It is indicated for use on neonates, pediatrics, and adults not under gas anesthesia. The TCM40 Monitoring System is intended for continuous transcutaneous monitoring of oxygen and carbon dioxide partial pressures as well as of oxygen saturation of arterial hemoglobin and pulse rate. It is indicated for use on neonates, pediatrics, and adults not under gas anesthesia. ## Device Story TCM4/40 Monitoring Systems consist of a monitor unit, combined oxygen/carbon dioxide interface module, electrode assembly, and (for TCM40) an oxygen saturation/pulse module. Device inputs include transcutaneous gas signals and pulse oximetry data. The system processes these inputs to provide continuous real-time monitoring of pO2, pCO2, SpO2, and pulse rate. Used in clinical settings by healthcare providers to monitor patient physiological status. Output is displayed on a touch screen, allowing clinicians to assess patient respiratory and circulatory health. Benefits include non-invasive, continuous monitoring of gas exchange and oxygenation status, aiding in clinical decision-making for patients not under gas anesthesia. ## Clinical Evidence No clinical data. Safety and performance were established through bench testing and compliance with consensus standards including IEC-60601-1, IEC-60601-1-2, IEC-60601-2-23, IEC-60601-3-1, EN-865, and IEC-60601-1-8. ## Technological Characteristics Monitor unit includes cabinet, touch screen, electronic controls, power supply, and battery. Uses combined tcpO2/tcpCO2 electrodes and pulse/SpO2 sensors. Connectivity includes integrated monitoring unit. Safety standards: IEC-60601-1, IEC-60601-1-2, IEC-60601-2-23, IEC-60601-3-1, EN-865, IEC-60601-1-8. ## Regulatory Identification A cutaneous carbon dioxide (PcCO2) monitor is a noninvasive heated sensor and a pH-sensitive glass electrode placed on a patient's skin, which is intended to monitor relative changes in a hemodynamically stable patient's cutaneous carbon dioxide tension as an adjunct to arterial carbon dioxide tension measurement. ## Special Controls *Classification.* Class II (special controls). The special control for this device 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. ## Predicate Devices - TCM400 Monitoring System - TCM3 Monitoring System - OxiMAX N-550 Pulse Oximetry System - TOSCA PCO2, SpO2 and Pulse Rate Monitoring System - Perimed Transcutaneous PO2 and PCO2 Monitor (PF5040) - MicroGas 7650 Transcutaneous Monitor - Siemens Transcutaneous TpO2/CO2 Gas Module ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The combined tcp02/tcpCO2 electrode is identical to the electrode used in Radiometer's previous generation TCM3 Monitoring System. The pulse/SpO2 sensors are identical to the sensors used with Puritan Nellcor Bennett's OxiMAX N-550 Pulse Oximetry System. ## Safety and performance evaluation studies In order to ensure TCM4/40 Monitoring Systems is safe and effective for its intended use, it has been designed and tested to the requirements of the following standards: - . IEC-60601-1:1988 Medical electrical equipment - Part 1: General requirements for safety - IEC-60601-1-2:2001 . Medical Electrical Equipment - Part 1-2: General Requirements for Safety Collateral Standard: Electromagnetic Compatibility - Requirements and Tests - IEC-60601-2-23:1999 . Medical electrical equipment - Part 2-23: Particular reguirements for the safety, including essential performance, of transcutaneous partial pressure monitoring equipment - IEC-60601-3-1:1996 . Medical Electrical Equipment Part 3-1: Essential performance requirements for transcutaneous oxygen and carbon dioxide partial pressure monitoring equipment - EN-865:1997 . Pulse oximeters - Particular requirements . IEC-60601-1-8:2003 Medical electrical equipment - Part 1-8: General requirements for safety Collateral standard: General requirements, tests and quidance for alarm systems in medical electrical equipment and medical electrical systems Based upon the extensive use of consensus standards covering all aspects of safety and performance, no clinical evaluation was deemed necessary to assess the product performance levels. ## Conclusions from safety and performance evaluation studies Compliance with the requirements in the above-named safety and performance standards demonstrates that the TCM4/40 Monitoring Systems are state-of-the-art transcutaneous oxygen/carbon dioxide monitors and pulse oximeters that have the necessary safety mechanisms and performs up to the requirements of the relevant international consensus standards. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the seal of the U.S. Department of Health & Human Services.
