2.4 Usage of Patient Circuit • For the Vivo 55 to deliver treatment according to settings, it is important that the selection of the patient circuit type (see “Select Patient Circuit Type” on page 49) is correctly set. • Only use the Vivo 55 with accessories recommended by Breas Medical AB. • The pressurized air from the Vivo 55 causes a continuous flow of air to exhaust from the leakage ports or exhalation valve, flushing exhaled gas from the circuit. The Vivo 55 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 55 is turned on and operating properly. • Do not use patient hoses or tubes made of static or electrically conductive material. • Always use a new patient circuit when the Vivo 55 is to be used by a new patient. • 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 is replaced or modified. • Patient connected parts and all filters must be replaced regularly to ensure correct function of the Vivo 55. All replaced parts must be disposed of according to local environmental regulations regarding the disposal of used equipment and parts. • Periodically check for moisture in the patient circuit. When present, remove the moisture. Before attempting to dry the circuit, disconnect it from the Vivo 55 to ensure no water flows back into the Vivo 55. The frequency at which these checks must be performed will depend on the patient’s own condition and the device used. You should assess this on an individual basis in accordance with the patient’s needs.
14 Safety Information Vivo 55 clinician’s manual
Doc. 006626 En-EU U-3
• When using the Vivo 55 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 “Performing the Pre-use Test” on page 35.) • 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 is never blocked or obstructed. • Do not leave long lengths of air tubing around the top of the bed. It could twist around the patient’s head or neck while he or she is sleeping. • Always follow the instructions of the mask manufacturer. • The Vivo 55 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. • To reduce the risk of rebreathing CO2, make sure that the leakage port or active exhalation valve is present as close as possible to the patient connection. • Contact Injuries: Skin irritation may occur due to prolonged exposure to either a mask (if used) or the SpO2 module. The Vivo 55 and its packaging do not contain any natural rubber latex.

Safety Information 15 Vivo 55 clinician’s manual
2.5 Usage of Filters • Always use the Vivo 55 with patient air inlet filters installed. Only use the Vivo 55 with accessories recommended by Breas. • Replace or clean the filters regularly to ensure correct function of the Vivo 55, especially when changing patients. Failure to replace or clean a dirty filter may cause the Vivo 55 to operate at higher temperatures than intended. A dirty filter may be caused by dust or animal hair in the home environment. • When operating the Vivo 55, make sure that the air inlet and filters are not obstructed or occluded. • If the Vivo 55 is used in a clinic by several patients, a low resistance bacterial filter is recommended between the air outlet and the patient circuit to prevent patient cross-contamination. (Breas recommends the low resistance bacterial filter part no. 004185.) Reuse of a mask or bacterial filter may expose patients to contagious agents. • The use of a high resistance bacterial filter on the output of the device 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 “Performing the Pre-use Test” on page 35.) • When adding or removing any kind of filter, always perform a preuse test.
16 Safety Information Vivo 55 clinician’s manual
Doc. 006626 En-EU U-3
2.6 Humidification • Humidification must only be used if this has been prescribed by a physician. • 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 a humidifier or nebulizer, any patient air filter will need more frequent replacement to prevent increased resistance or blockage. • During transportation of the Vivo 55, 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 condensated water in the patient circuit from running into the patient airways and causing personal injury. • When adding or removing a HME (Heat and Moisture Exchanger, artificial nose) or HCH (Hygroscopic Condenser Humidifier), always perform a pre-use test. • Any humidifier connected to the Vivo 55 must comply with ISO 8185. • Any HME connected to the Vivo 55 must comply with ISO 9360. • The use of an HME or an external humidifier may require readjustment of the Vivo 55 low-pressure alarm. • Certain HMEs and HCHs are sufficient to provide humidification when the Vivo 55 is used invasively. Check specific suppliers’ recommended use.

Safety Information 17 Vivo 55 clinician’s manual
2.7 Cleaning and Maintenance • The Vivo 55 should be cleaned and maintained in accordance with this operating manual. (See “Cleaning and Maintenance” on page 163.) • Do not attempt to autoclave or sterilize the Vivo 55 main unit. • The Vivo 55 should undergo maintenance, service and control procedures, as well as any applicable upgrades, in accordance with Breas service instructions. • The Vivo 55 shall only be repaired or modified in accordance with Breas service manuals, technical bulletins, and any special service instructions, by service technicians authorised by Breas Medical AB. • Do not under any circumstances attempt to open, service or repair the Vivo 55 yourself. If you do so, the manufacturer will no longer be responsible for the performance and safety of the Vivo 55. Furthermore, no guarantees will be valid.
18 Safety Information Vivo 55 clinician’s manual
Doc. 006626 En-EU U-3
2.8 Usage of Oxygen • Always follow the oxygen provider’s instructions. • The presence of oxygen can speed up combustion of inflammable materials. • At a fixed flow rate of supplemental oxygen flow, the inhaled oxygen concentration will vary, depending on the pressure delivered, the patient’s breathing pattern, mask selection and leak rate. To monitor the oxygen concentration the FiO2 sensor (part no. 006347) is recommended. • When oxygen is used with the Vivo 55, the oxygen flow must be turned off when the Vivo 55 is not operating. Oxygen delivered into the patient tubing may accumulate within the machine enclosure. Oxygen accumulated in the machine enclosure will increase the risk of fire. • Do not use a humidifier between the oxygen source and the ventilator, in order to humidify the oxygen flow. • Ventilate the room adequately. • Do not smoke in a room where oxygen is being used. • Naked light bulbs and other sources of ignition must be kept a minimum of 2 metres away from the oxygen cylinder or any part of the patient circuit. • Supplemental oxygen with a flow up to 15 l/min can be added by an oxygen source with rotameter such as oxygen cylinder, central oxygen supply system or an oxygen concentrator. • Do not use aerosols or solvents close to the oxygen supply, even when the oxygen supply is shut off.
Doc. 006626 En-EU U-3
Safety Information 19 Vivo 55 clinician’s manual
• Supplemental oxygen flow must not exceed 15 l/min. or 100 kPa. • The oxygen concentration in the delivered air has influence on the volume measurement of the Vivo 55. This measurement is based on a normal oxygen concentration of 21%. If the oxygen concentration is higher, the monitored inspired volume will deviate from the actual volume as follows: – 40% oxygen concentration: -2.5% deviation – 60% oxygen concentration: - 5% deviation – 80% oxygen concentration: -7.5% deviation
