The provided document is a 510(k) clearance letter and summary for the Medical Gas Analyzer (AG200). It does not contain information about a study proving the device meets its acceptance criteria.
The document states: "the subject device does not require clinical test data to support substantial equivalence." This means that the device was cleared based on its similarity to existing devices and bench testing, rather than a clinical study demonstrating its performance against specific acceptance criteria in a real-world setting.
Therefore, I cannot provide the requested information about the study proving the device meets acceptance criteria, the sample sizes, data provenance, expert details, adjudication methods, MRMC study results, standalone performance, or training set details as they are not present in the provided text.
However, I can extract the acceptance criteria as reported in the document through comparison with the predicate device, although these are not explicitly presented as "acceptance criteria" but rather as "device performance" parameters.

The Nihon Kohden TG-980P/TG-980P1 CO2 Sensor Kit is intended for medical purposes to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory status.
Along with other methods indicated by the physician for medical diagnosis, this device is intended as an indicator of patient carbon dioxide concentration during expiration. The device is intended for use by qualified medical personnel within a hospital, ambulatory care, transport, or any other clinical environment.
The TG-980P and TG-980P1, collectively referred to as TG-980P/TG-980P1, are CO2 Sensor Kits used to measure the concentration of carbon dioxide (CO2 or CO2) during patient expiration. The TG-980P/TG-980P1 is intended for use by qualified medical personnel as an aid for determining patient ventilatory status within a hospital, ambulatory care, transport, or any other clinical environment.
The TG-980P/TG-980P1 CO2 Sensor Kit comprises three main components: a CO2 sensor, an interface connector, and a sensor cable. It utilizes the mainstream measurement method to sample gas directly from the patient's airway and non-dispersive infrared (NDIR) absorption technology to measure CO2 concentration during patient expiration. CO2 gas absorbs infrared light at specific wavelengths, and the amount absorbed is directly related to CO2 concentration. The CO2 sensor is equipped with a light source that generates infrared light. The light passes through an attached Nihon Kohden accessory (except the Thermal Airflow Sensor) through which the expired air flows and is converted by photodetectors to voltage, which is used to calculate CO2 concentration. The calculated digital data is then transmitted and displayed on a connected patient monitor or other device.
The TG-980P/TG-980P1 CO2 Sensor Kit can be connected via the interface connector and used with Nihon Kohden devices for which the operator's manual specifies compatibility with the TG-980P/TG-980P1.
This FDA 510(k) clearance letter pertains to a hardware device (CO2 Sensor Kit) and not an AI/ML software. Therefore, many of the requested criteria regarding AI-specific studies (e.g., sample size for training set, number of experts for ground truth, MRMC study) are not applicable.
However, I can extract the relevant acceptance criteria and details of the non-clinical performance studies conducted for the device.

The Oxy2Pro is a single patient, disposable procedural mask with access for the insertion of oral scopes, probes, delivery of supplemental oxygen and monitoring breathing by providing a means to sample exhaled CO2. It is for nonintubated, adult patients who are breathing spontaneously.
The Southmedic Oxy2Pro is designed to have a flexible, thin membrane that is intended to be breached when requiring oral access for scope entry. This slitted membrane is intended to allow the mask to return to a closed- mask functionality after having been used with a scope. This device is to be used in conjunction with FDA cleared capnographs.
Here's a breakdown of the acceptance criteria and study information for the Oxy2Pro device, based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The document states that the acceptance criteria for the Oxy2Pro mask was that its performance for FiO2 (fraction of inspired oxygen) and EtCO2 (end-tidal carbon dioxide) should not be statistically significantly less than the predicate device (K172365) at the tested flow rates.
