# Technology comparison
## Gas management
Similarities between the product and the predicate devices.
Cylinder yokes for PIN index E-cylinders allow the attachment of two O2, one N2O and 1 Air cylinder. The cylinder supply management contains filters at the cylinder gas inlet, check valves for the two O2 cylinder inlets to prevent bleeding of one cylinder, if the other yoke is not used, pressure regulators to reduce cylinder pressure downto the normal operating pressure and Bourdon type cylinder pressure gauges for each cylinder gas supply line.
Pipeline inlets with DISS connectors for O2, N2O, Air, Vac and Evac allow the attachment of central gas supply. Bourdon type pressure gauges indicate the pipeline pressure to the operator. A check valve arrangement for each gas provides the separation of cylinder and pipeline supply line.
The O2 supply line is checked for sufficient pressure level. When the O2 supply pressure drops below the specified minimum pressure level the O2 fail alarm device alarms the operator to the low O2 pressure.
In case the O2 supply pressure drops below the specified N2O-shut-off-O2-pressure-level, the N2O supply is shut off.
A main switch activates the device's gas supply.
Differences between the product and the predicate devices.
In the Anodyne CC patient and device is protected by water traps and particulate filters. In the predicate devices there are no built-in water traps. These are added as accessories.
In the Anodyne CC the O2 fail alarm operates pneumatically, using a pneumatic whistle. In the predicate devices the O2 fail alarm operates with an electrical alarm device delivering an alarm tone.
In the Anodyne CC the gas mix selector enables the operator to select one of four different Freshgas selections.

## Hypoxic guard
Similarities between the product and the predicate devices.
The O2/N2O mixture delivered in the Freshgas is generated from a hypoxic guard system providing a specified minimum percentage of oxygen.
The operator is not able to adjust a mixture below this minimum O2 concentration. A minimum O2 flow is supplied to the Freshgas line, in case gas selections with N2O are made.
The combination of a specified minimum O2 flow and a hypoxic guard system provides an oxygen concentration dependent on the total Freshgas flow.
Between mid and high flows the O2 concentration stays at the minimum level as specified. For lower flowrates the O2 concentration increases up to 100 % when the minimum O2 flow is reached.
Differences between the product and the predicate devices.
The Anodyne CC uses a mechanical hypoxic guard system.
So does the OHMEDA device.
The NAD unit uses a pneumatic system.
## Flowcontrol
Similarities between the product and the predicate devices.
The flowcontrol enables the operator to dose the gas flow precisely by changing the orifice of a valve.
The flowcontrol for each gas is mounted correspondent to the flowmeters.
An independent O2 flush allows a fast delivery of oxygen to the patient.
Differences between the product and the predicate devices.
None.

## Flowmetering
Similarities between the product and the predicate devices.
The flowmeter set consists of two flowmeters for each gas with a fine and a coarse tube. The tubes are cascaded. Due to the overflow from fine to coarse the fine tube shows the specified values for the fine range and the coarse tube, beginning with the end of the fine tube range, shows the coarse range. The flowmeter tube operates with the taper-cone-float system.
Differences between the product and the predicate devices.
None.
## Vaporization
Similarities between the product and the predicate devices.
The vaporizer assembly is able to carry three vaporizers at a time with a safety function to enable only one vaporizer to work at a time.
The NAD device uses Dräger back entry type vaporizers. These back entry type vaporizers are mounted fixed to the vaporizer assembly and are not detachable. An exclusion system enables only one vaporizer to be operated at a time.
The OHMEDA device has a mounting system to carry detachable vaporizers of the Selectatec type. These vaporizers have a standardized mounting system for the gas connectors and the locking mechanism. The mounting system on the device allows only vaporizers to adapt, that have an interlocking mechanism providing only one vaporizer to operate at a time.
The Anodyne CC can be equipped with either system, mentioned above.
Differences between the product and the predicate devices.
None.

