The Capnostream®20p combined capnograph/pulse oximeter monitor and its accessories are intended to provide professionally trained health care providers with continuous, non-invasive measurement and monitoring of carbon dioxide concentration of the expired and inspired breath and respiration rate, and with continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate. It is also indicated for continuous non-invasive monitoring of carboxyhemoglobin saturation (measured by an SpCO/SpMet/SpHb sensor), methemoglobin saturation (measured by an SpCO/SpMet/SpHb sensor) and total hemoglobin concentration (measured by an SpCO/SpMet/SpHb sensor). It is intended for use with neonatal, pediatric, and adult patients in hospital-type facilities, intra-hospital transport and home environments.
The Capnostream®20p monitor provides the clinician with an integrated pulmonary index (IPI). The IPI is based on four parameters provided by the monitor: end tidal carbon dioxide, respiration rate, oxygen saturation and pulse rate. The IPI is a single index of an adult or pediatric patient's ventilatory status displayed on a scale of 1 - 10, where 10 indicates optimal pulmonary status. IPI monitoring displays a single value that represents the patient's pulmonary parameters and alerts clinicians to changes in the patient's pulmonary status.
The IPI is an adjunct to, and is not intended to replace, vital sign monitoring.
The Capnostream20p bedside monitor is a two parameter monitor consisting of a microMediCO2 capnography module and/or a pulse oximetry module implemented in a host device. The host device displays parameters received from the respective modules and generates alarms when preset alarm thresholds are crossed. The device is classified as CCK Class II according to 21 CFR § 868.1400 - Carbon Dioxide Analyzer with DQA 21 CFR § 870.2700 Pulse Oximeter listed as an additional or alternate classification.
This device has two modules that are classified as follows:
- 21 CFR 868.1400, Carbon Dioxide Analyzer (Classification CCK) .
- . 21 CFR 870.2700 Pulse Oximeter (Classification DQA).
Each module is controlled by dedicated software that is an integral part of the respective module. Each module provides parameters to the host software (the Capnostream20p device software) which then controls the display of the received parameter values and creates alarms when the values cross the preset thresholds.
The microMediCO2 module provides the following inputs to the host monitor: FiCO2, EtCO2 numeric, EtCO2 waveform, Respiratory Rate, IPI (Integrated Pulmonary Index).
The Masimo MX1 SpO2 module, integrated in the Capnostream20 p monitor presented in this submission, provides the following parameters to the host for display: SpO2 (functional oxygen saturation of arterial hemoglobin), pulse rate, SpCO (carboxyhemoglobin saturation in blood), SpMet (methemoglobin saturation in blood) and SpHb (total hemoglobin concentration in blood).
The host monitor will display this data to the user in numerics via a screen, and will also display the CO2 waveform and SpO2 (pleth) waveform or pulse bar graph.
The three measurements will be available both real time and in trend summaries.
In addition, the MX1 board provides a Perfusion Index (PI) indicating the relative pulsatile strength at the sampling site is provided to the host monitor for display.
The host displays the Rainbow SET parameters values on the screen alongside the four IPI (Integrated Pulmonary Index) parameters and the IPI value as presented on the predicate device.
This 510(k) summary describes a device, the Capnostream®20p with Masimo MX1 SpO2 board, which is a combined capnograph/pulse oximeter monitor. The submission seeks to prove its substantial equivalence to predicate devices, particularly concerning the addition of three new parameters: SpCO, SpMet, and SpHb.
Based on the provided text, the device itself is a medical monitor, not an AI or algorithm-based diagnostic tool that would typically undergo studies to demonstrate performance against established acceptance criteria in the manner requested. The document focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific clinical acceptance criteria for new functionality.
Therefore, many of the requested categories (like sample size for test sets, number of experts, adjudication methods, MRMC studies, standalone algorithm performance, training set details, and ground truth establishment for training) are not applicable or explicitly mentioned in the provided regulatory submission for this type of medical device.
However, I can extract the relevant information regarding performance, a comparison to predicate devices, and the intended use.
Acceptance Criteria and Device Performance Study Summary
The submission does not present a study with specific acceptance criteria in the format of a diagnostic algorithm or AI performance evaluation. Instead, it asserts substantial equivalence to existing predicate devices based on design, intended use, and adherence to performance and safety standards. The "performance" in this context refers to the device's ability to accurately measure the stated physiological parameters in line with its predicate devices and relevant standards.
The primary document provided is a "Traditional 510(k) Submission," which aims to demonstrate that a new device is as safe and effective as a legally marketed predicate device. This is typically achieved through engineering and verification/validation testing against standards, rather than large-scale clinical trials establishing new performance benchmarks.
