### Intended Use:
To provide continuous or intermittent ventilatory support for the care of individuals who require mechanical ventilation.
#### Indications for Use:
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 modes are for adult patients only.
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.
### Device Description:
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:
The Vivo 45 LS is a modification to the Vivo 60 ventilator cleared in K160481. The Vivo 45 LS is physically smaller than the Vivo 60 and includes some added features. The Vivo 45 LS user interface design is the same as the Vivo 60, with the same layout of displays, data and menus on the LCD screen, and the same layout of physical buttons for the user to take actions such as starting and stopping treatment, navigating the screen, and selecting parameters. The Vivo 45 LS software originated from the Vivo 60 software, and as such shares the same algorithms and remains very similar. The 45 LS electronics design also originated from the Vivo 60 and remains very similar. The blower inside the Vivo 45 LS is a slightly smaller version of the blower inside the Vivo 60 but has the same mechanical and electrical design.
{5}------------------------------------------------
The Breas Vivo 45 LS has the same intended use and similar technological characteristics to the two predicate devices; the primary predicate device is the Vivo 45 LS (cleared in K160481) and the secondary predicate is the Respironics Trilogy Evo (cleared in K181166). Breas Medical believes that the Vivo 45 LS described in this notification and for use under the conditions of the proposed labeling is substantially equivalent to legally marketed predicate devices that are also Class II medical devices.
The intended use of the Vivo 45 LS it to provide continuous or intermittent ventilatory support for the care of individuals who require mechanical ventilation which is the same as the intended use for the Vivo 60. Although the Vivo 45 LS is a modification of the Vivo 60 and has many shared features, there are also technological characteristics which are different. Both the Vivo 45 LS and the Vivo 60 are software controlled devices that receive ambient air through an inlet, utilize a turbine to generate the required pressures and flows, and pass the air to the patient via an outlet. Both devices provide a bleed-in connection for a low pressure, low flow supplemental oxygen supply. The majority of the ventilation modes are identical between the Vivo 45 LS and the Vivo 60 with one additional mode, mouthpiece ventilation, provided in the Vivo 45 LS. Additionally the ventilation parameter settings are largely unchanged as are the alarm settings. The accuracy of controls and accuracy of monitored values are the same between the devices. The user interfaces, power management features, environmental characteristics and data connectivity are all substantially equivalent between the devices. The optional accessories are either cleared in another 510(k) or substantially equivalent to those cleared in the predicate devices.
The Vivo 45 LS includes mouthpiece ventilation which is not included in the Vivo 60 but is a feature of the secondary predicate device, the Trilogy Evo. Both devices have intended use which is to provide continuous or intermittent ventilatory support for the care of individuals who require mechanical ventilation. The Vivo 45 LS and the Trilogy Evo have the same technological characteristics in regards to mouthpiece ventilation with minor differences in the exact performance specifications.
The Vivo 45 LS is substantially equivalent to the combination of the Vivo 60 and Trilogy Evo both of which are legally marketed predicate devices.
## Performance Testing:
The Vivo 45 LS was subjected to performance testing which verified conformance with all requirements specifications and applicable standards, and which included comparative testing with the Vivo 60 predicate device which supported substantial equivalence. Additional testing was performed to support the substantial equivalence to the secondary predicate device, the Trilogy Evo for the mouthpiece ventilation.

Cleaning validation was performed to ensure no physical or performance degradation occurred.
RFID immunity testing was performed to the Association for Automatic Identification and Mobility (AIM) standard 7351731includng 134 kHz and 13.56 MHz RFID sources. The Vivo 45 LS passed all tests.
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.
Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
