#### Manufacturers / Designers of Oxygen & Nitrogen Generating Equipment
Requirements are based on the deployment oxygen system- medium (DOGS-M), operational requirements documents that have been issued by the United States Air Force and the United States Army. These two services are preparing a joint requirement document. This system is based on the Pressure Swing Absorption principle and uses a molecular sieve to separate gasses from the filtered ambient air. The oxygen is stored and delivered to the patient(s) through the oxygen boost and distribution system.
The POGS 65/130 is a system that generates USP 93% oxygen at a flow rate of up to 65 LPM at a pressure of 50-60 PSI. Included with the generator are medical-grade oxygen hose for both low and high pressure, spare parts and tools that are required, but may be not be easily accessible to the user. The POGS 65/130 is compatible with commercial oxygen consuming equipment and accessories, including D. E, H, K, and M cylinder filling accessories, ventilators, nasal cannulas, Draeger Narkomed Anesthesia machines and Impact Univent/Eagle 754/754M Ventilators. It also connects with the high pressure Hospital Oxygen Backup System and the low-pressure Patient Oxygen Distribution System.
A complete POGS 65/130 system consists of two (2) feed air compressors, two (2) oxygen generators, one (1) boost and distribution center, and one (1) oxygen back-up system. Each feed air compressor and oxygen generator pair is designed to provide up to 65 LPM independently or can operate in parallel to achieve up to 130 LPM to provide the user flexibility in the deployment of their resources. The approach is modular and enables the user to add or subtract systems to meet the requirements of the situation. Each POGS 65 pair responds to the oxygen demand that is being used and when operated in parallel, will load share between the pair.
The boost and distribution system receives the oxygen from up to two oxygen generators. The boost and distribution system can feed the oxygen to 1) the hospital distribution system, 2) fill the back-up system, 3) fill cylinders or 4) fill the hospital back-up system depending upon the requirements of the situation. To ensure patient care, the hospital distribution system has priority over all other options. One or more type of cylinder or back-up system may be filled in conjunction with supplying the hospital distribution system. The System includes the capability to evacuate high pressure oxygen cylinders to 25 inches Hg vacuum prior to filling.
#### Indications for Use:
The POGS 65/130 is intended to generate and deliver USP 93% supplemental oxygen. This device is intended to be used only by trained personnel in disaster relief and emergency preparedness situations, military settings or where bottled oxygen is not readily available.
#### Difference with Predicate Device:
The POGS 65/130 has included several improvements identified through the operation of the POGS 33C by the military around the world. To roughly double the oxygen output of the system in the same footprint, a new molecular sieve material, MDX made by UOP was used in place of the Oxysieve 5 made by UOP used in the POGS 33C. An input and exhaust valve block has replaced individual valves. The

### Manufacturers / Designers of Oxygen & Nitrogen Generating Equipment
valve block is designed by the same company, MAC, that produces the individual valves, thus we are confident of the lifetime, materials and quality of the components. The system control has been upgraded from a mechanical timer to a PLC. We utilize PLC's throughout the rest of our product line and the manufacturer, Allen-Bradley, is a well known manufacturer of PLC's. The functionality improvement is mainly in the areas of maintenance and troubleshooting and the ease of operation is improved as even those with limited experience with the system can quickly place it into operation and ensure continuous oxygen generation. The POGS 65/130 is not required to produce medical air, therefore there are no provisions for dew point or CO monitoring of the air.
#### Improvements from Previously Cleared Device:
Several improvements have been made to the predicate device. Improvements to the feed air compression packaging, increased oxygen production, enhanced user interface, and improved operator manuals are provided with the new device.
#### Non-Clinical Performance:
Performance Standard ASTM F-1464-93 was used.
Non-clinical bench testing conducted by On-Site Gas Systems, Inc. is sufficient in establishing substantial equivalence on the POGS 33C to the predicate device on which substantial equivalence is claimed, including oxygen purity evaluations.

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.
