Intended Use

The Linde Transcutaneous Monitor is intended to measure the partial pressure of oxygen and carbon dioxide that passes through the cutaneous layer of the skin of an infant who is not under gas anesthesia by a sensor attached to the surface of the infant's skin.

Device Description

Detailed description of the device is contained in the MicroGas 7650 Operator's Manual located in Appendix 2 of this document.

AI/ML Overview

The provided document for K991644, the MicroGas 7650 Transcutaneous Monitor, does not include acceptance criteria or a study proving the device meets acceptance criteria.

Instead, the submission states:

  • Clinical and Non-Clinical Tests of Equivalency: "The MicroGas 7650 is exactly the same device as the MicroGas 7650 distributed by Kontron Instruments under PMA P810037. Both devices are manufactured by Linde Medical Sensors AG of Basel, Switzerland. Because there are no differences other than labeling between the Linde MicroGas 7650 and the Kontron MicroGas 7650, no additional clinical or non-clinical tests were performed or submitted in the premarket notification. Refer to PMA number P810037 for this data."

This means that the current K991644 submission obtained clearance based on substantial equivalence to a previously approved device (Kontron MicroGas 7650, PMA P810037) and did not present new performance data for acceptance criteria. To find the information requested, one would need to refer to PMA P810037.

Therefore, I cannot populate the table or answer the subsequent questions based on the provided text for K991644, as this information is explicitly stated to be in a separate, referenced document (PMA P810037).

  9. How ground truth for training set was established: Not applicable/not provided as no new studies were conducted.

§ 868.2500 Cutaneous oxygen (PcO2) monitor.

(a)
Identification. A cutaneous oxygen (PcO2) monitor is a noninvasive, heated sensor (e.g., a Clark-type polargraphic electrode) placed on the patient's skin that is intended to monitor relative changes in the cutaneous oxygen tension.(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 868.9. The special control is FDA's “Class II Special Controls Guidance Document: Cutaneous Carbon Dioxide (PcCO2) and Oxygen (PcO2) Monitors; Guidance for Industry and FDA.” See § 868.1(e) for the availability of this guidance document.