The study results demonstrate the following:
Oxygen Flow Rate | Oxy2Pro FiO2 | Oxy2Pro EtCO2 | Predicate (K172365) FiO2 | Predicate (K172365) EtCO2 |
---|---|---|---|---|
5 l/min | 53.3% | 6.13% | N/A | N/A |
8 l/min | 64.0% | 4.87% | 52.3% | 4.03% |
10 l/min | 64.7% | 4.70% | 48.3% | 4.17% |
12 l/min | 67.3% | 3.77% | 54.7% | 3.30% |
15 l/min | 72.3% | 3.70% | 52.0% | 3.53% |
The document concludes that the "Oxy2Pro mask was not statistically significantly less than the predicate for FiO2 or EtCO2 at the tested flow rates, meeting the acceptance criteria."
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: Not explicitly stated in terms of a number of masks or subjects. The document mentions "testing was completed under simulated conditions at various flow rates." This implies a series of measurements were taken at different flow rates, but the number of devices tested or repetitions of each test is not specified.
- Data Provenance: The testing was "completed to evaluate the ability to deliver FiO2 and sample EtCO2 relative to the predicate device." It was performed by an "Accredited third-party testing" organization. The location of this organization and whether the data is retrospective or prospective is not specified. Given the context of a 510(k) submission, it is likely prospective testing specifically conducted for this submission.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
N/A. This information is not relevant or applicable to the type of performance testing described. The "ground truth" (or reference standard) in this context is the measured FiO2 and EtCO2 values under controlled simulated conditions, using calibrated equipment. It does not involve expert interpretation or consensus.
4. Adjudication Method for the Test Set
N/A. As the testing involved objective measurements under simulated conditions, there was no need for an adjudication method by experts.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
N/A. This type of study is typically performed for AI/image analysis devices where human readers provide interpretations. The Oxy2Pro is a medical device for oxygen delivery and CO2 sampling, and its performance is evaluated objectively through physical measurements, not human interpretation.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
N/A. This concept is for software algorithms. The Oxy2Pro is a physical device; its performance is standalone in the sense that it functions physically to deliver oxygen and sample gas.
7. Type of Ground Truth Used
The ground truth used was simulated conditions with true baseline EtCO2 at 5%. This implies a controlled environment where the actual concentration of inspired oxygen and exhaled CO2 was known and measured with high precision using reference instruments.
8. Sample Size for the Training Set
N/A. The Oxy2Pro is a physical medical device, not an AI or machine learning algorithm, so there is no training set in this context.
9. How the Ground Truth for the Training Set Was Established
N/A. As there is no training set, this question is not applicable.

2. Sample Size Used for the Test Set and Data Provenance
The document does not specify a distinct "test set" in terms of patient data or a specific number of devices. The performance testing appears to be primarily laboratory-based comparisons between the proposed device and the predicate.
- Test Set Sample Size: Not explicitly stated for performance tests. The comparison of physical measurements, CO2 sampling, and O2 flow rates implies a limited number of devices were tested against each other.
- Data Provenance: Not applicable in the context of patient data for the performance comparison. The tests were likely conducted in a controlled lab environment. The document states "Age testing done with cannulas manufactured in 2019" which suggests a retrospective analysis of previously manufactured devices for aging studies.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This is not a study requiring expert clinical assessment for ground truth. The performance testing involves objective measurements (e.g., CO2 levels, O2 flow, physical dimensions) and adherence to standards (e.g., ISO 10993, ISO 18562).
4. Adjudication Method for the Test Set
Not applicable. There is no clinical imaging or diagnostic interpretation involved that would require an adjudication method like 2+1 or 3+1.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device is a medical accessory for delivering oxygen and sampling CO2, not an AI-powered diagnostic tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This is a hardware device, not an algorithm.
7. The Type of Ground Truth Used
- For Biocompatibility: Compliance with international standard ISO 10993-1 and ISO 18562. This represents established biological safety standards.
- For Performance Testing (CO2, O2, Physical): Comparison against the performance of the legally marketed predicate device (K010024 Oridion Nasal CO2/O2 Cannula). The predicate device's performance established the "ground truth" or benchmark for equivalence.
