No
The summary does not mention AI, ML, or related terms, and the device description focuses on standard anesthesia system functionalities and monitoring.
Yes
The A7 Anesthesia System administers general inhalation anesthetic and maintains patient ventilation, both of which are therapeutic interventions.
No
The A7 Anesthesia System is described as a device used to administer anesthesia and maintain a patient's ventilation. While it incorporates monitoring of gas concentrations (O2, CO2, N2O, and various anesthetic agents), this monitoring is for the purpose of controlling the anesthetic delivery and ventilation, not for diagnosing a medical condition. Its primary function is therapeutic/supportive rather than diagnostic.
No
The device description clearly states it is a "continuous flow inhalation gas anesthesia system that delivers anesthetic vapor and provides for automatic and manual modes of ventilation," and mentions hardware components like "02, CO2, N2O and Agent concentration monitoring." The performance studies also include testing of various hardware modules (AG Module, Fresh Flow Optimizer, etc.) and compliance with hardware-related standards (AAMI / ANSI ES60601-1, IEC 60601-1-2, ISO 80601-2-13, etc.). This indicates it is a hardware device with integrated software, not a software-only medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is used to "administer to a patient... a general inhalation anesthetic and to maintain a patient's ventilation." This describes a device used on a patient for treatment and life support, not a device used to examine specimens from a patient to provide diagnostic information.
- Device Description: The description focuses on the delivery of anesthetic gases, ventilation modes, and monitoring of gases within the system and patient's breathing circuit. It does not mention analyzing biological samples like blood, urine, or tissue.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological specimens.
- Providing diagnostic information about a patient's health status.
- Using reagents or assays.
- Measuring analytes in biological fluids.
The A7 Anesthesia System is a medical device used for anesthesia delivery and ventilation, which falls under a different regulatory category than In Vitro Diagnostics.

The functional and system level testing showed that the device continues to meet specifications and the performance of the device is equivalent to the predicate.
Substantial Equivalence:
Comparison of Indications:
Both the predicate device and the subject A7 Anesthesia System are gas anesthesia machine used to administer to a patient, continuously or intermittently, a general inhalation anesthetic and to maintain a patient's ventilation. The indications for use of the subject device (A7 Anesthesia System) have been modified to add the definition of the pediatric population subgroup. All of the pediatric population subgroup was cleared in the predicate device A7 Anesthesia System (K151954). In conclusion, the minor changes to the indications for use do not change the intended use of the A7 Anesthesia System.