1. A table of acceptance criteria and the reported device performance:
Since specific acceptance criteria for a new clinical performance study (like sensitivity/specificity targets) for this device are not presented, the table below reflects the comparison to predicate device characteristics and adherence to recognized standards, which serve as the "acceptance criteria" for a 510(k) submission of this nature.
| Feature / Criteria | Acceptance (Predicate Device Equivalent) | Reported Device Performance (Capnostream20p with Masimo MX1 SpO2 board) |
|---|---|---|
| Indications for Use | The Capnostream®20p combined capnograph/pulse oximeter monitor is intended for continuous, non-invasive measurement and monitoring of carbon dioxide concentration, respiration rate, functional oxygen saturation (SpO2), and pulse rate. Intended for neonatal, pediatric, and adult patients in hospital-type facilities, intra-hospital transport, and home environments. It also includes an Integrated Pulmonary Index (IPI). | Identical, with the addition of continuous non-invasive monitoring of carboxyhemoglobin saturation (SpCO), methemoglobin saturation (SpMet), and total hemoglobin concentration (SpHb), measured by an SpCO/SpMet/SpHb sensor. All other indications for use, patient populations, and environments remain the same as the predicate. The device still provides IPI based on the four core parameters. |
| Target Population | It is intended for use with neonatal, pediatric, and adult patients. | Identical. |
| Design | Equivalent to the Capnostream20 (K094012). | Equivalent to the Capnostream20 described in K094012, with the addition of the Masimo MX1 SpO2 board enabling the measurement of SpCO, SpMet, and SpHb. |
| Performance Standards | ISO 21647, ISO 9919 | Adherence to ISO 21647 and ISO 9919. The three new parameters (SpCO, SpMet, SpHb) "have been clinically validated by Masimo Corporation" (a separate predicate device, K080238). |
| Safety Standards | IEC/EN 60601-1, IEC/EN 60601-1-2, IEC 60601-1-8, UL 60601-1, ISO 14971, EN 980 | Adherence to IEC/EN 60601-1, IEC/EN 60601-1-2, IEC 60601-1-8, ISO 14971, EN 980 (UL 60601-1 not explicitly listed for new device, but other safety standards are identical or similar). Hazard analysis was performed, concluding residual risks were acceptable. |
| Software Functional Equivalence | Software for predicate controls display of parameters and alarms. | Software testing was performed to validate the performance of the new monitor software and its substantial equivalence to the predicate device, including display of new parameters and alarms. |
| Clinical Validation of New Parameters | (Not applicable for predicate device as these parameters were not included) | The new parameters (SpCO, SpMet, SpHb) were originally clinically validated by Masimo Corporation for their predicate device (K080238). The current submission leverages this existing validation for the module integrated into the Capnostream20p. |
| Overall Safety & Effectiveness | Existing legally marketed predicate devices are safe and effective. | Capnostream20p with Masimo MX1 SpO2 board functionality does not raise any new potential safety risks and is equivalent in performance to the existing legally marketed devices. It is substantially equivalent to the predicate devices with respect to safety, effectiveness, and intended use. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- The document primarily references software testing and adherence to standards for the Capnostream20p device itself. No specific clinical test set sample sizes for the overall device's performance (beyond the existing Masimo validation for the SpCO/SpMet/SpHb module) are provided in this summary.
- The data provenance for the clinical validation of SpCO, SpMet, and SpHb, if conducted by Masimo, is not detailed in this submission. It relies on the prior clearance (K080238) of the Masimo device.
- The document does not specify whether any de novo clinical studies for this specific integrated device were prospective or retrospective.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
- This information is not provided in the summary. For a 510(k) submission showing substantial equivalence for a monitoring device, ground truth established by experts in this manner is not typically required or presented unless new clinical performance (e.g., diagnostic accuracy) is being claimed for a novel algorithm.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- This information is not provided, as the submission does not detail a clinical study with expert adjudication.
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 is a medical monitoring device, not an AI diagnostic algorithm, and no MRMC study or AI assistance is mentioned.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable in the typical sense for an AI algorithm. The device itself is a "standalone" monitor that provides continuous measurements. The "performance" is its intrinsic measurement accuracy against physical standards and clinical correlation, as established by the predicate devices. The new SpCO/SpMet/SpHb parameters are derived from the Masimo MX1 SpO2 board, which would have undergone its own standalone validation.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For the core capnography and pulse oximetry functions, ground truth would typically be established through physical gas standards for CO2, and controlled blood gas analysis and controlled hypoxia/hyperoxia studies for SpO2, matched against invasive measurements, as per ISO standards.
- For the added SpCO, SpMet, and SpHb parameters, the submission states these "have been clinically validated by Masimo Corporation." Such validation would typically involve co-oximetry blood sampling as the ground truth against the non-invasive measurements from the Masimo sensor.
8. The sample size for the training set:
- This information is not applicable and not provided. The device does not appear to employ machine learning that would require a separate "training set" in the context of an AI algorithm.
9. How the ground truth for the training set was established:
- Not applicable, as no training set for an AI algorithm is mentioned.
