 cm arm circumference
Large Adult BP Cuff 32-42 cm arm circumference

Page 17
Using the Avant 2120
NIBP Cuff Placement
Cuffs can be carefully placed on either the right or left arm. Apply the cuff around
the bicep slightly above the elbow, so that the inflation bladder is centered over the
brachial artery (the inflation bladder is approximately half of the entire length of the
cuff). Do not apply the blood pressure cuff to an arm encumbered with an IV. The
patient’s arm should be resting comfortably, preferably at a level that is parallel to his
or her heart, with the arm adjusted so that the palm is positioned upward.
If a comfortable fit is difficult to achieve, a different cuff size might be required.
Refer to the circumference size in centimeters, which is printed on the cuff label.
Blood pressure arm cuffs should be applied directly to the patient’s skin. Applying cuffs over shirt
sleeves or other materials could affect the accuracy of blood pressure readings.
Patients should maintain a relaxed position with feet flat on the floor (if sitting).
Opposite limbs should be used for the blood pressure arm cuff and the finger clip
sensor.
WARNING! In order to achieve accurate results—and for important
safety reasons—the blood pressure cuff must only be placed
on the patient’s arm.

Use the following procedure to take blood pressure measurements with the Avant
2120.
NOTE: The NIBP unit can be used without the oximeter. If the unit is
turned on without an oximeter sensor, the oximeter will be
disabled and the SpO
display will remain blank. Plugging in the

3. Carefully place the blood pressure arm cuff around the patient’s bicep.
NOTE: Blood pressure cuffs can be placed on either the right or left
arm, but accurate readings depend upon using opposite limbs
for the finger clip sensor and blood pressure cuff.
4. Place the finger clip sensor on the patient’s finger. While the sensor is in
place, do not press it against any surface and do not squeeze or hold it
together. The correct amount of pressure will automatically be applied.
Additional pressure might cause incorrect readings.
5. When the patient is ready, press the NIBP button to begin a single blood
pressure measurement. The arm cuff will begin inflating, and the cuff
pressure value will appear in the Time LED area on the front panel display.
6. Wait for the reading to be completed. When the reading is complete, the
Systolic, Diastolic, and MAP numeric LEDs will illuminate—providing the
results for blood pressure. If there is no pulse rate value measured from the
oximeter sensor, the pulse rate value from the NIBP will illuminate.
NOTE: If the finger clip sensor is not worn while blood pressure is
measured, the Avant 2120 will display heart rate information
as measured from the blood pressure arm cuff; however, no
data will be displayed. When the finger clip sensor is
%SpO
2
worn, the %SpO2 and heart rate data are displayed based
upon readings only from the finger clip sensor—not the blood
pressure reading.
NOTE: If a blood pressure reading must be cancelled for any reason,
simply press any button on the front panel—except the Alarm
Silence button—to stop the reading and deflate the cuff.
Pressing the Alarm Silence button will not cancel blood
pressure readings.
Automatic and Demand NIBP Measurements
The Auto NIBP Cycle Time button is used to begin or end timed blood pressure
measurements and display the Auto NIBP Cycle time, which can be adjusted using
the Plus (+) and Minus (-) buttons. Blood pressure readings can be started every
1, 2, 3, 5, 10, 15, 30, 45, 60, or 90 minutes after the previous reading. The NIBP timer
begins after the previous blood pressure measurement is completed.
Automatic NIBP measurements are useful in many circumstances. They are
especially appropriate when continuous spot-checking of patients is desired or to
determine fluctuations in blood pressure over periods of time.
Demand NIBP measurements are single-time measurements taken by pressing the
NIBP button on the Avant 2120. They are useful for individual readings and when
long-term spot-checking is unnecessary.

Using the Avant 2120
Printing Quick Reference
Your Avant 2120 features new printing capabilities, allowing you to print on
demand or in real-time. These printing capabilities are controlled by DIP switch
4, which is found under the battery cover at the back of the unit.
• When DIP switch 4 is in the UP position, real-time (once per second) data output
is available via the RS232 connector port, using a null modem cable.
• When DIP switch 4 is in the DOWN position (default), the Print-on-Demand
mode is activated, allowing you to print only when desired.
There are three ways to print when the Avant 2120 is in Print-on-Demand mode:
Print-On-Demand Press Printout
Normal Mode
Prints displayed data.
History Mode
Auto NIBP Mode
Prints displayed history data.
Prints displayed data and will automatically print all new displayed data
upon completion of NIBP reading.
Important Notes
• Event markers are not available in Print-On-Demand mode.
• Data must be allowed to finish printing before entering History Review
mode.
• When there is invalid NIBP data, “BP=Error” will print in place of
“SYS=XXX DIA=XXX MAP=XXX” for all Print-On-Demand formats.
• Valid SpO

