It is intended for spot checking of adult and pediatric patients on digits between 0.3 - 1.0 inch (0.8 - 2.5 cm) thick.
# Device Description: Model 3230 Bluetooth® Smart Pulse oximeter is a small, lightweight, portable, digit pulse oximeter that displays numerical values for functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate by measuring the absorption of red and infrared (IR) light passing through perfused tissue. Changes in the absorption caused by the pulsation of blood in the vascular bed are used to determine oxygen saturation and pulse rate. Light emitting diodes (LEDs) are contained within the device along with the photo detector, which is on the opposite side of the probe from the LEDs. The SpO2 and pulse rate are displayed on the LCD display contained within the device. A color LCD provides a visual indication of the pulse signal, while blinking at the corresponding pulse rate. The display will indicate if poor pulse quality that may affect the readings. All associated electronics and the microcontrollers are within the sensor, which is activated by placing on a patient's digit. This simple operation activates the internal circuitry automatically upon application. The device is intended for spot-checking adult and pediatric patients who are well or poorly perfused.

the co-oximeter samples measured over the SpO2 range of 70-100%. Accuracy data was calculated using the root-mean-squared (Arms value) for all subjects, per ISO 80601-2-61 and ISO 9919, Standard Specification for Pulse Oximeters for Accuracy in a non-motion environment demonstrated a specified accuracy of ±2%. There were no reported adverse effects during these investigations.
The purpose of this study was to verify SpO? performance accuracy of the Nonin Medical pulse oximeter system on the finger and thumb in stationary (non-motion) conditions over the range of 70 to 100 percent SaO2. Accuracy of device on the toes was also verified. These aims were achieved by comparing SpO2 measurements with those of arterial blood samples assessed by CO-oximetry. The study was designed in accordance with ISO 80601-2-61 and ISO 9919. The goal, in its entirety, was to show the SpO2 accuracy performance for the devices. It was expected that the Accuracy Root Mean Square (Ams) performance of the above pulse oximetry systems will meet a specification of ±3% for the range of 70 - 100% SaOz.
Methods: Subjects were connected to a breathing circuit, in which the gas flow delivery was adjusted for subject comfort. This gas circuit provided a gas mixture of medical grade oxygen and nitrogen. The program was run in manual mode, in which the gas mixture was changed by the controller. The program was used to induce hypoxia in a stair-stepped manner which allowed each subject to settle at his or her SpOzlevel (e.g. plateau). At each plateau, arterial blood sampling was performed. After drawing a waste sample to clear the arterial line, an arterial sample was drawn. The beginning and end of each draw was noted on the data collection system. This series of waste draw, and arterial draws was repeated multiple times for each plateau. At the end of each plateau, the arterial line was flushed with sterile saline. Subsequently, the program was adjusted to allow the subject to reach a new level of SpOz and the process was repeated. Samples were run on four (4) CO-oximeters. The SpO2 values at each draw were paired with the average of the two OSM (Radiometer) CO-oximeters.
This study enrolled subjects who were provided IRB-approved informed consent as documented on an informed consent form. Subjects needed to be healthy, non-smoking, competent adults, between eighteen and forty-five (18-45) years of age. Good health was evidenced by satisfactory completion of a health assessment form.
Conclusions: The oximeter in a non-motion environment demonstrated a specified accuracy of ±2% over the specified range. The oximeter, in a non-motion environment demonstrated a specified accuracy of ±3% on the toe.

USABILITY: The testing performed for this Usability / Human Factors Study was to get real user feedback from both naïve and experienced pulse oximeter users.
The primary objective of this study was to collect data to demonstrate the usability of the Model 3230 Oximeter in the intended patient population for simulated home use and identify any potential impediments to use. The usability components tested in this study included effectiveness, symbol comprehension and operator satisfaction. Effectiveness and symbol comprehension were the primary objectives. Operator satisfaction, time to first reading, and time to shut off were secondary objectives.
Effectiveness was assessed by determining the rates of proper placement, proper device assembly, and proper device disassembly.
Methods: Prior to using the device, users were given a Quick Start Guide and Instructions for Use (IFU) that included instructions and diagrams for placement and use of the device. The user was then instructed to perform specific tasks with the device. These tasks simulated home use and include assembly, use, and disassembly of the device After use, the user was asked to complete a questionnaire regarding the various aspects of using the Model 3230 Oximeter, symbol comprehension, and to provide feedback to improve device use or instructions for use.
Usability validation was conducted with 27 subjects. Subjects needed to be healthy competent adults. There were no reported adverse effects during these investigations.
Conclusion: The Model 3230 has been found to be safe and effective for the intended users, uses and use environments.
Conclusion:
Nonin's Model 3230 is substantially equivalent to the On;x Vantage 9590 cleared by the FDA under K112843 on 4/19/2012, and the Model 9560 Onyx II Finger Pulse Oximeter and cleared by the FDA under K081285 on 6/5/2008 both manufactured by Nonin Medical, Inc.

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.
