  • An error code appears in the display area.
    1. Turn the unit off and back on again to remove error code.
    2. If the error persists, disconnect battery & AC, and then reconnect the power and turn unit on.
    3. The device encountered an error. See “Error Codes Table” in your manual.
  • The NIBP cuff overinflates and detaches from either the device or the hose; blood pressure readings are not displayed.
    1. Ensure that the cuff is applied and positioned correctly. See “NIBP Cuff Selection” and “NIBP Cuff Placement” in your manual for more information.
    2. Ensure that the appropriate cuff size is selected.

    1. Press the Alarm Silence button to activate alarm volume, or wait for two minutes, the alarm tones will automatically activate.
    2. Adjust the alarm volume, or return option switch 2 to the DOWN position if audible alarms are required.
  • The device will only operate when it is plugged in.
    1. Plug in the AC Power Supply to charge the battery.
    2. Check that the battery pack is properly connected to device.

NIBP Calibration

Calibration should be performed after every 10,000 inflations or once per year, using the following procedure. Calibration should only be performed by qualified personnel.

Suggested Equipment

  • Mercury Manometer
  • Pneumatic T-Adapter
  • Pressure Bulb

With the device turned off, connect a mercury manometer and pressure bulb to the device using a T-adapter.

  1. using the tip of a screwdriver or other similar device, place DIP switch ‘n the UP position.
  2. Turn on the device A CAL message displayed in the Systolic display window, verifying that the device is In Calibration mode.
  3. Watt for a green to appear in the Diastolic LED display.
  4. Verify that the pressure on the manometer is zero, so there is no pressure difference at the pressure transducer and outside the device.
  5. Press the NIBP button. A countdown Will begin. fOllowed by “250” in the Diastolic display.
  6. Using the pressure bulb, apply exactly 250 mmHg to the device.
  7. Press the NIBP button to calibrate the device at 250 mmHg. The device is now calibrated and Will displaya ca I cine message.
  8. Press the OWSTANDBY button to turn the device off. Return DIP switch 1 to the DOWN position.

NOTE: The pulse oximeter does not require calibration_

Error Codes

Code Description
 CAN NIBP Module, User Cancelled – The NIBP module was cancelled from taking a blood pressure reading.
E00 System Error – Retry reading.  If reading is not possible, then cycle power and retry.  Calibration may be required.
E01 NIBP Module, Bad Signals – The NIBP module was unable to complete a reading.  The failure could be due to a patient’s blood pressure falling outside the module’s range.  Check the patient, the air hose connection, and application of the cuff.

Frequently Asked Questions

How is the cuff inflation pressure determined?

The Avant 2120 default initial inflation pressure is 160 mmg, this value can be changed by pressing the Pressure Limit button and selecting the desired pressure. Each subsequent inflation will be dynamically determined by the Avant 2120. The previous Systolic reading will be increased by 25-30 mmHg for the next inflation.

What is the maximum inflation pressure for a reading?

The Avant 2120 will inflate to a pressure of 260 mmHg; if there is a failure and the system exceeds that pressure, the system will automatically deflate the cuff or the device will shut down dependent upon the reason for the failure.

What is the maximum and minimum pressure range the Avant 2120 is able to measure?

The range is 260-10 mmHg.

What does the MAP value represent?

The mean arterial pressure (MAP) is a calculated value that is equal to one third of the Systolic pressure plus two thirds of the Diastolic pressure. It represents the mean pressure which would be required to maintain arterial patency for appropriate blood circulation.

How do you cancel a blood pressure reading?

Press any button on the front panel during a reading.

How can the pulse rate be displayed if only blood pressure is measured?

The pulse rate will be derived from the pulsations of the NIBP oscillometric waveform.

What is the overall length of the blood pressure cuff hose?

Six (6) feet (2m).

How long will the blood pressure reading remain on the display?

Five (5) minutes.

How many blood pressure readings will be saved for review during one power-up period?

Up to 300 readings will be stored in the volatile memory for review. The pressure displays will change from green to amber to indicate history review.

How do you review previous blood pressure readings?

Press the History Review button. The most recent previously measured reading will appear on the screen. The number of the reading will appear in the same field as the inflation pressure. To move through the saved readings, press the minus (-) button or (+) button as needed.

When blood pressure history is reviewed the timer shows the number saved reading; does that mean the timer has been reset?

No, the elapsed time from the most recent reading is still being timed.

Cant the blood pressure module be calibrated?

Yes.

To calibrate, the blood pressure module dipswitch #1 must be in the on or up position. Follow the instruction for calibration found in the Avant 2120 Operator’s Manual. The blood pressure module should be calibrated every 10,000 inflations or once per year.

Can the Avant 2120 NIBP module be used with adult and pediatric patients?

Yes, the NIBP may be used for patiens with arm circumferences of 18-42 cm. Care should be taken to ensure the proper cuff size and appropriate inflation pressure is selected.

How do you retain the last User selected alarm settings?

While turning the unit on, continue to hold the On/Standby button while pressing and holding the Alarm Limits button for at least one second.

If the Avant 2120 was powered up without an SpO2 sensor connected, does the unit have to be restarted to use the oximetry function?

No, simply connect the sensor to the unit and it will be ready to include the pulse oximetry readings.

How many hours of pulse oximetry data can be stored in the non-volatile memory for download?

Up to 33.5 hours of pulse rate and SpO2 data may be stored. nVision software may be used to retrieve and analyze the data.

What is the longest overall oximeter cable that can be used with the Avant 2120?

The recommended overall maximum length of sensor cable including extension cable is 40 feet (12m).

Does the oximeter require calibration.

No calibration is required.

Can the Avant 2120 oximetry module be used with neonates?

The pulse oximeter function may be used for neonates through adult patients; Nonin offers a complete line of patient sensors to accommodate every application.

How many dipswitches does the Avant 2120 have and what are they used for?

There are eight (8) numbered dipswitches. Dipswitches 1, 2, and 3 are currently assigned for use.

#1 activates calibration of the blood pressure module, #2 allows the alarm volume to be set to 0 and #3 changes the date format. Please refer to the Avant 2120 Operator’s Manual for additional information.

Where are the dipswitches located on the Avant 2120?

They are underneath the green battery door cover on the rear of the unit. Use a small Phillips screwdriver to remove the battery door. Please refer to the Avant 2120 Operator’s Manual for additional information.

What is the warranty on the Avant 2120?

Blood Pressure Module and Battery Pack – 1 Year

Oximetry Module – 3 Years

How long can the Avant 2120 function on a fully charged battery?

  • Continuous SpO2 monitoring and NIBP readings every minute – 5 hours minimum
  • Continuous SpO2 monitoring and NIBP readings every 5 minutes – 6 hours minimum

How long does it take to recharge the battery pack?

Approximately four hours if they are completely discharged and the system is not in use. The battery pack continuously charges while the device is plugged into AC power, charging will be longer if the system is in use.
