## 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.
