### Device Description:
The Alar / Nasal SpO2 Sensor is a disposable, single patient use Pulse Oximetry sensor designed to attach to the patient's nasal alar region - the fleshy region at the side of the nose. Skin contact and adhesive free sensor retention is via soft silicone rubber cushions encapsulating the optical components. The Alar / Nasal SpO2 Sensor with its associated patient cable, terminates in a DB-9 connector compatible with monitors employing Nellcor SpO2 technology.
The sensor utilizes red and IR LED light sources of 660 nm and 880 nm respectively along with a silicon photodiode detector to detect changes in oxygen saturation in the blood. Since oxygen saturated blood absorbs different amounts of light at each wavelength (red and infrared) as compared with unsaturated blood, the amount of light absorbed at each wavelength by the blood in each pulse can be used to calculate oxygen saturation.
### Indications for Use:
The Assurance™ Nasal / Alar SpO2 Sensor is indicated for single patient use for continuously noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO-) and pulse rate from the nasal ala of adult and pediatric patients (weighing > 30kg), who are well or poorly perfused. The sensor can be used in a variety of healthcare environments where compatible pulse oximetry monitors are indicated for use, under professional supervision.

## Substantial Equivalence Discussion
The table above compares the key features of the proposed Assurance™ Alar / Nasal SpO2 Sensor as compared to the predicate Xhale Assurance™ Alar SpO2 Sensor (K122996) and the predicate Nellcor OxiMax Sensor (K060576).
## Discussion of Differences:
The differences between the proposed Alar / Nasal SpO- Sensor and the predicate Alar Sensor (K122996):
- · The Alar / Nasal SpO2 Sensor has 1 (one) wire connecting the sensor to the DB-9 connector.
- The predicate device had a separate AB-N Adaptor Cable that was necessary to o connect to a DB-9 port.
- The proposed Alar / Nasal SpO2 Sensor removed the need for the additional o adaptor by direct connection of the sensor assembly to the cable with a DB-9 connector.
- The proposed Alar / Nasal SpO2 Sensor has a PCB with embedded software that is ● directly connected to the DB-9 connector.
- This allows the sensor to communicate with the compatible pulse oximetry o equipment and display the SpO2 and heart rate data on the screen.
- Pulse Rate Accuracy - Testing was performed for the accuracy of pulse rate over the range from 30-240 bpm using a SpO2 simulator the results were identical pulse rate accuracy within + 3 bpm over the tested range. We tested 30-240 bpm when the predicate Alar (K122996) was tested at 30-250 bpm. This test method difference is not significant as long as it is disclosed in the labeling and is equivalent to the predicate K122996 - Xhale Assurance™ Alar SpO2 sensor.
Discussion - These differences can be viewed as substantially equivalent and do not raise any new safety or effectiveness concerns when compared to the predicate K122996 - Xhale Assurance™ Alar SpO2 sensor.
In summary one can conclude that substantial equivalence is met based upon the following:
Indications for Use – The indications for use are identical for the proposed device when compared to the predicate - K122996 - Xhale Assurance™ Alar SpO2 sensor. Discussion - Each device is indicated for use as a pulse oximeter sensor.
Technology and construction - The technology is identical to the predicate K122996 - Xhale Assurance™ Alar SpO2 sensor. The basic design, fabrication, constructions and materials are identical to the predicate K122996 - Xhale Assurance™ Alar SpO2 sensor. Discussion - The basic design, fabrication, constructions and materials are identical to the predicate K122996 - Xhale Assurance™ Alar SpO2 sensor.
Patient Population - The patient population is identical to the predicate K122996 - Xhale Assurance™ Alar SpO2 sensor.
Discussion - The patient population is identical - predicate and adults > 30kg.
{7}------------------------------------------------

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.
