These devices are for prescription use only.
Device Story
OxiMAX Pulse Oximetry System provides continuous, non-invasive monitoring of SpO2 and pulse rate. System inputs include optical signals from OxiMAX sensors (red/infrared LEDs and photodiode) placed on patient tissue. Sensors contain memory chips storing calibration and sensor-specific data. The N-595 oximeter processes these signals using digital signal processing to calculate SpO2, pulse rate, and pulse amplitude. Output is displayed as digital values and plethysmographic waveforms on the N-595 unit. Used in hospitals, transport, and home environments by clinicians or patients. Features include SatSeconds alarm management, motion-artifact filtering, and in-sensor data storage for patient history portability. Device aids clinical decision-making by providing real-time oxygenation status and trend data, facilitating timely intervention for hypoxemia.
Clinical Evidence
Clinical and non-clinical tests were performed in accordance with 21 CFR Parts 812, 50, and 56. The system was validated against predicate devices to ensure performance equivalence in monitoring SpO2 and pulse rate under various conditions, including motion and low perfusion. No specific numerical clinical trial results (e.g., sensitivity/specificity) are provided in the summary document.
Technological Characteristics
System uses red and infrared LED light sources and a photodiode detector to measure tissue optical properties. Includes OxiMAX sensors with integrated memory chips for data storage. Features Advanced Digital Signal Processing for motion/low perfusion, SatSeconds alarm management, and serial connectivity (EIA-232/RS-422). Powered by AC or internal 6V rechargeable lead-acid battery. Software includes motion-filtering and alarm management algorithms.

#### 1. Device Description
The OxiMAX Pulse Oximetry System is designed for continuous, non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate by use of one of a range of compatible Nellcor OxiMAX oxygen transducers (sensors). The N-595 Pulse Oximeter displays digital values of SpO2 and Pulse Rate. Pulse Amplitude is displayed by means of a "blip bar" presentation or plethysmographic waveform. The N-595 can be powered by an internal power supply operating on AC
510(k) Summary - Page 1
{1}------------------------------------------------
from a standard electrical utility receptacle (manually switchable from 115V to 230V) or alternatively by an integral sealed 6V rechargeable lead-acid battery. TheOxiMAX Pulse Oximetry System is intended for prescription use with adult, pediatric and neonatal patients in hospitals, hospital-type facilities, intra-hospital transport, and home environments.
Audible and visual alarms for high/low saturation, pulse rate and pulse search are provided. The N-595 Pulse Oximeter also includes adjustable alarm silence duration and other configurable power-on settings. The N-595 provides an audible low battery warning to alert the user of impending loss of power and consequent loss of monitoring capability. The N-595 Pulse Oximeter has visual indicators for pulse search, motion, power mode (i.e., battery or AC), alarm silence and alarm features. There is also a serial port (EIA-232 and RS-422 interface) that provides ASCII output of real-time data. Via the serial port, the N-595 interfaces with selected multiparameter monitors.
The Nellcor pulse oximetry cable, Model DOC-10, links individual OxiMAX sensors to the N-595 Pulse Oximeter. The N-595 and DOC-10 are intended for use only with the OxiMAX family of sensors. These OxiMAX sensors each contain a memory chip carrying information about the sensor which the oximeter needs for correct operation, including in-sensor data. Advanced Signal Evaluation, lot code and data set revision, and sensor model. These OxiMAX sensors include the following models: OxiMAX MAX-A, MAX-AL, MAX-P, MAX-I, MAX-N, MAX-R, MAX-FAST, OxiCliq-A, OxiClig-I, OxiCliq-N, DS-100A, D-YS, D-YSE, D-YSPD, OXI-A/N, and OXI-P/I.
#### II. Intended Use
The OxiMAX Pulse Oximetry System is indicated for the continuous non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate. It is intended for use with neonatal, pediatric, and adult patients during both no motion and motion conditions and for patients who are either well or poorly perfused, in hospitals, hospital-type facilities, intra-hospital transport, and home environments. These devices are for prescription use only.
### III. Technological Characteristics
The OxiMAX Pulse Oximetry System measures functional oxygen saturation noninvasively via a light signal interacting with tissue, by utilizing the time-varying changes in tissue optical properties that occur with pulsatile blood flow. Red and infrared lightemitting diodes (LEDs) are utilized as light sources. A photodiode acting as a photodetector senses the signal strengths of the two wavelengths of light, which vary with the amount of light transmitted through the tissue. The N-595 Pulse Oximeter receives this electrical information from the sensor and processes the information by use of an algorithm to provide real time values of SpO2, pulse rate and pulse amplitude.
OxiMAX technology encompasses:
- OxiMAX Advanced Digital Signal Processing for reading through motion artifact . and low perfusion
- . Advanced Signal Evaluation providing the user information on sensor placement
- SatSeconds Alarm Management .
{2}------------------------------------------------
- . OxiMAX Sensor Technology, including in-sensor data, allows the N-595 to write data to and read data from OxiMAX adhesive sensors
- MAX-FAST Adhesive Forehead Reflectance Sensor .
The N-595 uses similar SpO2 and Pulse Rate software algorithm, motion-filtering software, and SatSeconds alarm management software as the legally marketed predicate device, N-395, that was cleared under 510(k)s #K991823 and #K993637.
Nellcor brand sensors containing OxiMAX technology are compatible with the N-595, other Nellcor oximeters and instruments containing Nellcor oximetry, or with instruments licensed to use Nellcor sensors (Nellcor-compatible instruments). OxiMAX Sensor Technology, including in-sensor data, allows the N-595 to write data to and read data from OxiMAX adhesive sensors allowing patient history, namely SpO2 and pulse rate alarm events, to travel with the patient, and enabling quick patient assessment upon transfer to a new point of care. The N-595 provides on-screen viewing of in-sensor patient data including SpO2 and pulse rate trend of events.
## IV. Tests Performed to Support Determination of Substantial Equivalence
Clinical and non-clinical tests were performed to support the determination of substantial equivalence. Clinical studies were conducted following regulations under Title 21 of the Code of Federal Regulations (21 CFR), Part 812 - Investigational Device Exemptions, Part 50 - Protection of Human Subjects and Part 56 - Institutional Review Boards.
### V. Conclusions
The technological characteristics of the OxiMAX Pulse Oximetry System and the results of non-clinical and clinical tests do not raise new questions of safety or effectiveness when compared to the legally marketed predicate devices.

(Optional Format 3-10-98)
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.
