{6}------------------------------------------------

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.
