Device Story
Masimo Rainbow SET Radical 7, Rad 87, and Rad 57t are pulse CO-oximeters using multi-wavelength sensors (620-1270 nm) to measure arterial blood constituents. Sensors collect optical signals from capillary beds (fingertip, hand, foot); photodetectors convert light absorption changes into electronic signals. Masimo Signal Extraction Technology (SET) processes these signals to calculate SpO2, SpCO, SpMet, SpHb, and pulse rate. Devices are used in hospitals, mobile, and home environments by clinicians to assess patient status and guide interventions. Output includes real-time numerical values, pleth waveforms, and trends displayed on the device; Radical 7 and Rad 87 also provide analog/serial outputs for multi-parameter monitors. Benefits include continuous, noninvasive monitoring of hemoglobin species and perfusion status, aiding in early detection of hypoxemia, carbon monoxide poisoning, or methemoglobinemia.
Clinical Evidence
Clinical validation performed on healthy adult volunteers (n=unspecified) and neonatal NICU patients (n=16, age 7-135 days). Accuracy validated against laboratory CO-oximeters for SpO2, SpCO, SpMet, and SpHb. SpO2 accuracy: ±2% (no motion), ±3% (motion). SpHb accuracy: ±1 g/dL (7-17 g/dL range). Pulse rate accuracy: ±3 bpm (no motion), ±5 bpm (motion). Bench testing used for low perfusion and pulse rate validation.
Indicated for continuous noninvasive monitoring of SpO2, pulse rate, SpCO, SpMet, and SpHb in adult, pediatric, and neonatal patients. Applicable for patients with motion or no-motion, and well or poorly perfused states in hospital, mobile, and home settings.

### Principles of Operation
### SpO2 General Description
Pulse oximetry is a continuous and non-invasive method of measuring the level of arterial oxygen saturation in blood. The measurement is taken by placing a sensor on a patient, usually on the fingertip for adults, and the hand or foot for neonates. The sensor connects directly to the pulse oximetry instrument or with a patient cable. The sensor collects signal data from the patient and sends it to the instrument displays the calculated data in tw
Section 5, Page 2 of 9

ways: 1) as a percent value for arterial oxygen saturation (SpO2), and 2) as a pulse rate (PR). Figure 1 shows the general monitoring setup ..
### SpCO, SpMet, and SpHb General Description
Instruments containing Masimo Rainbow SET technology also offer a continuous and non-invasive method of measuring the levels of carboxyhemoglobin concentration (SpCO), methemoglobin concentration (SpMet) and total hemoglobin in blood (SpHb). It relies on the same principles of pulse oximetry to make SpCO, SpMet and SpHb measurements. The measurements are taken by placing a sensor on a patient, usually on the fingertip for adults. The sensor connects directly to the instrument or with a patient cable. The sensor collects signal data from the patient and sends it to the instrument. The instrument displays the calculated data as percentage values for the SpCO and the SpMet and as grams/deciliter (g/dL) for SpHb. Instruments containing Masimo Rainbow SET technology are a combined SpO2, SpMet and SpHb monitor with the same setup as that of a pulse oximeter, shown above, and can display percentage or concentration values for SpCO, SpMet and SpHb as well as SpO2 and pulse rate.
Pulse oximetry is governed by the following principles:
- Oxyhemoglobin (oxygenated blood), deoxyhemoglobin (non-oxygenated blood), carboxyhemoglobin 1. (blood with carbon monoxide content), and methemoglobin (blood with oxidized hemoglobin content) species differ in their absorption of visible and infrared light.
- The amount of arterial blood in tissue changes with your pulse (photoplethysography). Therefore, the ં મં amount of light absorbed by the varying quantities of arterial blood changes as well.
Instruments containing Masimo Rainbow SET technology use a multi-wavelength sensor to distinguish between oxygenated blood, deoxygenated blood, blood with carbon monoxide, blood with oxidized hemoglobin and blood plasma. Signal data is obtained by passing various visible and infrared lights (LED's, 620 to 1270 mm) through a capillary bed (for example, a fingertip, a hand, a foot) and measuring changes in light absorption during the blood pulsatile cycle (see Figure 3). The photodetector receives the light, converts it into an electronic signal and sends it to the Radical 7/ Rad 87/ Rad-57t for calculation.
Once the instrument containing Rainbow SET technology receives the signal from the sensor, it utilizes Masimo Signal Extraction Technology (SET) to calculate the patient's functional oxygen saturation (SpO2), fractional concentration of carboxyhemoglobin (SpCO), fractional concentration of methemoglobin (SpMet), total hemoglobin concentration (SpHb) and pulse rate (PR). In instruments containing Masimo Rainbow SET technology. multi-wavelength calibration equations are used to estimate the saturation and concentration values.
#### Method of Operation
The Radical 7, Rad 87, and the Rad 57t have the same method of operation. The instrument is turned on. An oximetry sensor is attached to a patient's finger and one end of a patient cable is connected to the sensor and the other end connected to the instrument.
The monitor will begin continuously displaying the patient's pulse rate, and SpO2 value. Depending on the type and or configuration of the instrument, monitoring information would also include SpCO, SpMet, SpHb, PVI, and/or CaO2. The practitioner can the information to help assess the condition of the patient and as an aide in determining if any intervention is required by the practitioner.
Once the practitioner determines the patient no longer requires monitoring, the cable is disconnected from the sensor, the CO-oximetry sensor is removed (and disposed of if it is a single use device), and the power to the monitor is turned off.

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.
