FISHER PAYKEL myAIRVO 2 Humidified High Flow Generator System User Manual

OVERVIEW

The myAIRVO 2 is a humidifier with integrated flow generator that delivers warmed and humidified respiratory gases to spontaneously breathing patients through a variety of patient interfaces.

INTENDED USE
The myAIRVO 2 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 – 60L/min depending on the patient interface. The myAIRVO 2 is for patients in homes and long-term care facilities. USA Federal Law restricts this unit for sale by or on the order of a physician.

WARNINGS

• Nasal delivery of respiratory gases generates flow-dependent positive airway pressure (PAP). This must be taken into account where PAP could have adverse effects on a patient.
• The unit is not intended for life support.

To avoid burns:

• The unit should only be used with interfaces, water chambers and breathing tubes specified in this user anual.
• Using the breathing tube or interface for longer than the specified time can result in serious injury including infection.
• Before using oxygen with the unit, read all warnings in the “Oxygen” section of this manual.
• Never operate the unit if:
• the heated breathing tube has been damaged with holes, tears or kinks,
• it is not working properly,
• the case screws have ever been loosened.
• Do not block the flow of the air through the unit and breathing tube.
• The unit should be located in a position where ventilation around the unit is not restricted.
• Never block the air openings of the unit or place it on a soft surface such as a bed or couch/sofa, where the filter area may be blocked. Keep the air openings free of lint, hair etc.

To avoid electric shock:

• Do not store or use the unit where it can fall or be pulled into water. If water has entered the unit enclosure, disconnect the power cord and discontinue use.
• Never operate the unit if:
• it has been dropped or damaged,
• it has a damaged power cord or plug,
• it has been dropped into water.
• Avoid unnecessary removal of the power cord from the rear of the device. If removal is necessary, hold the connector during removal. Avoid pulling on the power cord.
• Return the unit to an authorized service center for examination and repair, except as outlined in this manual. To avoid choking, or inhalation of a foreign object:
• Ensure an air filter is fitted when operating your unit.
• Never drop or insert any object into any opening or tube. Miscellaneous:
• Do not use the unit when the room temperature exceeds 30°C (86°F) or is below 10°C (50°F) as the unit may switch off. Humidity output will be compromised below 18°C (64°F) and above 28°C (82°F).
• The unit is not suitable for use in the presence of a flammable, anesthetic mixture with air or oxygen or nitrous oxide.

SETTING UP myAIRVO 2

1. BEFORE YOU BEGIN
   Place the unit on a low shelf or near the floor beside your bed. It must be placed below head height and flat.
   

2. INSTALL WATER CHAMBER
   IF USING A HC360 REUSABLE WATER CHAMBER:
   With the aid of the supplied funnel, fill the chamber with enough distilled water for the period of use, but never above the 560 mL fill line.
   

WARNINGS To avoid burns:

• Do not fill the water chamber with hot water. To avoid electric shock:
• Always remove the water chamber to fill it and always fill with enough distilled water to prevent it running out.

Fit the water chamber to the unit by pressing down the finger guard and sliding the chamber on, carefully aligning with the blue chamber port ends. Push the chamber on firmly until the finger guard clicks into place. Go to Step 3, “Install Heated Breathing Tube”, below.

IF USING THE MR290 AUTO-FILL WATER CHAMBER:
Remove the blue port caps from the chamber by pulling the tear tab upwards then remove the bracket holding the water supply tube. Fit the supplied adapter over the two vertical ports on the chamber and push on fully then clip the water supply tube into position. Fit the MR290 chamber as described above for the HC360 chamber. H2O

Attach the water bag to the hanging bracket at least 20cm (8”) above the unit, and push the bag spike into the fitting at the bottom of the bag. Open the vent cap on the side of the bag spike. The chamber will now automatically fill to the required level and maintain that level until the water bag is empty. Use only distilled water and always ensure sufficient water is in the water bag to prevent it from running out.

WARNINGS To avoid burns:

• Do not start the unit without the water chamber in place.
• Do not touch the heater plate, water chamber or chamber base during use.
• The water in the chamber becomes hot during use. Exercise caution when removing and emptying the chamber. To avoid electric shock:
• When handling the unit with the water chamber in place, avoid tilting the machine to prevent any chance of water entering the unit enclosure.
• Empty all the water from the water chamber before transporting the unit.