- For Age Testing/Shelf Life: Laboratory-based aging studies where the performance of aged devices is compared to new devices (and found equivalent to "cannulas manufactured in 2022").
8. The Sample Size for the Training Set
Not applicable. This is a hardware device, not a machine learning algorithm that requires a training set.
9. How the Ground Truth for the Training Set was Established
Not applicable.

Intended use The Dräger CO2 Mainstream Sensor for measuring the CO2 concentration in breathing gas (CO2 mainstream sensor).
Indications The CO2 mainstream sensor enables the diagnosis and monitoring of patients by measuring CO2. The use of the medical device is limited to one patient at a time.
The CO2 Mainstream Sensor is designed for continuous, non-invasive mainstream measurement of Carbon Dioxide. The sensor is able to monitor CO2 using an infrared absorption technique and measures end tidal CO2 and inspired CO2 and calculates the respiratory rate. The data are processed by a microcontroller and provided to the parent device via a serial interface.
The sensor is adapted to the breathing system by airway adapters (CO2 measuring cuvettes).
Here's a summary of the acceptance criteria and study information for the CO2 Mainstream Sensor, based on the provided FDA 510(k) premarket notification:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly present a table of acceptance criteria for specific performance metrics of the CO2 Mainstream Sensor with corresponding reported values in a consolidated format. However, it mentions extensive testing against various standards, which imply certain performance criteria. The key performance-related mention is the "Measuring range," which has been slightly extended compared to the predicate device.
Performance Metric | Acceptance Criteria (Implied by Predicate/Standards) | Reported Device Performance |
---|---|---|
Measuring range | 0 to 13.2 Vol.%, 0 to 13.3 kPa, 0 to 100 mmHg | 0 to 15.8 Vol% (at 1013 hPa), 0 to 16.0 kPa, 0 to 120 mmHg |
Respiratory Rate Range | 0 to 150 /min | 0 to 150 /min |
Operating Temperature | -20 to +50 °C (-4 to 122 °F) | -20 to +50 °C (-4 to 122 °F) |
Operating Humidity | 5 to 95 %, non-condensing | 5 to 95 %, non-condensing |
Operating Ambient Air Pressure | 57 - 110 kPa (K100941) / 570 to 1100 hPa (428 to 825 mmHg) | 570 to 1100 hPa (428 to 825 mmHg) |
Protection against penetrating liquids | IP64 | IP64 |
Electrical Safety | Conformance to IEC 60601-1-6, IEC 60601-1-12 | Tested and Conforms |
EMC | Conformance to IEC 60601-1-2, IEC/TR 60601-4-2 | Tested and Conforms |
Biocompatibility | Conformance to ANSI AAMI ISO 10993-1 | Tested and Conforms |
Software | Conformance to ANSI AAMI IEC 62304 | Tested and Conforms |
Usability | Conformance to IEC 60601-1-6, AAMI / ANSI / IEC 62366-1 | Tested and Conforms |
Risk Management | Conformance to ANSI AAMI ISO 14971 | Tested and Conforms |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample size for specific performance tests or studies like clinical trials in terms of the number of patients or specific data points. The testing mentioned is primarily bench testing and in vitro evaluations against technical standards and requirements.
The data provenance is not specified beyond indicating "extensive testing" and "well-established methods." It's reasonable to infer these tests were conducted by the manufacturer (Drägerwerk AG & Co. KGaA) in Germany, given the submitter's location. The studies appear to be retrospective in nature, drawing from the predicate device's established performance and applying new testing to demonstrate equivalence or improvement.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The document does not mention the use of experts to establish ground truth for testing in the context you describe (e.g., radiologists for image interpretation). The testing conducted is primarily objective, technical verification and validation against pre-defined standards and specifications for a CO2 sensor. Therefore, the "ground truth" for the test set would be derived from:
- Reference gases with known concentrations for CO2 measurements.
