Doc. 006150 D-1
Safety Information 17 Vivo 65 User manual
2.4
Usage of Patient Circuit WARNING! For the ventilator to deliver treatment according to settings, it is important that the selection of the patient circuit type (see 5.2.2 Symbols Used in the Menu, page 47)is correctly set. Only use the Vivo 65 with accessories recommended by Breas Medical. The pressurized air from the ventilator causes a continuous flow of air to exhaust from the leakage ports or exhalation valve, flushing exhaled gas from the circuit. If having a patient circuit with leakage port, the ventilator should be turned on and the function of the leakage port should be checked before use. The ventilator should be turned on and the function of the leakage port or exhalation valve should be checked before use. Do not breathe in the connected patient circuit unless the Vivo 65 is turned on and operating properly.
WARNING! Risk of Electric Shock Do not use antistatic or electrically conductive hoses or tubing with the ventilator breathing system. This could result in electrical shock.
WARNING! Always make sure that the patient circuit and joined parts are undamaged and correctly connected, in order to avoid unwanted leakage. Always perform a pre-use test when the patient circuit or insert is replaced or modified. Patient connected parts and all filters must be replaced regularly to ensure correct function of the ventilator. All replaced parts must be disposed of according to local environmental regulations regarding the disposal of used equipment and parts.
18 Safety Information Vivo 65 User manual
Doc. 006150 D-1
Risk of Suffocation Periodically check for moisture in the patient circuit. When present, remove the moisture. Before attempting to dry the circuit, disconnect it from the Vivo 65 to ensure no water flows back into the Vivo 65. The frequency at which these checks must be performed will depend on the patient’s condition and the device used. The responsible caregiver should assess this on an individual basis in accordance with the patient’s needs. When using the Vivo 65 invasively, the low volume alarm and the low breath rate alarm must be carefully set, to ensure safe use. The use of equipment such as endotracheal tubes, oral/nasal tubes, adaptors, etc. with small inner diameters or high resistance filters (such as humidifiers) increases the resistance in the patient circuit which may interfere with the operation of the patient disconnect function. It may also interfere with the device trigger function. The impact can be reduced by conducting a pre-use test properly. (See 4.6 Performing the Pre-use Test, page 42.) In case of invasive application, the use of an appropriate external heated humidifier or HME (Heat and Moisture Exchanger, artificial nose)/HCH (Hygroscopic Condenser Humidifier ) is recommended. Make sure that the exhalation valve or the leakage port never is blocked or obstructed. Risk of Constriction Entanglement with cables or tubing constricting airways may cause asphyxiation. Do not leave long lengths of air tubing or cables around the top of the bed. They could twist around the patient’s head or neck while sleeping. Always follow the instructions of the mask manufacturer. The Vivo 65 is equipped with a rebreathing alarm. The alarm is not a substitute for operator vigilance in ensuring that the leakage port or exhalation valve remains clear at all times. Periodically check the patient circuit during therapy. In general, as pressure decreases, the potential of rebreathing increases. Lower pressures produce less flow through the leakage port which may not clear all CO2 from the circuit to prevent rebreathing.
Doc. 006150 D-1
Safety Information 19 Vivo 65 User manual
To reduce the risk of rebreathing CO2: • Single limb circuit use: make sure that the leakage port or active exhalation valve is present as close as possible to the patient connection. • Dual limb circuit use: make sure that the Y-piece is present as close as possible to the patient connection.
CAUTION! Contact Injuries: Skin irritation may occur due to prolonged exposure to either a mask (if used) or the SpO2 module.
WARNING! Always use a new patient circuit when the Vivo 65 is to be used by a new patient.
NOTE The Vivo 65 and its packaging do not contain any natural rubber latex.

Usage of Filters WARNING! Always use the ventilator with patient air inlet filters installed. Only use the ventilator with accessories recommended by Breas Medical. Replace or clean the filters regularly to ensure correct function of the Vivo 65. Failure to replace or clean a dirty filter may cause the Vivo 65 to operate at higher temperatures than intended. A dirty filter may be caused by dust or animal hair in the home environment. Risk of Insufficient Ventilation Insufficient ventilation may cause transient hypoxia. Replace or clean the inlet filters as specified in the Maintenance chapter. Using old or clogged filters may cause the Vivo 65 to operate at higher temperatures than intended. When operating the Vivo 65, make sure that the air inlet and filters are not obstructed or occluded.

Risk of Insufficient Ventilation Insufficient ventilation may cause transient hypoxia. The use of equipment such as endotracheal tubes, oral/nasal tubes, adaptors etc. with small inner diameters or high resistance filters, humidifiers etc. increase the resistance in the patient circuit which may interfere with the operation of the patient disconnect function. It may also interfere with the device trigger function. This impact can be reduced by conducting a pre-use test. When adding or removing any kind of filter, always perform a pre-use test.
2.6
Humidification WARNING! Humidification must only be used if this has been prescribed by your physician. The Vivo 65 therapy settings must always be prescribed by a physician or other licensed health care professional, and be carried out by authorized clinical personnel. When using an external heated humidifier, it should be located below the Vivo 55 and the patient to prevent injury from accidental spillage. When using the humidifier or a nebuliser any patient air filter will need more frequent replacement to prevent increased resistance or blockage. During transportation of the Vivo 65, the humidifier must be disconnected. 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 condensed water in the patient circuit from running into the patient airways and causing personal injury. When adding or removing an HME (Heat and Moisture Exchanger, artificial nose) or HCH (Hygroscopic Condenser Humidifier), always reassess the settings, including alarm settings, and perform a pre-use test. Any humidifier connected to the Vivo 55 must comply with ISO 8185 or 80601-2-74. Any HME connected to the ventilator must comply with ISO 9360.
