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 device is described as an "Anesthesia System" used to "administer to a patient... a general inhalation anesthetic and to maintain a patient's ventilation," actions that are inherently therapeutic.
No
The A7 Anesthesia System is described as a device that administers anesthesia and maintains ventilation, and monitors gas concentrations. Its primary function is therapeutic/supportive (anesthesia delivery and ventilation assistance) rather than diagnosing a condition.
No
The device description clearly states it is a "continuous flow inhalation gas anesthesia system" consisting of a "main unit" and a "detachable breathing system," indicating it is a hardware device with integrated software, not a software-only device. The performance testing also references standards for electrical and mechanical safety (ANSI/AAMI ES60601-1, IEC 60601-1-2, IEC 60601-2-13), further confirming it is a hardware system.
Based on the provided information, the A7 Anesthesia System is not an IVD (In Vitro Diagnostic) device.
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 for testing samples from a patient outside the body.
- Device Description: The description details a system for delivering anesthetic gases and providing ventilation. While it includes monitoring of gases (O2, CO2, N2O, Agent concentration), this monitoring is part of the overall system for managing the patient's respiratory and anesthetic state in vivo, not for diagnostic testing of biological samples.
- Lack of IVD Characteristics: The description does not mention any components or functions related to collecting, preparing, or analyzing biological samples (like blood, urine, tissue, etc.) for diagnostic purposes.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. The A7 Anesthesia System's function is entirely focused on direct patient care and intervention.

Substantial Equivalence:
The A7 that is the subject of this 510(k) submission has been modified from the A7 that was cleared in K142552 to include the Fresh Gas Flow Optimizer feature. The Fresh Gas Flow Optimizer displays a recommended value for fresh gas to assist the clinician in determining a value that will meet the needs of the patient. The predicate device as cleared by FDA did not provide this feature. This feature does not change the fresh gas flow setting nor does it supply an alarm if the user does not follow the recommended fresh gas flow setting.
A technical comparison of the subject device to the primary predicate device as cleared in K142552 is provided in the table below.

Substantial Equivalence Conclusion
The subject A7 Anesthesia System and the primary predicate are both gas anesthesia machines used to administer to a patient, continuously or intermittently, a general inhalation anesthetic and to maintain a patient's ventilation. These systems may be used in adult and pediatric populations. Both of the devices are prescription use, and are not suitable for use in an MRI environment.
Based on the technical comparison, the identical indications for use and the complete system level testing, the modifications to the A7 Anesthesia System do not raise different questions of safety and effectiveness and can be found substantially equivalent to the predicate device cleared in K142552.
