## Predicate Device
Primary Predicate: EasyOne Pro Respiratory Analysis System, model EasyOne Pro K091428 Secondary Predicate:
EasyOne Pro Respiratory Analysis System, model EasyOne Pro LAB K120635
## Device Description
The EasyOne Pro Respiratory Analysis System consists of two different device models: EasyOne Pro and EasyOne Pro LAB.
The EasyOne Pro Respiratory Analysis System devices are pulmonary function testing devices. Both EasyOne Pro Respiratory Analysis System device models provide Spirometry and Single Breath CO Diffusion (DLCO) tests including Lung Volume Parameters. The device model EasyOne Pro LAB additionally provides the Nitrogen Multiple Breath Washout (MBW) method. The
{4}------------------------------------------------
EasyOne Pro Respiratory Analysis System devices meet the ATS recommendations for accuracy and precision for Spirometry, DLCO and MBW tests.
The EasyOne Pro Respiratory Analysis System devices can be used as a stand-alone system and can be connected to a network.
The EasyOne Pro Respiratory Analysis System devices use the following sensors: An ultrasonic flow sensor to measure flow velocity, volume and molar mass of the gases that the patient inhales and exhales; a molar mass sensor which determines the helium content of the respired air for the DLCO test and the nitrogen concentration for the multiple-breath washout (MBW) test; a CO sensor (EasyOne Pro) or a combined CO/CO₂ sensor (EasyOne Pro LAB) to determine CO and CO2 content in breathing gas; a temperature and humidity sensor to collect environmental data.
The EasyOne Pro Respiratory Analysis System devices are used in combination with test gases (DLCO gas for DLCO tests and O2 for MBW tests).
The EasyOne Pro Respiratory Analysis System devices are used in combination with the singlepatient use breathing tube ndd Spirette. For DLCO and MBW tests, the additional single-patient use accessories, the ndd DLCO or FRC Barriettes, are used.
The single-patient use accessories prevent cross-contamination between patients. The Spirette prevents the passage of microorganisms into the inside of the flow sensor; the Barriettes prevent the passage of microorganisms into gas supply tubing.
## Intended Use:
EasyOne Pro/LAB is designed for conducting lung function measurements in general or specialist practices or in hospitals.
EasyOne Pro/LAB can also be used in clinical settings in occupational medicine for performing lung function screenings or measurements.
EasyOne Pro/LAB is used to conduct lung function measurements on adults and children starting at age 4, except measurements of diffusing capacity of the lung based on CO (DLCO), which can be performed on adults and children starting at age 6.
## Comparison of Technological Characteristics:
The modified device models of the EasyOne Pro Respiratory Analysis System have the same technological characteristics with regards to Spirometry, DLCO and MBW testing as the predicate devices.

Side-by-side comparison of technological characteristics
{5}------------------------------------------------
{6}------------------------------------------------
{7}------------------------------------------------
{8}------------------------------------------------
The same single-patient use accessories – Spirette, DLCO Barriette and FRC Barriette – are used with the modified devices than with the predicate devices. The same materials in the patient gas path are used with the modified devices and the predicate devices.
Differences between the modified and the predicate EasyOne Pro Respiratory Analysis System devices:
- • The modified devices differ in appearance from the predicate devices in that they have a different color scheme of the device housing, a different on/off button and a different design of the software user interface.
- A capacitive touch screen is used for the modified devices in comparison to the resistive touch screen used for the predicate devices.
- A different PC-board but providing the same functionalities is used for the modified devices.
- In the modified devices, a metal box around the CO or CO/CO₂ sensor provides improved EMC protection.
- . A power supply of higher efficiency but identical environmental specifications is used for the modified devices.
- An internal USB stick instead of a CF card for internal back-up data storage is used for the modified devices.
- . DISS gas hose connectors are used in the modified devices instead of the Quick Connectors used in the predicate devices.
- • The board used for data acquisition is modified compared to the predicate device, but keeping the same functions.
- • The outer geometry of the MMss sensor is modified compared to the predicate devices, but without modifying the operating principle and functionality of the sensor.
- . For the modified EasyOne Pro LAB device model, a modified combined CO/CO2 sensor is used; the modified combined CO/CO₂ sensor contains an additional reference path but has the same performance specifications as the combined CO/CO2 sensor used in the predicate device.
- The modified devices use Windows 8 instead of Windows XP embedded operating system and SQLite/Microsoft SQL server as database technology instead of Microsoft Access.
- . For the modified devices, some of the labelled specifications were updated to reflect the technical capabilities. No changes were made to the components the specifications relate to.
Design verification and validation demonstrated that the performance of the modified EasyOne Pro Respiratory Analysis System is the same as for the predicate EasyOne Pro Respiratory Analysis System. The modified as well as the predicate EasyOne Pro Respiratory Analysis System meet the ATS recommendations for accuracy and precision for spirometry, DLCO and MBW tests. The modified EasyOne Pro Respiratory Analysis System is therefore substantially equivalent to the predicate EasyOne Pro Respiratory Analysis System.
## Summary of Testing:
Simulated Spirometry, DLCO and MBW testing, as well as testing with humans, confirmed that the modified EasyOne Pro Respiratory Analysis System devices meet the recommendations for accuracy and precision for Spirometry, DLCO and MBW tests of the American Thoracic Society (ATS).
The modified devices were tested to demonstrate conformance with the requirements for medical electrical equipment basic safety and essential performance of standards IEC 60601-1 and IEC 60601-1-2.
{9}------------------------------------------------
Software verification and validation in accordance with IEC 62304 confirmed that the modified EasyOne Pro Respiratory Analysis System meets the specified criteria.
Biocompatibility was evaluated in accordance with ISO 10993-1: Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing within a Risk Management Process.
#### Conclusion:
Based on the above, ndd Medical Technologies concluded that the modified EasyOne Pro Respiratory Analysis System is substantially equivalent to the legally marketed predicate devices and is as safe and as effective for their intended use.
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.
