Intended to add moisture to breathing gases for administration to pediatric through adult patients weighing ≥ 10 kg >1 month in homecare, hospital, extended care and hospice.
There are two models of the Hudson RCI Disposable Humidifier. Both models have identical intended uses and modes of operation. One model has a 4 PSI pressure relief valve (referred to as model 3230) and the other has a 6 PSI pressure relief valve (referred to as model 3260). Regardless of device model, the disposable humidifier delivers humidified gases to the patient. Both models of the non-prefilled disposable humidity in water vapor form to respiratory gases delivered to patients to make the gases more comfortable to breathe. The disposable humidifier incorporates a pressure relief valve with an audible alarm at 4 psi or 6 psi. depending on the model selected.
In both models, air is channeled through the water-containing bottle where it becomes humidified before exiting the device and being administered to the patient.
The patient can influence the use of these devices by occluding or loosening secure connections. In cases where the patient is also the user, over or under filling the device and selection of incorrect oxygen percent concentration and gas input pressures may influence the use of the device.
This is a 510(k) premarket notification for the "Hudson RCI® Disposable Humidifier with 4 PSI Pressure Relief Valve" and "Hudson RCI® Disposable Humidifier with 6 PSI Pressure Relief Valve". The document asserts substantial equivalence to the predicate device "Salter Labs Bubble Humidifier (K161719)".
However, the provided text does not contain a study that proves the device meets specific acceptance criteria in the format requested. Instead, it summarizes non-clinical testing performed to demonstrate safety based on industry standards and establish substantial equivalence to a predicate device.
The document lists various tests performed and standards utilized, but it does not provide:
- A table of acceptance criteria with reported device performance values against those criteria.
- Sample sizes used for test sets.
- Information about ground truth establishment, experts, or adjudication methods.
- Details about MRMC studies or effect sizes for AI assistance.
- Information on standalone algorithm performance or training set details.
The document provides a "Summary of Non-Clinical Testing" and then lists specific types of tests, such as "Humidification Output," "Flow Rate," "Alarm," and "Pull Test." While it states that the results of these tests indicate substantial equivalence, it does not detail the acceptance criteria for each test or the specific reported performance values that met those criteria.
Therefore, I cannot populate the requested table or provide the detailed information about study design, ground truth, and sample sizes that would typically be found in a study demonstrating device performance against acceptance criteria.
The information that is available regarding acceptance criteria and performance is very high-level and can be inferred from the "Comparison of Technological Characteristics" table and the "SUMMARY OF NON-CLINICAL TESTING" section:

Fisher & Paykel Healthcare RT330 Breathing Circuit and Optiflow Jr (Class I, 510(k) Exempt under 21 CFR 868.5340
The INOmax® DSIR Plus delivery system delivers INOMAX® (nitric oxide for inhalation) therapy gas into the inspiratory limb of the patient breathing circuit in a way that provides a constant concentration of nitric oxide (NO), as set by the user, to the patient throughout the inspired breath. It uses a specially designed injector module, which enables tracking of the ventilator waveforms and the delivery of a synchronized and proportional dose of NO. It may be used with most ventilators.
The INOmax® DSIR Plus provides continuous integrated monitoring of inspired O2, NO2, and NO, and a comprehensive alarm system.
The INOmax® DSIR Plus incorporates a battery that provides up to 6 hours of uninterrupted NO delivery in the absence of an external power source.
The INOmax® DSIR Plus includes a backup NO delivery capability that provides a fixed flow of NO which along with user supplied 10 L/min of oxygen provides 20 ppm in the gas flow to a patients breath. It may also use the INOblender® for backup.
The target patient population is controlled by the drug labeling for INOMAX® and is currently neonates. The primary targeted clinical setting is the Neonatal Intensive Care Unit (NICU) and secondary targeted clinical setting is the transport of neonates.
The INOmax DSR® Plus uses a "dual-channel" design to ensure the safe delivery of INOMAX®. The first channel has the delivery CPU, the flow controller and the injector module to ensure the accurate delivery of NO. The second channel is the monitoring system, which includes a separate monitor CPU, the gas cells (NO, NO2, and O2 cells) and the user interface including the display and alarms. The dual-channel approach to delivery and monitoring permits INOMAX® delivery independent of monitoring but also allows the monitoring system to shutdown INOMAX® delivery if it detects a fault in the delivery system such that the NO concentration could become greater than 100 ppm.
