The Vivo 45 LS ventilator (with or without the SpO2 and CO2 sensors) is intended to provide continuous or intermittent ventilatory support for the care of individuals who require mechanical ventilation. Specifically, the ventilator is applicable for pediatric through adult patients weighing more than 5 kg (11 lbs.), however, the mouthpiece ventilation and Auto EPAP modes are only for adult patients during non-invasive ventilation.
The Vivo 45 LS with the SpO2 sensor is intended to measure functional oxygen saturation of arterial hemoglobin (%SpO2) and pulse rate.
The Vivo 45 LS with the CO2 sensor is intended to measure CO2 in the inspiratory and expiratory gas.
The device is intended to be used in home, institution, hospitals and portable applications such as wheelchairs and gurneys. It may be used for both invasive and non-invasive ventilation. The Vivo 45 LS is not intended to be used as an emergency transport or critical care ventilator. The Auto EPAP feature is for use with PSV+TgV+AE mode in hospital use only.
The Vivo 45 LS Ventilator is a portable, microprocessor controlled turbine based pressure support, pressure control or volume controlled ventilator intended for the care of individuals who require mechanical ventilation.
Flow and pressure are read using flow and pressure sensors. Essential parameters such as pressure, flow and volume are presented on the ventilator screen, both in the form as graphs and numbers.
Operator actions are performed via the front panel where the buttons and an LCD screen are located (and two dedicated buttons on the top of the ventilator control starting/stopping treatment and pausing the alarm audio). There are dedicated LEDs and buttons for managing alarm conditions and an Information button which provides integrated user support.
The Vivo 45 LS can be operated by external AC or DC power supply and contains an integrated battery as well as an optional click in battery.
The Vivo 45 LS can be used with two types of patient circuits: single limb patient circuits including an active exhalation valve and single limb patient circuits including a passive leakage port.

Technological Characteristics Compared to Predicate
Breas Medical's Vivo 45 LS is a modification to Breas Medical's previously cleared Vivo 45 LS (K193586) which is the primary predicate device. The Trilogy Evo (K181166) is the secondary predicate device for the AutoEPAP mode and the flow trigger.
The Vivo 45 LS that is the subject of this 510(k) shares the same mechanical parts, electronics, and software as the Vivo 45 LS cleared in K193586, except for the differences described below.
Auto EPAP: The device software has been modified to provide an option for auto-titration of the Expiratory Positive Airway Pressure (EPAP) in pressure ventilation modes. Auto EPAP is indicated for adult patients during non-invasive ventilation with a passive leakage circuit. The Auto EPAP function adjusts the EPAP level within a clinician-prescribed range in response to detected changes in upper-airway resistance to maintain airway patency. The Auto EPAP feature is limited to the PSV+TgV+AE mode.
Flow Trigger: A flow-based inspiratory trigger option has been added. When passive leakage circuits are used, the user can select either the existing type of trigger available in the predicate device (tradename "eSync"), or the flow trigger. With the flow trigger selected, the user chooses the patient flow level in liters per minute to trigger a breath.
Both the Vivo 45 LS and the Trilogy Evo limit use of the function to non-invasive ventilation with passive leakage circuits in pressure ventilation modes only. Auto EPAP in the Trilogy Evo is intended for patients ≥ 10 kg, and in the Vivo 45 LS for Adult patient only (i.e., within the range of the Trilogy Evo). Both devices make the Auto EPAP function available in equivalent pressure ventilation modes as discussed above. The Auto EPAP functions of both devices monitor for changes in the estimated expiratory resistance of the upper airway and titrate the EPAP with the aim of finding the knee of the EPAP versus upper airway resistance curve (i.e., the EPAP above which there is no added benefit in terms of airway patency and below which the upper airway resistance progressively increases). Both devices provide the same set of Auto EPAP related settings including EPAP Min/Max, PS Min/Max, and Pressure Limit ("Max Pressure") to allow the prescribing clinician to constrain the EPAP and inspiratory pressure to remain within an acceptable range for the given patient. All of the alarms provided by the Trilogy Evo in AVAPS-AE mode are also provided by the Vivo 45 LS with Auto EPAP enabled.
The flow trigger of the subject device is equivalent to the flow trigger of the Trilogy Evo in terms of design (triggering when the estimated patient flow exceeds a user-specified threshold) and the user-selectable threshold ranges available. The flow triggers of both devices were utilized in comparative testing of the Auto EPAP function, which further supports equivalence.
The Breas Vivo 45 LS has the same intended use and similar technological characteristics to the predicate devices.
Performance Data
The Vivo 45 LS was subjected to performance testing related to the software modifications which verified conformance with all requirements specifications and applicable standards, and
Page 8
which included comparative testing with the Vivo 45 LS predicate device which supported substantial equivalence. The Auto EPAP feature in PSV+TgV+AE mode uses an expiratory time constant measurement, or absence of flow measurement, as the input parameter to the Auto EPAP adjustment algorithm. The Auto EPAP feature in the PSV+TgV+AE mode was validated with a combination of real world patient data and simulated lung model bench testing. Real world patient data included a retrospective review of device data from 30 patients for safety analysis, and data from 30 patients regarding efficacy.
| Performance Testing |
|---|
| Testing of flow trigger was performed which showed that the trigger performed as intended, detecting patient efforts as expected according to the user sensitivity setting across the intended range. Further verification testing of the flow trigger function demonstrated that it met all specifications. |
| Testing of the Vivo 45 LS was performed to confirm accuracy of controls and monitored values. The testing confirmed that the Vivo 45 LS meets its accuracy specifications. |
| Alarms testing of the Vivo 45 LS was performed which confirmed proper operation of physiologic and technical alarms. |
| Cybersecurity testing confirmed conformance with all cybersecurity specifications. |
| Software verification and validation were performed at the unit, integration, and system level according to plans and protocols with predetermined pass/fail criteria. All tests passed. |
The testing described confirms that the Vivo 45 LS meets all requirements specifications and complies with the relevant standards, and is therefore substantially equivalent to the predicate devices.
Conclusion:
The Vivo 45 LS is substantially equivalent to the predicate devices, as the devices share a common intended use and technological characteristics as demonstrated through performance testing.
