1.1 What is the Vivo 40? The Vivo 40 is a pressure-supported and pressure-controlled ventilator. It has three modes of operation: PCV, PSV and CPAP. The PCV and PSV modes have an adjustable inspiratory trigger sensitivity setting which allows the patient to initiate ventilator-assisted breaths.

Doc. 003881 En-Uk Z-1

Intended Use of the Vivo 40 3 Vivo 40 clinician’s manual

• In the PCV mode (Pressure Control Ventilation), the ventilator provides assisted or controlled pressure-regulated breathing. In PCV mode the clinician sets an inspiration time. The inspiratory pressure is set by the IPAP setting. The end-expiratory pressure is set by the EPAP setting. • In the PSV mode (Pressure Support Ventilation), the ventilator’s expiratory trigger can also be adjusted allowing the ventilator to more easily match each patient’s needs. The inspiratory pressure is set by the IPAP setting. The end-expiratory pressure is set by the EPAP setting. • In the CPAP mode (Continuous Positive Airway Pressure), the ventilator provides a continuous positive airway pressure.

The Vivo 40 has a pressure sensor that continuously monitors output pressure to the patient and reference ambient pressure, so that the device automatically will compensate for altitude changes. The internal memory of the Vivo 40 can be downloaded to a PC where you can view the patient compliance data in the Breas Vivo PC Software. For more information about the Breas Vivo PC Software, please contact your Breas representative.

1.2 Indications for Use The Vivo 40 is not intended for life support or life-sustaining applications or for transport of critical care patients. The Vivo 40 shall only be used by patients with spontaneous breathing. The Vivo 40 is designed for patients who require long-term support by mechanical ventilation during night and part of the day, up to a maximum of 20 hours of use per day. The Vivo 40 is intended for non-invasive use, or invasive use with appropriate patients. The Vivo 40 can be used in clinical settings (e.g., hospitals, sleep laboratories, sub-acute care institutions) and home environments. It must always be prescribed by a licensed physician. The Vivo 40 is intended for treatment of both adult and paediatric (who weigh more than 10 kg) patients.

2.4 Usage of Patient Circuit • Only use the Vivo 40 with a mask, patient tube and leakage port recommended by Breas Medical AB and your health care professional. • The Vivo 40 requires a leak port instead of an actively controlled exhalation valve to remove exhaled gases from the patient circuit. Therefore, specific masks and patient circuits using a leakage are required for normal operation. The pressurized air from the Vivo 40 causes a continuous flow of air to exhaust from the leak ports, flushing exhaled gas from the circuit. The Vivo 40 should be turned on and the leak ports should be checked before application. • Do not breathe in the connected patient circuit unless the Vivo 40 is turned on and operating properly. • Do not use patient hoses or tubes made of static or electrically conductive material. • Always use a new mask, tube and leakage port when the Vivo 40 is to be used by a new patient. • Patient connected parts and filter must be replaced regularly to ensure correct function of the Vivo 40. 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 40 to ensure no water will flow back into the Vivo 40. 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. • If the patient is using a full face mask (covering mouth and nose), the mask must be equipped with a safety entrainment valve.

Safety Information 11 Vivo 40 clinician’s manual

• Make sure that the leakage ports are never blocked or obstructed. These ports are used to prevent re-breathing of exhaled air. Re-breathing of exhaled gases for longer than several minutes can, in some circumstances, lead to suffocation. • At low CPAP pressures, the air flow through the leakage ports may be inadequate to clear all exhaled gases. Some re-breathing may occur. • 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 sleeping. • Always follow the instructions of the mask manufacturer.

12 Safety Information Vivo 40 clinician’s manual

Doc. 003881 En-Uk Z-1

2.5 Invasive Use • For invasive applications, assure that an intentional leakage port is present in the circuit, as close as possible to the patient connection, to reduce the risk of rebreathing CO2. • When using the Vivo 40 invasively the low volume alarm and the low breath rate alarm must be carefully set, to ensure safe use. • The highest output from the HA01 humidifier is 30 mgH2O/litre, which means that it does not fulfill the humidifier standard for invasive use. • The Vivo 40 is equipped with a low leakage alarm. The low leakage alarm is not a substitute for operator vigilance in ensuring that the leakage ports remains clear at all times. Periodically check the leakage ports during therapy. • In general as pressure decreases the potential of rebreathing increases. Lower pressures produce less flow through the leakage ports which may not clear all CO2 from the circuit to prevent rebreathing. • In general as inspiratory time increases the potential of CO2 rebreathing increases. A higher inspiratory time decreases the expiratory time allowing less CO2 to be cleared from the circuit before the next breath. I:E ratios close to 1:1 increase the potential of CO2 rebreathing. • Endotracheal tubes, oral/nasal tubes etc with small inner diameters increase the resistance in the breathing circuit. • An external heated humidifier approved for invasive use or an appropriate HME (Heat and Moisture Exchanger, artificial nose)/HCH (Hygroscopic Condenser Humidifier) is recommended.

Safety Information 13 Vivo 40 clinician’s manual

2.6 Usage of Filters • Always use the Vivo 40 with patient air inlet filters installed. Only use filters that are specified in this manual. • Replace or clean the filters regularly to ensure correct function of the Vivo 40, especially when changing patient. Failure to replace or clean a dirty filter may cause the Vivo 40 to operate at higher temperatures than intended. • When operating the Vivo 40, make sure that the air inlet and filters are not obstructed or occluded. • If the Vivo 40 is used in a clinic by several patients, a low resistance bacteria filter is recommended between the air outlet and the patient circuit to prevent patient cross-contamination. Breas Medical AB recommends the usage of the Vital-Signs 303 Respirgard-II Filter. Reuse of mask or bacteria filter may expose patients to contagious agents. • The use of a high resistance bacteria 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. • Do not connect any filter to the HA 01 humidifier.

14 Safety Information Vivo 40 clinician’s manual

2.7 Humidification • The HA 01 humidifier is intended for non-invasive use only. • The humidifier shall be disconnected from the Vivo 40 during transportation. The Vivo 40 shall not be placed in the bag with the HA 01 humidifier attached. • When using an external heated humidifier, it should be located below the Vivo 40 and the patient to prevent injury from accidental spillage. • 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. The use of an HME (Heat and Moisture Exchanger, artificial nose) or an external humidifier may require readjustment of the Vivo 40’s low-pressure alarm. • Certain HME’s and HCH’s (Hygroscopic Condenser Humidifiers) are sufficient to provide humidification when the Vivo 40 is used invasively. Check specific suppliers recommended use.

2.8 Cleaning and Maintenance • The Vivo 40 should be cleaned and maintained in accordance with this operating manual. • Do not attempt to autoclave or sterilise the Vivo 40. • Vivo 40 should be subjected to maintenance, service and control and any applicable upgrades, in accordance with Breas service instructions. • Vivo 40 shall only be repaired or modified in accordance with Breas service manuals, technical bulletins, and any special service instructions, by service technicians authorized by Breas Medical AB. • Do not under any circumstances attempt to service or repair the Vivo 40 yourself. If you do so, the manufacturer will no longer be responsible for the performance and safety of the Vivo 40. Furthermore, no guarantees will be valid.

2.10 Usage of Oxygen • The presence of oxygen can speed up combustion of inflammable materials. • If oxygen has been prescribed, connect the oxygen supply tube to the appropriate oxygen port of the nasal mask or breathing system connector. • At a fixed flow rate of supplemental oxygen flow, the inhaled oxygen concentration will vary, depending on the pressure delivered, patient’s breathing pattern, mask selection, and leak rate. • When oxygen is used with the Vivo 40, the oxygen flow must be turned off when the Vivo 40 is not operating. • 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. • Do not use aerosols or solvents close to the oxygen supply, even when the oxygen supply is shut off. • When the Vivo 40 is not in operation, and the oxygen flow is left on, oxygen delivered into the patient tubing may accumulate within the machine enclosure. Oxygen accumulated in the machine enclosure will create a risk of fire. • Supplemental oxygen may trigger the low leakage alarm prematurely. • Supplemental oxygen flow may not exceed 15 l/min. • Supplemental oxygen affects the accuracy of the volume and flow measurements. It is not recommended to use supplemental oxygen when target volume is active.
