1. Introduction
The Airvo 3 is designed to deliver Optiflow™ high flow therapy to spontaneously breathing patients.
A blower inside the Airvo 3 entrains flows of room air of 2–70 L/min, which may be blended with oxygen from high-pressure sources
(such as wall supplies or bottles) or low-pressure sources (such as flowmeters). The air-oxygen mixture is then warmed and humidified in
the water chamber, before being transported through the heated breathing tube to a nasal, tracheostomy or mask patient interface.
The Airvo 3 is powered by wall power supply, with internal battery backup to provide continuity of therapy during intra-hospital transport.
1.1 Intended use/indications for use
The Airvo 3 is for the treatment of spontaneously breathing patients who would benefit from receiving high flow warmed and humidified
respiratory gases. This includes patients who have had upper airways bypassed. The flow may be from 2–70 L/min depending on the
patient interface. The Airvo 3 is for patients in hospitals and sub-acute facilities.
The Airvo 3 can deliver these high flow gases through nasal cannula to augment the breathing of spontaneously breathing neonate, infant,
child, adolescent and adult patients suering from respiratory distress and/or hypoxemia in the hospital setting. The Airvo 3 is not
intended to provide total ventilatory requirements of the patient and is not for use during field transport.
1.2 Contraindications
Contraindications are therapy-specific. Refer to instructions of patient interfaces and/or tube and chamber kits for therapy-specific
contraindications.
1.3 Side-eects
Side-eects are therapy-specific. Refer to instructions of patient interfaces and/or tube and chamber kits for therapy-specific side-eects.
2. Safety information
The Airvo 3 and accessories are to be operated by, or under the supervision of, qualified personnel only. Read this manual and the

Airvo 3 - USER MANUAL | A - 15
English
4.3 Supplementary oxygen
Low-pressure
oxygen (LPO) port
High-pressure
oxygen (HPO) port
The Airvo 3 provides two options for connecting
supplementary oxygen:
1. A high-pressure oxygen (HPO) inlet port, and
2. A low-pressure oxygen (LPO) inlet port.
The high-pressure oxygen inlet port is connected to the wall oxygen supply or
to the pressure regulator on an oxygen bottle. The ability of the Airvo 3 to
provide the target FiO2is limited by the line pressure of the high-pressure
inlet port (HPO). If the Airvo 3 is unable to maintain the target FiO2, the device
will generate a “FiO2Below Target” alarm.
The low-pressure oxygen inlet port is connected to an external flowmeter,
typically a rotameter.
Warnings
You must take special care when using supplementary oxygen to reduce the risk of fire. Keep all sources of ignition away from the
Airvo 3 and, preferably, not in the same room as the Airvo 3 during use.
Do not use supplementary oxygen while smoking, near sparks or open flames.
When using bottled oxygen, ensure the volume remaining in the bottle is sucient for the therapy planned.
Connect only pure oxygen gas to the oxygen inlet ports on the Airvo 3. The oxygen concentration displayed will be wrong if any
other gas, or mixtures of gases, is connected.
The oxygen concentration delivered to the patient can be aected by changes to the oxygen setting, patient interface or
obstructions in the air path.
Only use lotions and/or salves that are labeled as oxygen-compatible to avoid the risk of fire and burns.
Appropriate patient monitoring must be used at all times.
Make sure that all oxygen connectors are tightened suciently to prevent leaks.
As the low-pressure oxygen (LPO) inlet port uses an alternative small-bore connector design dierent from those specified in the
ISO 80369 series, there is a possibility that a misconnection can occur with a medical device using a dierent alternative
small-bore connector, which can result in a hazardous situation causing harm to the patient. Special measures need be taken by
the user to mitigate these reasonably foreseeable risks.
During Optiflow high flow therapy, the fraction of oxygen inspired by the patient will be lower than the value displayed on the FiO2
tile if the patient’s peak inspiratory demand exceeds the flow delivered.
Caution
Do not connect an oxygen supply to both the high-pressure oxygen inlet port and the low-pressure oxygen inlet port at the same time.
Using the low-pressure inlet at the same time as the high-pressure inlet may cause incorrect oxygen delivery and a FiO2Above Target
alarm.
Note
The built-in oxygen analyzer uses ultrasonic measurement technology. It does not require in-field calibration.
4.3.1 High-pressure oxygen (HPO) source
When oxygen is connected to the HPO port, the Airvo 3 directly controls the oxygen input to meet the target FiO2setting.
Wall oxygen
supply

A - 16 | Airvo 3 - USER MANUAL
English
4.3.2 Low-pressure oxygen (LPO) inlet port
When using the LPO port, the amount of oxygen taken in by the Airvo 3 is controlled by an external
flowmeter. Connect a tube from the external flowmeter to the LPO port. Make sure that the flowmeter
is turned o whenever the Airvo 3 is not delivering therapy.
When using the low-pressure oxygen inlet port, monitor the oxygen concentration displayed on the
Home screen. The oxygen flow-regulator must be adjusted manually to maintain the prescribed
oxygen concentration when changing the respiratory gas flow rate.
Clinicians may configure a High FiO2alarm to discourage use of high FiO2values in particular clinical
environments.
The High FiO2alarm can be disabled or a threshold between 30% and 95% can be selected when the
Airvo 3 is initially set up for your environment (see Oxygen high alarm threshold, Airvo 3 Technical
Manual). The alarm threshold is displayed on the Titrate FiO2screen, if enabled. Tap the FiO2tile to
open the Titrate FiO2screen.
5. Using the Airvo 3
5.1 Getting started
Turn on the Airvo 3
Plug the Airvo 3 power cord into the wall power supply.
