Intended use of the HA 20 Humidifier • Read this manual thoroughly so that you completely understand how the HA 20 Humidifier is operated and maintained before taking it into use, to ensure correct usage, maximum performance and serviceability. • Also read the Breas breathing therapy equipment manual, before you install the HA 20 Humidifier. Breas Medical AB reserves the right to make changes to this product without any prior notification.
1.1 What is the HA 20 Humidifier? The Breas HA 20 is an integrated humidifier intended to increase the breathing comfort for patients using Breas breathing therapy equipment. It is connected to the Breas iSleep or Vivo device through a smooth click-on design. Under normal conditions, the nose and the airways keep the air we breathe in sufficiently humid. When using a CPAP device or ventilator, the normal humidification may not be sufficient. When the air you breathe in is too dry, you may suffer from dryness of the nose, throat or mouth, and from mucus build up, which in turn may cause pain, irritation or infection. Humidified air may relieve these symptoms of dry airways.
1.2 Indications for Use The HA 20 Humidifier is intended to humidify the patient air during breathing therapy. It is intended for non-invasive use only. The HA 20 Humidifier can only be used together with the following breathing therapy equipment: • Breas CPAP devices: iSleep 20, iSleep 20+, iSleep 20i, iSleep 22, and iSleep 25 • Breas Bilevel ventilators: Vivo 30 and Vivo 40
It must always be prescribed by a licensed physician. For complete instructions on how to set up the humidifier, refer to the Breas breathing therapy equipment manual.

Safety Information
2.1 General User Precautions • The HA 20 Humidifier must only be used: – for the intended treatment in accordance with this manual and with the instructions given by the responsible clinical personnel; – in accordance with the operating conditions specified in this manual; – in original and unmodified shape and only with accessories specified or approved by Breas Medical AB.
• Do not use the HA 20 Humidifier if the patient’s upper (supraglottic) airways have been bypassed. • Never operate the HA 20 Humidifier if it is not working properly, if any part of the humidifier has been dropped or damaged, or the heating unit has been submerged in water. In the event of suspected damage to the HA 20 Humidifier, do not use the humidifier and contact the responsible care provider or service provider for an inspection. • The installed HA 20 Humidifier must be located below the patient and on a flat surface. This is to prevent personal injury from accidental spillage or from excess water or condensation flowing down the patient tube and into the patient’s mask. Extra cautions should be taken for patients who are unable to guard their airways or cannot pull off the mask. • Periodically check for moisture in the patient circuit. When present, remove the moisture. Before attempting to dry the circuit, disconnect it from the HA 20 Humidifier to ensure no water back-flow into the humidifier. The frequency at which these checks must be performed will depend on the patient’s own condition and the device used. This should be assessed on an individual basis in accordance with the patient’s needs. • If the condensation in the patient circuit is excessive, the use of a heated humidifier may require the installation of a water trap in the circuit. The water trap prevents any condensation in the patient circuit from running into the patient airways and causing personal injury. • Do not connect any filter to the HA 20 Humidifier.

Safety Information 5 Breas HA 20 Humidifier User Manual
• Handle the HA 20 Humidifier with care. • To avoid burn injury, be careful not to touch the heater plate or the heated water in the water chamber when the HA 20 Humidifier is switched on or has not yet cooled down. Wait ten minutes for the heater plate and water to cool. • Before transportation of the Breas breathing therapy equipment with the installed HA 20 Humidifier, always disconnect the water chamber from the heating unit. • Do not place the Breas breathing therapy equipment with the HA 20 Humidifier in a bag when the water chamber is attached. • Do not use aromatic additives (such as scented oil or perfume) with the water, as the may reduce the humidification effect and cause deterioration of the water chamber.
2.2 Electrical Safety When handling the HA 20 heating unit, always turn off and disconnect the Breas breathing therapy equipment from any power source.
2.3 Environmental Conditions • The performance of the HA 20 Humidifier may deteriorate at: – ambient temperatures below 5°C (41°F) and above 40°C (104°F). – ambient relative humidity below 10% RH (room humidity) and above 95% RH. – atmosphere pressure below 700 mbar and above 1060 mbar. At normal atmospheric pressure, 700 mbar =~3000 metres above sea level, 1060 mbar = ~375 metres below sea level.
• The HA 20 heating unit, water chamber and any replaced parts must be disposed of in accordance with the local environmental regulations regarding the disposal of used equipment and waste.

For complete instructions on how to set up the humidifier, refer to the Breas breathing therapy equipment manual. The most ideal setting is dependant on the ambient temperature and humidity. This implies that the ideal setting may vary due to seasonal temperature changes. If the room temperature gets very cold during the night, a lower setting may be necessary to prevent condensation in the tubes. If the overnight temperature remains high, a higher setting may be more comfortable. A HA 20 Humidifier filled to the maximum level will be able to humidify the air for 12 hours with the following settings and conditions:
