#### Device Description

FLOW-i is a high-performance anesthesia system designed to meet the many ventilatory challenges within anesthesia, as well as to provide inhalation anesthesia. It is intended to serve a wide range of patients from neonatal to adult.

FLOW-i is a software-controlled circle system for inhalation anesthesia (Sevoflurane, Desflurane, Isoflurane and/or nitrous oxide).

The most important features that enhance FLOW-i performance compared with a traditional anesthesia system are:

- o a ventilator whose functionality is based on ICU-ventilator technology,
- the volume reflector technology, o
- the electronically controlled injector vaporizers and o
- o the ergonomic design.

#### Ventilator

The available ventilation modes in FLOW-i are manual ventilation, Volume Control, Pressure Control and Pressure Support.

The ventilator comprises electronically controlled so-called gas modules to supply the gas mixture (oxygen and air/nitrous oxide) at a dynamic flow requested for high-performance automatic ventilation, or at a constant fresh gas flow during manual ventilation. The gas modules facilitate precise control of gas flow and pressure during automatic ventilation. There are three gas modules (oxygen, air, nitrous oxide) to deliver fresh gas, and one reflector gas module (oxygen) to drive the rebreathing gas.

Pressure, flow and gas concentrations to and from the patient are monitored and displayed on a graphical user interface on a control panel. Via the graphical user interface the user can set all parameters for the ventilation modes just as in an ICU-ventilator, as well as all gas concentrations, alarm limits etc.

FLOW-i is also equipped to enable the patient to be manually ventilated with oxygen in case the system loses its electrical power (mains and battery backup).

#### Volume reflector

The volume reflector replaces the "bag-in-bottle" used in many traditional circle systems. It has a fixed volume of 1.2 liters and no moving parts and is open at both ends. The exhaled gas mixture from the patient is introduced at one end of the volume reflector. During automatic ventilation, the stored gas mixture in the volume reflector is returned to the patient by applying a flow of oxygen from the reflector gas module to the volume reflector's other end. Owing to the design, there is minimal mixing between the exhaled gas and the oxygen in the volume reflector. The amount of exhaled gas returning to the patient via the CO2 absorber is determined by the ratio between the minute volume and the set fresh gas flow.

The volume reflector enables high ventilation performance. Another advantage is that the system can deliver the requested breathing gas even in case of leakage, e.g. at the tracheal tube. The volume reflector cannot be emptied like a "bag-in-bottle".

#### Vaporizers

The FLOW-i anesthesia delivery system uses a vaporizer with an electronically controlled injector. The gas mixture from the gas modules passes through the vaporizer chamber, where the agent is injected, before the fresh gas is delivered to the breathing circuit. The fresh gas flow varies during the inspiration phase in automatic ventilation. This means that the amount of added anesthetic agent also varies during the breath cycle in order to maintain the intended anesthetic agent concentration in the fresh gas. Changes made in set agent concentrations will be instamaneous. The available setting ranges for the anesthetic agents are: Sevoflurane 0-8%, Desflurane 0-18% and Isoflurane 0-5%.

#### Ergonomic design

FLOW-i has many ergonomic features, e.g. it is available as a height-adjustable workstation. The control panel can be tilted or rotated and is mounted on a movable support arm, while the touch screen on the control panel enables easy access to FLOW-i functions.

#### Indications for Use

The indication for FLOW-i Anesthesia System is administering inhalation anesthesia while controlling the entire ventilation of patients with no ability to breathe, as well as in supporting patients with a limited ability to breathe. The system is intended for use on neonatal to adult patient populations. The system is intended for use in hospital environments, except MRI environment, by healthcare professionals trained in inhalation anesthesia administration.

### Comparison of Technological Characteristics to Predicate Devices

#### Comparison of Intended Use

The intended use for the subject device and the predicate devices KION K024213 and Aisys K090233 is in all essentials the same. The devices are all intended for delivery of inhalation anesthesia for the patient ranges from neonatal to adult and shall be used by healthcare professionals trained in the administration of anesthesia in hospital environments. None of the devices is intended to be used during transport or in a MRI environment.

#### Comparison of Technology Used

Summary of technological characteristics of the subject device and the predicate devices: In most respects the subject device uses the same (or very similar) technology as the predicate device KION K024213, but with modern components.

The modifications are essentially as follows:

- 1. The mechanical vaporizers from KION K024213 are replaced with electronic vaporizers.
- 2. The bag-in-bottle is replaced with a volume reflector.
- 3. The flow transducer technology is re-used from the predicate device SERVO-i K073179
- 4. The touchscreen technology is re-used from the predicate device SERVO-i K073179.

The reasons for the modifications are:

- 1. The mechanical vaporizers are replaced with electronic vaporizers to facilitate a more dynamic fresh gas flow, thereby enabling better ventilation performance and faster response to changes of fresh gas settings, i.e. flow and concentrations.
- 2. The bag-in-bottle is replaced with a volume reflector in order to improve ventilation ~… performance.
- 3. The new flow transducer is introduced to improve expiratory measurement accuracy.
- 4. The touchscreen is introduced to improve the usability aspects.

#### Conclusion

Maquet believes that the FLOW-i is substantially equivalent to the two predicate anesthesia machines (KION K024213 and AISYS K090233) regarding intended use of the devices, the indications for use and the fundamental technology of the devices. Maquet has conducted the necessary verification and validation activities to demonstrate that the design outputs of the subject device meet the design input requirements. Maquet has concluded that FLOW-i is substantially equivalent to the two predicate devices.
