Indications for Use
The Silent Night V is indicated for use in the diagnostic evaluation of adults with possible sleep-disordered breathing. The Silent Night V can score obstructive apneas, which includes mixed apneas.
Device Story
Silent Night V is a portable, line-powered ventilatory effort recorder for home diagnostic evaluation of sleep-disordered breathing. Device consists of a bedside unit connected to patient-worn sensors via cable. Inputs include arterial oxygen saturation (SpO2), pulse rate, respiratory effort signal, and ambient room noise. Device stores sleep data, including apnea/hypopnea events, saturation levels, and pulse rate, for up to 8 hours. Software retrieves, scores, displays, and prints data for physician review. Physician uses output to evaluate sleep-disordered breathing and apnea. Provides cost-effective home-based diagnostic alternative to laboratory polysomnography.
Clinical Evidence
Clinical evaluation compared Silent Night V to standard polysomnography (PSG) in a laboratory setting. Study measured apneas, hypopneas, and Respiratory Disturbance Index (RDI). Results showed a 97.7% correlation coefficient for RDI scores between devices. Apnea detection sensitivity was 83.2% (3.5 false positives/hour); overall event sensitivity (apneas and hypopneas) was 90.7% (3.8 false positives/hour). At an RDI cut-off of 15, the device achieved 95% sensitivity and 91% specificity compared to PSG.
Technological Characteristics
Portable, line-powered bedside unit. Sensors connect via cable to patient module. Complies with IEC 60601-1 and IEC 801-X for mechanical/environmental safety. Data storage capacity 512 Kbytes. Software-based scoring of respiratory events.
Indications for Use
Indicated for diagnostic evaluation of adults with possible sleep-disordered breathing, including scoring of obstructive and mixed apneas.

### Performance Data:
Engineering data - Silent Night V was evaluated according to appropriate stadiance IDCCALL LLCC mechanical and environmentul wsting. The device is in compliance with IBC 60601-1 and IEC 801-X (for mechanical and environmental stresses) standards.
Clinical data - Silent Night V was evaluated in the clinical setting. Patients underwent a sleep laboratory evaluation with a standard polysomnograph. Silent Night V was used concomitantly for a side-by-side comparison. The number of apneas, bypopneas and the resulting Respiratory Disturbance Index (RDI) companson. The number of appeared with the data gathered simultaneously by the standard polysomnograph. The dala were compared on an event-by-event basis. The RDI scares were determined and compared with the RDI score from the PSG using the Peurson r. The correlation coefficient between the PSG and the Silent Night V was 97.7%. Using the total number of apneas as the basis for calculation, the sensitivity between the two devices for apnea detection was 83.2% and the number of false positive wents per hour was 3.5 (# of false positive apness per hour). Using the total number of events (appreas and hypopuleas) as the basis for calculation, the overall schsitivity was 90.7% and the number of false positive events per hour was 3.8.
The definition for RDI is the 10tal number of apneas and hypopneas, divided by the study duration (in hours). For RDI, using the overall number of patients as the hasis of calculation, and a cut-off of RDI=15, the Silent Night V achieved a sensitivity of 95% and a specificity of 91% when compared to the 1786.
The results of the clinical study demonstrated the performance of the Silent Night V in detecting disordered breathing events, which can be indicative of sleep apnea. In view of the noninvasive, userfricadly design and simple operational features of the Silent Night V offers potential benefit as a cost effective home use device for the evaluation of patients with possible sleep disorders.
Conclusion: The information and data, provided in this 510(k) notification established that the Silem Night V is substantially equivalent to legally marketed predicate devices.

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.