The INOmax® DSIR Plus delivery system delivers INOMAX® (nitric oxide for inhalation) therapy gas into the inspiratory limb of the patient breathing circuit in a way that provides a constant concentration of nitric oxide (NO), as set by the user, to the patient throughout the inspired breath. It uses a specially designed injector module, which enables tracking of the ventilator waveforms and the delivery of a synchronized and proportional dose of NO. It may be used with most ventilators.
The INOmax® DSIS Plus provides continuous integrated monitoring of inspired O2, NO2, and NO, and a comprehensive alarm system.
The INOmax® DSIR Plus incorporates a battery that provides up to 6 hours of uninterrupted NO delivery in the absence of an external power source.
The INOmax® DSIR Plus includes a backup NO delivery capability that provides a fixed flow of 250 mL/min of NO which along with user supplied 10 L/min of oxygen provides 20 ppm in the gas flow to a patients breathing circuit. It may also use the INOblender® for backup.
All revisions of INOmax DSm® Plus utilize component technology to deliver Nitric Oxide gas to the patient. The components consist of the Delivery System unit, the blender, a stand/cart and the NO gas tanks. In this revision of the INOmax DSm® Plus, the only changes to the device includes the labeling for compatibility with respiratory care device.
This document, K200389, is a 510(k) premarket notification for the INOmax DSIR Plus, a nitric oxide administration apparatus. It focuses on demonstrating substantial equivalence to a predicate device (K131686), specifically by adding compatibility with new ventilator and breathing devices.
Based on the provided text, the device performance assessment relies entirely on nonclinical (bench) testing and comparison to a previously cleared predicate device. There is no evidence of clinical studies involving human subjects or AI algorithms in this document. Therefore, many of the requested points regarding AI/MRMC studies, expert ground truth adjudication, and training/test set sample sizes are not applicable to the information presented.
Here's the breakdown of what can be extracted from the document:
1. A table of acceptance criteria and the reported device performance
The document does not provide a specific table of acceptance criteria with corresponding performance metrics like "accuracy > X%". Instead, it refers to a "Ventilator/Gas Delivery System Validation Test Protocol" used for the predicate device (K131686) and states that this same protocol, with "insignificant differences," was used for the INOmax DSIR Plus. The general acceptance criterion implied is that the device "performs within published specifications" and that "the hazards were mitigated" based on this protocol.
- Acceptance Criteria (Implied): Performance according to "published specifications" and mitigation of identified hazards, as demonstrated through the "Ventilator/Gas Delivery System Validation Test Protocol."
- Reported Device Performance: "Ultimately, the requirements necessary for the operation of the INOmax DSIR passed." and "This Bench Testing was conducted across all platforms to demonstrate that the INOmax DSIR® Plus performs within published specifications."
2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: Not explicitly stated as a number of patient cases or images. The "test set" in this context refers to the bench testing conducted on the device's compatibility with a list of new ventilator and breathing devices. The document lists 11 specific additional ventilator devices that were tested for compatibility:
- Covidien PB 980 (K131252)
- GE Healthcare Carescape R860 (K142679)
- Fisher & Paykel Healthcare RT330 Breathing Circuit and Optiflow Jr (Class I, 510(k) Exempt under 21 CFR 868.5340)
- Bunnell Inc Life Pulse 204 (P850064)
- Drager Perseus A500 (K133886)
- Fisher & Paykel Healthcare Airvo 2 (K131895)
- Drager Carina (K072885)
- Maquet Servo u/n (K151814)
- Hamilton C3 (K161450)
- IMT Medical Bellavista (K163127)
- Maquet Flow-i (K160665)
- Bio-Med TV-100 (K173973)
- Phillips V60 (K102985)
- Data Provenance: The data originates from bench testing (laboratory) rather than clinical patient data. Country of origin for the testing is not specified but is presumed to be associated with the manufacturer (Mallinckrodt Manufacturing, LLC, based in Madison, Wisconsin, USA). The testing is prospective in the sense of being conducted specifically for this submission, although it leverages a protocol from a previous clearance.
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)
Not applicable. This device is a hardware apparatus for administering nitric oxide, not an AI algorithm requiring expert human interpretation of medical images or data for ground truth. The "ground truth" for the nonclinical testing would be the engineering specifications and expected performance, verified through the validation protocol.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not applicable, as no human expert adjudication of data (like medical images or clinical outcomes) was performed. The "adjudication" of the bench test results would be whether the device passed or failed the predefined engineering/performance criteria in the validation protocol.