CAUTIONS
To ensure optimal therapy (MR290 only):

• Do not use the auto-fill MR290 chamber if it has been dropped, or been run dry and the “water out” alarm has been activated.

INSTALL HEATED BREATHING TUBE
One end of the heated breathing tube has a blue plastic sleeve. Lift the sleeve and slide the connector onto the unit. Push the sleeve down to lock.

WARNINGS To avoid burns:

• Do not modify the breathing tube or interface in any way.
• Do not allow the breathing tube to remain in direct contact with skin for prolonged periods of time.

To change the Day/Night setting:
Press the Up and Down buttons to choose the new setting.

COMPLIANCE

This screen displays three pieces of compliance data:

Total hours used| Displays the total number of hours that the unit has been switched on.
---|---
Hours per day| Displays the average number of hours that the unit has been used per day.
Checksum| Displays usage information for the medical practitioner.

JUNIOR MODE
If the patient will be using an Optiflow Junior nasal cannula (OPT316/OPT318), you must activate Junior Mode. Junior Mode limits the target settings to: 34 °C and 2 – 25 L/min, in increments of 1 L/min.

New target settings
The target settings for dew-point temperature and flow will be changed automatically. The colorful icons in the corners of the screen indicate that this unit is in Junior Mode.

To deactivate Junior Mode, follow the same procedure: hold the Mode button for 5 seconds.

OXYGEN
You can connect supplementary oxygen to the myAIRVO 2. Connect the output from the oxygen source to the oxygen inlet port on the back of the unit. Make sure you push the oxygen tube firmly onto this connection port. The fraction of oxygen you breathe with this air/oxygen mixture is determined by the airflow setting on the unit and the oxygen flow connected to the unit’s oxygen inlet port. The following table gives the approximate oxygen fraction delivered for the range of unit and oxygen airflows. The oxygen fractions given assume that the oxygen source is a home oxygen concentrator. These values will be higher if the oxygen source is bottled oxygen. At flows less than 10 L/min, the oxygen fraction delivered varies significantly with small changes in input oxygen flow. Oxygen flow settings should be titrated according to blood saturation levels.

It is important that the physician prescribing your oxygen therapy
approves both the flow and oxygen settings and that you do not adjust
these prescribed settings without consulting them. Check that suitable blood saturation levels are achieved at the prescribed flow.  Use continuous oxygen monitoring on patients who would desaturate significantly in the event of disruption to their oxygen supply.

WARNINGS
Before using oxygen with the unit, read all of the following warnings:

• The use of oxygen requires that special care be taken to reduce the risk of fire. Accordingly, for safety it is necessary that all sources of ignition be kept away from the unit and preferably out of the room in which it is being used.  Oxygen should not be used while smoking or in the presence of an open flame. The unit should be located in a position where ventilation around the unit is not restricted.
• A spontaneous and violent ignition may occur if oil, grease or greasy substances come in contact with oxygen under pressure. These substances must be kept away from all oxygen equipment.
• Do not connect more than 15 L/min O2 to the oxygen inlet port on the back of the unit.
• Ensure that the myAIRVO 2 is switched on before connecting oxygen.
• Oxygen must only be added through the special oxygen inlet port on the back of the unit. To ensure that oxygen enters the unit correctly, the oxygen inlet port must be fitted properly to the filter holder and the filter holder must be fitted properly to the unit. The power cord connector should also be well secured.
• The oxygen concentration delivered to the patient can be affected by changes to the flow setting, oxygen setting, patient interface or if the airpath is obstructed.

When finished, turn off the oxygen source. Remove the output of the oxygen source from the oxygen inlet port on the back of the unit.

WARNINGS To avoid burns:
The oxygen flow must be turned off when the unit is not operating, so that oxygen does not build up inside the device.

ALARMS
The myAIRVO 2 has visual and auditory alarms to warn you about interruptions to your treatment. These alarms are generated by an intelligent alarm system, which processes information from the sensors and target settings of the unit and compares this information to pre-programmed limits.
