The M-miniC is used in the Datex-Ohmeda S/5 modular family which consists of four different types of monitors: Anesthesia Monitor, Compact Anesthesia Monitor, Critical Care Monitor and Compact Critical Care Monitor. An monitor consists of four basic elements: display, keyboard, Central unit and modules. The display shows up to eight waveforms, real-time data and trends. With keyboard you can control the monitor. The keyboard consists of membrane keys and a comwheel. By pushing a key you can open a menu in which you can move by turning the comwheel.
The M-miniC module consists of miniCO2 infrared measuring sensor for measuring CO2. It is assembled in a Single-width module, which occupies one slot in a Datex-Ohmeda S/5 modular monitor frame. The main accessories include airway gas sampling lines, mini D-fend water traps and airway adapters The module is first plugged into the frame of the monitor. The sampling line is attached to the module connector. The monitor is switched on and the gas sampling line is attached to the airway adapter. The airway adapter is attached between ventilator Y-piece and Heat and moisture exchanger (HME) of the patient's intubation tube. The monitor displays measurements from the M-miniC module in the form of numeric values, curve and trends. The monitor also generates audible and visual alarms for this module and indicates the priorities and sources of alarms.

The Datex-Ohmeda S/5 Single-width airway module, M-miniC and accessories is indicated for monitoring CO2 and respiration rate of all hospital patients. M-miniC is indicated for monitoring patients weighing more than 5kg (11 lbs.). The device is indicated for use by qualified medical personnel only.
# SUMMARY OF TECHNOLOGICAL CHARACTERITICS OF DEVICE COMPARED TO THE PREDICATE DEVICE as required by 807,92(a)(6)
The M-miniC module is substantially equivalent in safety and effectiveness to the predicate M-CAIOVX module (K001814). Both the M-miniC and predicate can be used with the same Datex-Ohmeda modular monitors, S/5 Anesthesia Monitor, S/5 Critical Care Monitor, S/5 Compact Anesthesia monitor and S/5 Compact Critical Care Monitor. The M-miniC is compatible with monitor main software L-ANE02(A), L-CANE02(A), L-ICU02(A) and L-CICU02(A) and newer while the predicate (because it was released previously) is compatible with S-ANE97, S-ARK97 and S-ICU97 monitor main software and newer. The measurement principle of CO2 is the same for both the M-miniC and predicate M-CAIOVX modules. They are side stream gas analyzers. measuring real time concentrations of CO2. They measure absorbtion of CO2 at 4.2-4.3um using narrow band IR filters. The detectors of both sensors are thermopiles. The principal structure of the CO2 sensors is the same; there is an IR source, a thermal insulator, a sample chamber and a detector. The sample chamber and detector are inside an aluminium frame and that frame has a thermal insulator around it. The IR source is constant current controlled.
The main difference is that the M-miniC measures only CO2 while the predicate M-CAIOVX measures additionally N2O and anesthetic agents and therefore the CO2 sensor of the M-miniC is smaller and consumes less power. The predicate M-CAIOVX also has a separate paramagnetic
{2}------------------------------------------------
sensor which measures Oxygen and a separate spirometry unit which monitors patient ventilation and a gas exchange measurement. Both the M-miniC and predicate M-CAIOVX fulfill the same electrical safety standard IEC 601-1. Software in the M-miniC module is based on the same principles as the software of the predicate M-CAIOVX. It is simpler because it has only one gas measurement channel. Its basic functions such as CO2 concentration calculation, pump and IR source control are the same. Its communication protocol with the monitor is also the same. The M-miniC uses the same type of CO2 accessories as the predicate M-CAIOVX. The M-CAIOVX also has many accessories that are not used with the M-miniC because the M-miniC only uses accessories associated with CO2 monitoring. The M-miniC and predicate M-CAIOVX CO2 monitoring accessories are identical except for a new 6 m sampling line and the new mini Dfend water trap. The 6 m sampling line is just a longer version of the 2 m/3 m sampling lines of the predicate and is made from identical materials. The new mini D-fend is a smaller version of the predicate D-fend. The operation principle is the same. The M-miniC module is a single width module while the predicate M-CAIOVX is a double width module. This means the MminiC module only takes up one slot in the monitor frame. The CO2 measurement range of the M-miniC is from 0 to 20 vol% while the CO2 measurement range of the predicate M-CAIOVX is from 0 to 15 yol%. The warm-up time of the M-miniC is 1 min while the warm-up time of the predicate M-CAIOVX is 2 min. The sample flow of the M-miniC is 150 ml/min while the sample flow of the predicate M-CAIOVX is 200 ml/min. The CO2 rise time of the M-miniC is < 300 ms while the CO2 rise time of the predicate M-CAIOVX is < 400 ms. The environmental specification for both modules is the same.
Based on the above analysis and other documentation included in this 510(k) notification and attachments, it is evident that the main features and indications for use of the Datex-Ohmeda S/5 Single-width Airway Module M-miniC and accessories are substantially equivalent to the predicate Datex-Ohmeda Compact Airway Module M-CAiOVX (K001814). The comparison above as well as supporting data and analysis shows that there are no new questions of safety and effectiveness for the Datex-Ohmeda S/5 Single-width Airway Module M-miniC and accessories.

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.