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
No. This document explicitly states, "The subject of this premarket submission... did not require clinical studies to support substantial equivalence." This means no human-in-the-loop performance study, MRMC study, or AI assistance was involved.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
No. This device is a physical medical device, not an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" used for this device's validation was engineering specifications and performance criteria established in the "Ventilator/Gas Delivery System Validation Test Protocol," likely determined by design requirements and regulatory standards for medical devices of this type.
8. The sample size for the training set
Not applicable. There is no AI component or training set mentioned in this submission.
9. How the ground truth for the training set was established
Not applicable. There is no AI component or training set mentioned in this submission.

ClearMate™ is intended to be used by emergency department medical professionals as an adjunctive treatment for patients suffering from carbon monoxide poisoning. The use of ClearMate" enables accelerated elimination of carbon monoxide from the body by allowing isocapnic hyperventilation through simulated partial rebreathing.
This device is intended to induce isocapnic hyperventilation in patients to speed up elimination of carbon monoxide (CO). Isocapnic hyperventilation can be defined as large increases in patient minute volume with minimal changes in arterial partial pressure of carbon dioxide (CO2). This device replaces CO2 levels in the airway, thereby maintaining CO2 levels in the blood that ultimately causes hyperventilation. This pneumatic device initially provides 100% supplemental oxygen (O2) at minute volumes selected based on patient weight. If the patient minute volume demand is more than the preset supplement O2 volume, this device supplies a mixture of 94%/6% (O2/CO2), which maintains CO2 levels in the airway to enable isocapnic breathing by partial simulated rebreathing (of CO2). This device consists of:
- The subject of this De Novo, the Control unit ("briefcase"), connects to sources of O2 and CO2 (neither gas is supplied with this device). The unit includes pressure gauges to read the source gas pressures. Internal components control supplemental gas flowrates, gas concentrations, and CO2 diversion away from the gas delivery pathway should O2 pressures be insufficient. This unit weighs about 2 kg and is pneumatically driven (i.e., no electronics).
- Two breathing circuits, which are not the subject of this De Novo, can attach to the gas outlet ports of the control unit. These circuits are constructed of reservoir bags (21 CFR 868.5320, Class I), oxygen cannulas (21 CFR 868.5340, Class I), masks (21 CFR 868.5550, cleared under K953107), valves (21 CFR 868.5870, cleared under K142402), resuscitation bags (21 CFR 868.5915, cleared under K912203), and/or tubing (21 CFR 868.5925, cleared under K161420).
- Hoses for source gas connections and a device stand for steadying the device, which are a subject of this De Novo.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
This device is not an AI/algorithm requiring expert-established ground truth for a test set in the diagnostic sense. The "ground truth" for its performance is derived from:
- Bench Testing: Engineering specifications and physical measurements. Experts involved would be engineering and quality control personnel. Their specific qualifications are not detailed, but they would be presumed to be qualified engineers/technicians.
- Animal Studies: Scientific observation and measurement by researchers/veterinarians.
- Human Clinical Studies: Clinical endpoints (e.g., COHb levels, elimination half-life, cerebral blood flow) measured by medical professionals and researchers. The peer-review process for these published studies implicitly involves expert clinicians and scientists.
4. Adjudication Method for the Test Set:
Not applicable, as this is not an AI/diagnostic algorithm using expert review for a "test set." For the literature review, the FDA's internal review team served as the adjudicators of the existing scientific evidence.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done:
No, an MRMC comparative effectiveness study, in the context of human reader performance with/without AI assistance, was not performed. The device is a physical therapeutic device, not a diagnostic AI system intended to assist human readers.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Yes, the device itself is the "standalone" component. Its performance was evaluated independently through bench testing (as detailed in item #2) and animal studies. The human clinical studies also assess the device's effect on physiological markers when used therapeutically.
7. The Type of Ground Truth Used:
- Bench Testing: Device specifications, physical properties, engineering standards, and direct measurement of gas concentrations, flow rates, and pressures.
- Animal Studies: Physiological measurements (e.g., COHb levels, cardiac output, oxygen delivery) directly measured from the animal subjects.
- Human Clinical Studies (for effectiveness): Physiological measurements (e.g., COHb levels, elimination half-life, cerebral blood flow) obtained from human volunteers or patients using established medical measurement techniques.
