## NAME OF LEGALLY MARKETED DEVICE FOR WHICH A CLAIM OF SUBSTANTIAL EQUIVALENCE IS MADE as required by 807.92(a)(3)
The Datex-Ohmeda S/5TM FM with L- FICU04 and L- FICU04A software is substantially equivalent to the predicate Datex-Ohmeda S/5™ Compact Critical Care Monitor with L-CICU02 and L-CICU02A software (K022740). The N-F(C)(REC) Extension module used with the FM Monitor allows measuring CO2 (module versions N-FC and N-FCREC) and printing on a recorder chart (module versions N-FREC and N-FCREC). The CO2 measurement of the N-FC(REC) is based on the CO2 measurement of the predicate M-miniC module (K023454). The recorder option is based on the predicate M-REC module, originally cleared in the Datex AS/3 AM Monitor (K933285) and the Datex AS/3 Compact Monitor (K933156) submissions.
#### DEVICE DESCRIPTION as required by 807.92(a)(4)
The S/5™ FM Monitor with L-FICU04(A) software is a patient monitor, which measures and displays patient physiological parameters in hospital environments. The S/5™ FM uses two types of plug-in measurement modules: Extension module N-F(C)(REC) with CO2 or Recorder option, or both, and Patient side Module E-PSM(P), that measures ECG, impedance respiration , invasive and non-invasive blood pressures, pulse oximetry and temperature. The E-PSM(P) is the subject of a separate 510(k). The miniC unit of the N-FC(REC) Extension module, included in this 510(k) submission, is a side stream gas analyzer. It monitors the Carbon dioxide (CO2) inhaled and exhaled by the patient, by measuring the absorption of CO2 at 4.2-4.3 micrometer using narrow band IR filters. It can also monitor the respiration rate as the frequency of peak (end tidal) CO2 measurements per minute. All concentrations are measured and displayed breath by breath. The MiniC unit of the Extension module is equipped with the mini D-fend water separation system. There are two software options available for the S/5 FM: L-FICU04 and L-FICU04A. The L-FICU04A is equipped with extended arrhythmia analysis capability. Other than arrhythmia analysis capabilities, this software option is identical to the L-FICU04. Commonly, the software is collectively referred to as L-FICU04(A). The E-PSM(P) and N-F(C)(REC) Modules placed in the S/5 FM are automatically recognized by the monitor. Monitoring can begin when patient cables are connected to the module plug-in jacks. The modules perform parameter measurement and minor data processing. The S/5™ FM displays measured parameters in the form of numeric values, waveforms and trends on the screen. Audible and visual alarms are used to indicate patient status. The priority profile of an alarm depends on the parameter. The L-FICU04(A) software performs some module-related tasks like arrhythmia analysis, ST value calculation, heart rate calculation, impedance and respiration rate calculation. All the module communication is also handled in the main software. The S/5™ FM is operated by command board keys. Typically pressing a key results in a pop up menu appearing on the screen. Selections can then be made easily from the menu using a unique ergonomically designed pointing device on the keyboard called a ComWheel™. In addition of the standard command board there is an optional type of keyboard, a hand-held Remote controller (REMCO), which is directly connected to the S/5™ FM via a long cord but provides more flexibility in controlling the monitor while the doctor or nurse is handling other patient care needs. The Recorder is a thermal array printer with which you can print from one to three traces and numerical information with a selectable speed. The S/5™ FM Monitor can be in a stand-alone or networked configuration. If networked, measurement data (parameter-associated numbers, waveforms or trends and patient care documentation) is sent to the network for central viewing of the network, monitor-to-monitor viewing, or for archiving. Software I .- FICU04 and L-FICU04A include support for wireless LAN communication between the monitor and S/5 Central station. The networking can thus be hardwired or wireless.

The S/5™ FM with L-FICU04 and L-FICU04A and N-FCREC Module are intended for multiparameter patient monitoring.
#### Indications for use:
The S/5 FM with L-FICU04 or L-FICU04A software is indicated for monitoring of . hemodynamics (including arrhythmia and ST-segment analysis) and respiratory status of all hospital patients.
Extension module N-FCREC (option N-FCREC or N-FC) is indicated for monitoring CO2 and respiration rate of all hospital patients. CO2 measurements are indicated for patients weighing over 5kg (11lbs).
The S/5 FM Monitor and N-F(C)(REC) Extension Module are 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 Datex-Ohmeda S/5™ FM with L- FICU04 and L- FICU04A software is substantially equivalent to the predicate Datex-Ohmeda S/5™ Compact Critical Care Monitor with L-CICU02 and L-CICU02A software (K022740), as indicated by the similarities discussed below.
The S/5™ FM Monitor is a modular multiparameter patient monitor providing connections to measurement modules, in a similar way as the predicate device. The general construction, indications for use and intended use of the S/5™ FM Monitor are almost the same as for the predicate device (K022740).
The basic model of the monitor is the S/5™ FM with L-FICU04 software. When equipped with extended bedside arrhythmia analysis capability, the monitor is called S/5™ FM with L-FICU04A. The arrhythmia analysis functionality of the S/5TM FM with L-FICU04A is identical to the functionality of the predicate device S/5™ Compact Critical Care Monitor with L-CICU02A software (K022740).
The N-F(C)(REC) Extension module used with the FM Monitor allows measuring CO2 (module versions N-FC and N-FCREC) and printing on a recorder chart (module versions N-FREC and N-FCREC). The CO2 measurement of the N-FC(REC) is based on the CO2 measurement of the predicate M-miniC module (K023454). The recorder option is based on the predicate M-REC module, originally cleared in the Datex AS/3 AM Monitor (K933285) and the Datex AS/3 Compact Monitor (K933156) submissions.
The S/5™ FM Monitor and its predicate device both have the same basic user interface and alarms. They are manufactured using the same processes, and have the same safety and effectiveness, as indicated by the thorough and successful testing of the FM Monitor, documented in this submission.
Based on the above and a detailed analysis in other documentation included in this 510(k) notification and attachments, it is evident that the main features and indications for use of the S/5™ FM Monitor with I - L-FICU04 and L- L-FICU04A software are substantially equivalent in safety and effectiveness compared to the predicate.
{3}------------------------------------------------

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.
