It is intended for use in patients requiring oxygen therapy to improve blood oxygen levels while monitoring expired gas to determine ventilatory rate. ## Device Story Nasal cannula with bifurcated nares; delivers low-flow oxygen to nasal pharynx via lower halves of nasal prongs; simultaneously samples exhaled gas via upper halves of both nasal prongs. Connected to external expiratory gas monitor via small-bore sampling line. Used in clinical settings for patients requiring oxygen therapy; operated by healthcare providers. Device facilitates continuous oxygen delivery and monitoring of ventilatory rate; improves blood oxygen levels while providing respiratory status data. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Bifurcated nasal cannula; dual-lumen design for simultaneous oxygen delivery and gas sampling through both prongs. Non-electronic, mechanical device. No specific materials or standards cited. ## Regulatory Identification A carbon dioxide gas analyzer is a device intended to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory, circulatory, and metabolic status. The device may use techniques such as chemical titration, absorption of infrared radiation, gas chromatography, or mass spectrometry. ## Predicate Devices - SALTER LABS Oxygen Delivery - CO₂ Sampling Nasal Cannula ([K892406](/device/K892406.md) and [K863883](/device/K863883.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Box 9020 Temecula, California 92589-9020 Tel: (909) 676-5611 Fax: (909) 676-1578 **Official Contact:** Arden Morley Director of Regulatory Affairs **Proprietary or Trade Name:** CO₂, Oxygen Nasal Cannula **Common/Usual Name:** Cannula **Intended Device:** CO₂, Oxygen Nasal Cannula **Predicate Device:** SALTER LABS Oxygen Delivery - CO₂ Sampling Nasal Cannula K 892406 and K 863883 ## Device Description The Hudson RCI nasal cannula with gas sampling port has bifurcated nares that channel oxygen delivery through both nasal prongs while allowing sampling of the patient's exhaled gas from both nasal prongs. Oxygen is delivered to the Cannula during all phases of ventilation through the base of the cannula and is directed through the lower halves of each nasal prong into the nasal pharynx. During exhalation, oxygen continues to flow into the nasal pharynx through these lower prong halves. When the gas sampling line is connected to an expiratory gas monitor, a small amount of gas is continuously withdrawn from the nasal pharynx through the upper halves of both nasal prongs. Part of this gas exits one side of the cannula and is routed via a small-bore gas sampling line to the expired gas monitor. ## Intended Use The Hudson RCI Cannula is an adjunct to oxygen therapy with its primary function being that of delivering low flow oxygen to a patient while providing a means to sample expired gas. It is intended for use in patients requiring oxygen therapy to improve blood oxygen levels while monitoring expired gas to determine ventilatory rate. No difference in intended use between the Hudson RCI and Salter Labs product has been identified. ## Patient Population The Cannula may be used on patient populations ranging from infant to adults that require low flow oxygen therapy and expired gas monitoring. No difference in patient population between the Hudson RCI and Salter Labs product has been identified. 60 {1} DSMA - Summary of Safety and Effectiveness for Hudson RCI ETCO $_2$ , Oxygen Nasal Cannula Page 2 of 2 ## Comparison of Technological Characteristics The Cannula is a modification of feature and design of the SALTER LABS Oxygen Delivery/CO $_2$ Sampling Cannula. The main difference between the Cannula and the predicate device is that the latter delivers oxygen through one nasal prong and samples CO $_2$ from the other prong while the Hudson RCI Cannula will perform both functions through each nasal prong. However, the Hudson RCI Cannula and predicate device Cannula operate in a similar manner in that they each deliver a gas, usually oxygen, while providing a means to sample exhaled gas. No difference in technological characteristics between the Hudson RCI and Salter Labs product that would affect safety or effectiveness has been identified. ## Conclusion Hudson RCI has designed and manufactured the Cannula to objective criteria and believes that it is substantially equivalent to the SALTER LABS Oxygen Delivery $\mathrm{CO}_{2}$ Sampling Cannula which has been identified as a legally marketed predicate device. {2} DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 JUN 5 2001 Ms. Sheryl Saenz Hudson Respiratory Care, Inc. 27711 Diaz Road P.O. Box 9020 Temecula, CA 92589 Re: K961150 Trade/Device Name: Double Lumen Oxygen Delivery Gas Sampling Nasal Cannula Regulation Number: 868.1400 Regulatory Class: II (two) Product Code: 73 CCK Dear Ms. Saenz: This letter corrects our substantially equivalent letter of September 10, 1996, regarding the Double Lumen Oxygen Delivery Gas Sampling Nasal Cannula. Our letter identified the product code as 73 CAT. This is in error; the correct product code is 73 CCK as indicated above. We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval) it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General (QS) regulation (21 CFR Part 820) and that, through periodic QS inspections, FDA will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory {3} Page 2 - Ms. Sheryl Saenz action. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the *Federal Register*. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. This letter will allow you to continue marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for *in vitro* diagnostic devices), please contact the Office of Compliance at (301) 594-4648.