- Human Clinical Study (Wu et al. for safety, but with limitations on efficacy): Clinical outcomes adjudicated by medical personnel based on consciousness, continence, disappearance of CO poisoning signs, EEG findings, and BI (Barthel Index) scores.
8. The Sample Size for the Training Set:
Not applicable. This is a physical medical device, not an AI model requiring a training set in the machine learning sense. The device's design is based on scientific principles of isocapnic hyperventilation, not data training.
9. How the Ground Truth for the Training Set was Established:
Not applicable (as above). The design and performance targets for the ClearMate device are based on established physiological principles and engineering requirements, not on a "ground truth" derived from a training dataset for an AI algorithm.

The bubble humidifier is intended to add moisture to breathing gases for administration to patients >1 month in homecare, hospital, extended care and hospice.
The bubble humidifier is a non-sterile device indicated for single-patient usage. The device is indicated for patients who require humidification of high flow supplemental breathing gases.
The Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410 mbars) safety valve is an empty, disposable, non-sterile, not made with natural rubber latex, device intended to humidify breathing gas prior to delivery to a patient. The Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve is provided with a 6 pounds per square inch (PSI) safety valve and can operate within flow rates of 6 to 15 liters per minute (LPM). The device is used with various breathing gas sources (i.e., oxygen concentrators, gas cylinders and wall outlets) and provides connection for delivery of humidified breathing gas via face masks or cannulas, and use of optional oxygen tubing and water traps (face masks, 21 CFR 868.5580: nasal cannulas, 21 CFR 868.5340; oxygen tubing, 21 CFR 868.5860 and water traps, 21 CFR 868.5995 are 510(k) exempt).
This device is a passive device and is not a cascade humidifier, is not heated and is not prefilled.
The device is made of a humidifier bottle which is used to hold water during use, a lid which seals the humidifier bottle, an audible pressure relief mechanism to notify the user of a downstream occlusion and a diffuser located at the end of a PVC diffuser tube inside the humidifier bottle. The diffusor is designed to uniformly disperse the gas throughout the water. Both the bottle and lid are constructed to be easy to grip and reduce the chance of cross threading. The bottle is permanently marked with "minimum/maximum" water levels. The lid is marked with minimum source pressure, flow ranges and pressure value of the safety valve.
The provided document describes a 510(k) premarket notification for a medical device, specifically a "Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve." This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than proving novel safety and effectiveness through extensive clinical trials. Therefore, the device acceptance criteria and study information provided are tailored to this regulatory pathway, primarily involving performance testing and biocompatibility assessments related to a material change.
The document does not describe the development or evaluation of an Artificial Intelligence (AI) device. Consequently, several of the requested categories (e.g., sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC comparative effectiveness study, standalone performance, training set size, and ground truth for training set) are not applicable to this submission.
Here's an analysis of the provided information, addressing the relevant points:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are implicitly derived from the performance specifications of the predicate device and relevant international standards. The "Performance Data" section indicates that the focus was on verifying that the material change did not adversely affect performance.

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample size for the performance tests conducted on the modified device (e.g., bond strength, cleaning, useful life studies). However, such tests would typically involve a statistically relevant number of units.
- Data Provenance: The tests were conducted internally by Salter Labs, the manufacturer. No country of origin for test data is specified beyond the manufacturer's location in Carlsbad, California, USA. The studies are prospective in the sense that they were designed and executed to evaluate the modified device.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This question is not applicable. The studies involved physical and chemical testing of the device, not the establishment of ground truth by human experts, as would be the case for diagnostic AI.
4. Adjudication Method for the Test Set
This question is not applicable. The tests involved objective physical and chemical measurements against predetermined specifications, not subjective interpretation requiring 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
This question is not applicable. This is not an AI device, and therefore, no MRMC study or assessment of human reader improvement with AI assistance was performed.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This question is not applicable. This is not an AI device.
7. The Type of Ground Truth Used
The "ground truth" for this device's evaluation is based on:
- Established Performance Specifications: For parameters like flow rate, pop-off pressure, and mechanical integrity (bond strength), the "ground truth" refers to the pre-defined engineering and performance specifications that the device must meet, often derived from the predicate device's performance or relevant industry standards.
- International Standards (Biocompatibility): For biocompatibility, compliance with ISO 10993 standards (e.g., negative cytotoxicity, no irritation/sensitization) serves as the "ground truth."
