3. ACCEPTANCE/PERFORMANCE CHECKS

This section contains performance checks which can be carried out on the AIRVO 2, however there is
no manufacturer requirement to carry out these checks on a routine basis. These checks test the basic
functions of the unit, the operation of the flow sensor and the audible alarm signal.

SENSOR CHECKS

To ensure quality and patient safety, Fisher & Paykel Healthcare undertakes stringent testing to each
and every unit manufactured. The AIRVO 2’s sensors, measuring temperature, flow and oxygen, have
been carefully designed to exacting criteria, and are calibrated and tested in our controlled work
environment to strict limits. Furthermore, the AIRVO 2 itself carries out regular self-checks during
normal use, comparing sensor readings against expected values.

Do not perform additional tests of internal sensor accuracy, as these often produce erroneous
results due to limitations of the external test environment and equipment used, particularly given the
temperature, humidity content and/or flow of the gases being delivered by the AIRVO 2.

ACCEPTANCE/PERFORMANCE CHECKS

The acceptance/performance checks should be conducted under the following ambient conditions:
Temperature: 22 ± 2°C, Humidity: 50 ± 5% RH.

The following equipment is required:

AIRVO 2 humidifier MR290 chamber

(or alternatively a
HC360 chamber)

Heated breathing tube

(from 900PT500 or
900PT501 kit)

Nasal interface

(OPT842, OPT844 or
OPT846)

A. HEATERPLATE TEST

1. Add 150 mL of room temperature (not hot) water to the water chamber and fit the chamber onto the
heater plate of the device. Fit the chamber tightly on to the chamber ports.

2. Connect the heated breathing tube to the Heated Breathing Tube Connection port. Connect the nasal
cannula interface to the heated breathing tube.

3. Turn on the device, by pressing the power button for 2 seconds. Warm-up bars will be displayed as the
unit warms up. Ensure the flow is set to 30 L/min.

4. Check that the “Ready for use” symbol (a “tick” or “check”) is displayed within 30 minutes.

B. “CHECK FOR LEAKS” TEST

After the “Ready for use” symbol is displayed, the “Check for leaks” sensor test can be tested as follows:

1. Remove the chamber completely from the unit.

2. Check that the display shows the “Check for leaks” error (in the appropriate language) and that the
audible alarm sounds, within 2 minutes.

3. Reconnect the chamber and check that this flashing display disappears, the audible alarm stops and the
display reverts back to the Warm-up/Ready-for-use screen.

13

C. “CHECK FOR BLOCKAGES” TEST

After completing the “Check for leaks” test, the “Check for blockages” test can be tested as follows:

1. Disconnect the cannula from the Heated Breathing Tube.

2. Completely block the end of the Heated Breathing Tube with your hand.

3. Check that the display shows the “Check for blockages” error (in the appropriate language) and that the
audible alarm sounds, within 30 seconds.

4. Unblock the end of tube and check that this flashing display disappears, the audible alarm stops and the
display reverts back to the previous display.

5. Reconnect the cannula to the Heated Breathing Tube.

D. “CHECK TUBE” TEST

After completing the above flow tests, the Tube Missing alarm can be tested as follows:

1. Remove the Heated Breathing Tube (pull the blue sleeve up first).

2. Check that within 10 seconds the display flashes the Breathing Tube symbol and the alarm sounds.

3. Refit the Heated Breathing Tube, check the alarm stops and that the display reverts back to the previous
display.

Note: If any of the tests above fail, please contact your Fisher & Paykel Healthcare representative.

D.12 Condensation

D.12.1 PREVENTION OF EXCESSIVE CONDENSATION

A. Is the AIRVO 2 being used in ambient conditions between 18 – 28 °C
(64 - 82 °F)?

B. Is the AIRVO 2 placed below head height

C. Is there a local source of cooling acting on the heated breathing tube?

D.12.2 CONDENSATION MANAGEMENT

A. Implement a system to check the heated breathing tube for condensate

B. If condensation is present, drain it back into the water chamber

C. If condensate persists, consider turning the target temperature down.

D.12 Condensation

D.12.1 PREVENTION OF EXCESSIVE CONDENSATION

A. Is the AIRVO 2 being used in ambient conditions between 18 – 28 °C
(64 - 82 °F)?

• If the room is less than 18 °C (64 °F), condensation is more likely to
occur.

B. Is there a local source of cooling acting on the heated breathing tube?

• A fan to cool the patient,

• An air-conditioning unit, vent or an open window?

• Are you able to remove or minimize these sources of cooling, e.g.
redirect the fan, cooling the patient, away from the heated breathing
tube?

D.12.2 CONDENSATION MANAGEMENT

A. Implement a system to check the heated breathing tube for condensate

regularly.

B. Is the AIRVO 2 placed below head height

Fig. 21

?

• This will allow condensate to drain towards the water chamber, away
from the patient.

C. If condensation is present, drain it back into the water chamber

Fig. 22

:

• Disconnect the patient interface from the heated breathing tube.

• Drain the tube by lifting the patient end of the tube, allowing the
condensate to run into the water chamber.

• At higher target flow rates, it may be necessary to first reduce the target
flow rate to 30 L/min or below, to ensure the condensate drains into the
water chamber.

D. If condensate persists, consider turning the target temperature down.

• A lower target temperature will decrease the humidity output of the
AIRVO 2, decreasing the level of condensation.
Note: The temperature and humidity level delivered to the patient will also
be reduced.