Care and Maintenance
The advanced digital circuitry within the pulse oximeter of the Avant 2120 requires
no calibration or periodic maintenance other than battery replacement. The NIBP
module requires calibration after every 10,000 inflations or once each year.
Field repair of the Avant 2120 circuitry is not possible. Do not attempt to open the
Avant 2120 case or repair the electronics. Opening the case will damage the Avant
2120 and void the warranty. If the Avant 2120 is not functioning properly, see
“Troubleshooting.”
Cleaning the Avant 2120
Clean the Avant 2120 separately from its associated sensors. For instructions
regarding cleaning pulse oximeter sensors, refer to the appropriate pulse oximeter
sensor package inserts.
Clean the Avant 2120 with a soft cloth dampened with isopropyl alcohol. Do not
pour or spray any liquids onto the Avant 2120, and do not allow any liquid to enter
any openings in the device. Allow the Avant 2120 to dry thoroughly before reuse.
Cleaning the Blood Pressure Arm Cuff
To clean the blood pressure arm cuff, simply wipe the cuff with a soft cloth
dampened with isopropyl alcohol. Do not pour or spray any liquids onto the arm
cuff, and allow the cuff to dry thoroughly before reusing it.

Alarms and Limits
Alarms and Limits
This chapter describes the alarms, limits, and error codes for the Avant 2120.
Alarms
The Avant 2120 provides a variety of audible and visual alarms, which are either high
or medium priority. It also provides informational tones.
High Priority Alarms
High priority alarms are those that require immediate attention to the patient. On
the Avant 2120, high priority alarms are indicated with rapidly blinking red LED
displays when alarm limits are met or exceeded. In addition, the pulse strength
bargraph LED may illuminate a red segment to indicate low perfusion.
High priority alarms are sounded as follows: “beep, beep, beep,” (short pause),
“beep, beep” (10-second pause).
Medium Priority Alarms
Medium priority alarms are those that signal potential problems with the equipment
or other non-life-threatening situations. On the Avant 2120, medium priority alarms
are indicated with slowly blinking amber displays.
Medium priority alarms are illuminated amber on the Main Alarm LED and on the
appropriate indicator(s) or numeric displays, sometimes displaying an error code to
help the user identify the source of the error. Use the “Error Codes” table to
identify error codes that might appear on the Avant 2120 front panel. All error codes
are displayed in the MAP display area.
Medium priority alarms are sounded as follows: “beep, beep, beep,” (25-second
pause), “beep, beep, beep.”
Watchdog Alarm
Watchdog alarms are loud, two-tone, steadily beeping signals that indicate a
hardware or software malfunction. When a watchdog alarm is activated, it can be
cleared by shutting down the Avant 2120 (press and hold the ON/STANDBY
button for one second). If the watchdog alarm cannot be cleared, contact NONIN
Customer Support.
Informational Tones
Informational tones communicate important information. They are typically single
“beeps” or a series of three “beeps.” Informational tones include the startup/
initialization tone and the pulse rate tone (which changes in pitch with SpO
values).

Memory Features
The Avant 2120 can collect and store up to 33.5 hours of SpO2 and pulse rate
information.
Data may be played back with data retrieval software (NONIN’s nVISION™
software is recommended). If you wish to create your own software, contact
NONIN for the data format.
NOTE: Only SpO
The memory in the Avant 2120 functions much like an “endless loop” tape. When
the memory fills up, the unit begins overwriting the oldest data with the new data.
Each time the Avant 2120 is turned on, the current time/date information (if the
clock is set properly) is stored in memory, starting a new recording session. Only
recording sessions greater than one minute in length are stored in memory.
Patient SpO
extreme value of the 4-second sample period is stored. Oxygen saturation values are
stored in 1% increments in the range of 0 to 100%.
The stored pulse rate ranges from 18 to 300 pulses per minute. The stored values
are in increments of one pulse per minute in the interval from 18 to 200 pulses per
minute, and in increments of 2 pulses per minute in the interval from 201 to 300
pulses per minute.

Real-Time Patient Data Output
The Avant 2120 provides real-time data output capability via the RS232 connector
port. A null modem cable must be connected from the Avant 2120 to the receiving
computer.
RS232
Connector
Port
The information from the Avant 2120 in the real-time mode is sent in an ASCII
serial format at 9600 baud with 9 data bits, 1 start bit, and 1 stop bit. The data are
output at a rate of once per second (on separate lines).
Real-time data may be printed or displayed by devices other than the pulse oximeter.
Upon power up, a header is sent identifying the format and the time and date.
Thereafter, the data are sent once per second by the Avant 2120 in the following
format:
SPO2=XXX HR=YYY
When NIBP data are displayed, the following format will appear:
SPO2=XXX HR=YYY SYS=SSS DIA=DDD MAP=MMM
where XXX is the SpO2 value, YYY is the heart rate value, SSS is the systolic value,
DDD is the diastolic value, and MMM is the MAP value. Essentially, whenever
NIBP data are available from the Avant 2120, that data will be displayed.
If there are no data from the oximeter, the formats will appear as follows:
SPO2=--- HR=--SPO2=--- HR=YYY SYS=SSS DIA=DDD MAP=MMM
The Avant 2120 includes an event marker feature. Events are indicated by a single
“*” whenever ON/STANDBY is pressed to go into Battery Capacity Display
mode. (ON/STANDBY may be pressed again to exit, or Battery Capacity Display
mode will time out after approximately 10 seconds.) This feature can be used to
mark exceeded alarm limits, or in other situations as desired.