8. The Sample Size for the Training Set
This question is not applicable. This is not an AI device; therefore, there is no AI model requiring a training set.
9. How the Ground Truth for the Training Set Was Established
This question is not applicable. There is no training set for an AI model.

design and construction of the nasal cannula is almost identical to the nasal oxygen cannula 21 CFR 868.5340
design and construction of the nasal cannula is almost identical to the nasal oxygen cannula 21 CFR 868.5340
THE MICROSTREAM FILTERLINE NC DEVICE IS USED WHENEVER THE PHYSICIAN NEEDS TO MEASURE THE CO₂ IN A PATIENT'S BREATHING IN A NON INTUBATED PATIENT.
The common product name for this device is a gas sampling nasal cannula . The gas sampling nasal cannula is used with a capnograph (carbon dioxide analyzer 21CFR 868.1400). There is a nasal cannula at one end of the device for connecting to the patient's nose and a female Luer lock on the Other end for connecting to the capnograph. The design and construction of the nasal cannula is almost identical to the nasal oxygen cannula 21 CFR 868.5340. The main difference is that instead of flowing oxygen through the cannula to the patient we use a vacuum to draw a sample of the breathing from the patient.
The two connectors are joined by a plastic tube and an in line hydrophobic filter.
One end of the tube is connected to the source of the patient's breathing (exhalation) and the other end of the tube is connected to a capnograph. The capnograph has a pump that creates a vacuum of approximately 30mbar which draws a sample of the patient's Breathing (exhalation) through the sampling tube into the capnograph for analysis of the CO2 content of the patient's exhalation.
The anesthesiologist sometimes places a hydrophobic filter between the sample line and the capnograph to keep moisture from entering the capnograph. The microstream nasal cannula filterline has integrated an in line hydrophobic filter between the patient and the capnograph to reduce the amount of patient generated moisture that can enter the capnograph.
The provided text describes a 510(k) submission for a medical device called the "Microstream Nasal Cannula Filterline." This submission focuses on establishing substantial equivalence to a previously approved device rather than presenting a de novo study with specific acceptance criteria and performance metrics.
Therefore, many of the requested details about acceptance criteria, study design, sample sizes, and ground truth cannot be extracted from this document, as it is not a clinical study report.
Here's an analysis of the provided information relative to your request:
1. A table of acceptance criteria and the reported device performance
- Not Applicable. The document does not provide a table of acceptance criteria or performance metrics. This submission is for a 510(k) and relies on demonstrating "substantial equivalence" to a predicate device (K964239), not on proving specific performance against predefined criteria in a new clinical study. The FDA's letter states, "we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976..."
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not Applicable. There is no mention of a test set with a specific sample size. The submission is based on the claim that the device is "identical to the same device described as an accessory to the NPB-75/microcap capnograph/pulse oximeter in approved submittal K964239." This implies that the performance data for the predicate device is being leveraged, rather than new performance data for this specific accessory.
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)
- Not Applicable. No ground truth establishment is described, as there is no new test set or clinical study presented in this document.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable. No test set or adjudication method is described.
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 gas sampling line accessory for a capnograph, not an AI-powered diagnostic tool. Therefore, an MRMC study related to AI assistance is irrelevant and not mentioned.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. This is a hardware accessory, not an algorithm. Standalone performance as described is not relevant.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Not Applicable. No ground truth is described because no new clinical study is presented for this 510(k). The basis for approval is substantial equivalence to a predicate device.
8. The sample size for the training set
- Not Applicable. This device is a physical accessory, not a machine learning algorithm. Therefore, there is no "training set" in the context of AI.
9. How the ground truth for the training set was established
- Not Applicable. As above, there is no training set for this type of device.
Summary of available information:
The document is a 510(k) premarket notification for a Class II medical device (Microstream Nasal Cannula Filterline). Its purpose is to demonstrate substantial equivalence to an already approved predicate device (mentioned in K964239). The device is a "gas sampling nasal cannula" designed to conduct a sample of the patient's breathing from the nose to a capnograph for CO2 measurement, featuring an integrated hydrophobic filter. The FDA found the device substantially equivalent.
No clinical study data, performance metrics, or specific acceptance criteria are provided in this submission, as the regulatory pathway chosen (510(k)) for this type of device relies on demonstrating equivalence rather than conducting new efficacy or performance trials.