- Calibrated instruments for temperature, humidity, pressure, and electrical measurements.
- Standardized test procedures and benchmarks for software, EMC, and safety.
4. Adjudication Method for the Test Set
No adjudication method (e.g., 2+1, 3+1) is mentioned, as this type of human expert consensus is not typically applicable to the kind of technical and bench testing described for this device. Test results would be compared directly to the specified standards and requirements.
5. If a Multi-reader Multi-case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not done. This type of study is more common for diagnostic imaging devices where human interpretation plays a significant role. The CO2 Mainstream Sensor is a measurement device where its output is directly read rather than interpreted by multiple human readers in a comparative setting.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, the testing described appears to be primarily standalone performance testing, focusing on the algorithm (implicitly, the sensor's measurement principle and data processing) and hardware of the device itself. The "Discussion of Non-clinical Testing" section lists various technical evaluations, including software, electrical safety, EMC, and specific performance requirements from ISO 80601-2-55 for respiratory gas monitors. These are conducted on the device's inherent capabilities without human intervention for interpretation as part of the performance evaluation.
7. The Type of Ground Truth Used
The ground truth used for the technical testing would be:
- Reference Standards: Such as known concentrations of CO2 for accuracy testing, established environmental conditions (temperature, humidity, pressure), and defined electrical safety limits.
- Calibration Standards: High-precision instruments used to calibrate and verify the accuracy of the sensor's measurements.
- Compliance to Standards: The device's performance is measured against predefined thresholds and specifications outlined in the various IEC and ISO standards listed (e.g., ISO 80601-2-55 specific requirements for respiratory gas monitors).
8. The Sample Size for the Training Set
This device appears to be based on an established measurement principle (infrared absorption), and the submission focuses on demonstrating substantial equivalence through non-clinical testing rather than development of a novel algorithm that would require a "training set" in the machine learning sense. Therefore, there is no mention of a training set sample size as it's not applicable to the development verification of this type of device.
9. How the Ground Truth for the Training Set Was Established
As there is no "training set" mentioned in the context of machine learning, this question is not applicable to the information provided. The principles the device operates on are well-understood physics, and the validation relies on meeting established technical specifications and standards rather than learning from a dataset.

The Endoscopy Oxygen Mask is a single patient, disposable device intended for delivering supplemental oxygen and monitoring expired gases from the patient, with ports to allow the clinician to insert scopes, probes, or tubes. It is for non-intubated, spontaneously breathing patients greater than 30 kg.
The Endoscopy Oxygen Mask is a multi-port mask that serves several functions: A standard oxygen mask for when a patient requires supplemental oxygen; Sampling of exhaled gases for monitoring, typically end-tidal CO2; Additional ports (membranes) to allow for most types of scopes, probes, and tubes to be inserted while still delivering supplemental O2 and sampling exhaled gases.
The provided document describes the Endoscopy Oxygen Mask (K220533) and its substantial equivalence to a predicate device, the Panoramic Oxygen Mask (POM) (K172365). The acceptance criteria for the new device are primarily demonstrated through comparative non-clinical testing against the predicate device, showing similar performance in key aspects.
Here's a breakdown of the requested information:
1. A table of acceptance criteria and the reported device performance
The document doesn't explicitly state "acceptance criteria" in a numerical or pass/fail format for each performance metric. Instead, it relies on demonstrating similarity or equivalence to the legally marketed predicate device (K172365) through non-clinical comparative testing. The performance is reported in terms of this similarity.
Acceptance Criteria (Inferred from Comparison to Predicate) | Reported Device Performance (Endoscopy Oxygen Mask) |
---|---|
Indications for Use: Single patient, disposable device intended for delivering supplemental oxygen and monitoring expired gases from the patient, with ports to allow the clinician to insert scopes, probes, or tubes for non-intubated, spontaneously breathing patients > 30 kg. | Similar to predicate. |