## Ventilator
Similarities between the product and the predicate devices.
The ventilator allows manual and controlled mandatory ventilation mode.
The ventilator is a time-cycled-flow-controlled type with pneumatic gas supply and electronic control.
The ventilator allows ventilation of pediatric and adult patients.
The ventilator has an adjustable pressure limiting function and a separate safety pressure limiting valve.
The ventilator provides PEEP capabilities.
The ventilator activity is transferred to the patient gas circuit by a bellows assembly, contained within a cannister with clear plastic housing to view the bellows movement.
Differences between the product and the predicate devices.
The NAD device allows the adjustment of I:E ratio, rate and flow. With these settings the ventilator creates a specific tidal volume as a resulting parameter.
The OHMEDA device allows the adjustment of rate, flow, an tidal volume. The I:E ratio is a dependent variable.
The Anodyne CC combines both systems in a way, that adjustments for I:E ratio, rate and tidal volume are allowed and the flow is a dependent variable.

## Bellows
Similarities between the product and the predicate devices.
The bellows operates in a so called "bag in bottle" principle. A gas flow created by the ventilator powers the bellows housing and pressurizes the bellows inside.
The bellows transfers this activity onto the patient gas circuit, separating the two gas circuits by its membrane.
Differences between the product and the predicate devices.
The OHMEDA device uses bellows with two different sizes to match the different tidal volume ranges for pediatric and adult ventilation.
The NAD device uses only one bellows for both ventilation ranges.
So does the Anodyne CC.
NAD and OHMEDA use a separate ascending bellows assembly.
The Anodyne CC uses a descending one integrated inside the rebreathing circuit.
## Absorber
Similarities between the product and the predicate devices.
An absorber system retaining the patients exhaled CO2 is installed, prepared for two prefill absorber container. The absorber canister allows the CO2 flow to move downstream.
The absorber canister is of transparent material to allow the operator to watch a color indicator inside the absorber material.
Differences between the product and the predicate devices.
The predicate devices have the absorber mounted as a separate component from the basic machine.
On the Anodyne CC the absorber is integrated inside the rebreathing system.

# Rebreathing circuit / Patient module
Similarities between the product and the predicate devices.
The rebreathing circuit is a system to handle the gas going to and coming from the patient, representing the interface between basic gas machine and patient.
Inside the circuit directional valves control inspiratory and expiratory gas flow.
The rebreathing circuit allows the freshgas to flow to the patient with a blender type function between freshgas and rebreathing gas. Rebreathed gas flows to the CO2 absorber to retain the CO2 before it is blended with Freshgas.
A bag is connected to the rebreathing circuit to allow manual mode ventilation with an adjustable pressure limiting valve (APL) enabling the adjustment of the maximum airway pressure.
Differences between the product and the predicate devices.
The predicate devices have the absorber mounted as a separate component to the basic machine. Several connections to the basic machine for bellows, Freshgas and pressure measurement are necessary.
The predicate devices have the ventilator's bellows assembly mounted as a separate component to the basic machine. A connection between rebreathing / absorber system and bellows assembly is necessary.
On the Anodyne CC the absorber and the bellows assembly are integrated inside the rebreathing system. All connections to the basic machine are made inside the rebreathing system's docking station.
To prevent subatmospheric pressure effecting the patient the Anodyne CC allows room air to supply the rebreathing system in case a subatmospheric pressure is detected through an "emergency air intake" valve.
To provide a fast pressure release in case of an accidental overpressure inside the rebreathing circuit the Anodyne CC provides an integrated Pop-off valve function.

## Spirometry measurement
Similarities between the product and the predicate devices.
Flow measurement is performed to get information about the patient's expiratory tidal volume, minute volume and rate. The measured data are displayed to the operator to allow on-line control of ventilation efficiency.
Minimum alarm limits are adjustable to monitor the patient's tidal volume and/or minute volume activities.
Differences between the product and the predicate devices.
The NAD device displays the spirometry information in a separate monitoring display.
The OHMEDA device displays the spirometry data inside the ventilators display.
So does the Anodyne CC.
The predicate devices use separate stand alone spirometry sensors, that need to be mounted either onto the rebreathing circuit (NAD) or inside the expiratory line (OHMEDA).
The Anodyne CC carries the spirometry sensor inside its rebreathing circuit.
## Pressure measurement
Similarities between the product and the predicate devices.
Airway pressure measurement is performed to get information about the patient's airway pressure. Peak and PEEP pressure information is displayed numerically. A Bourdon type pressure gauge allows the operator to watch the pressure-time characteristic of the ventilation. Maximum and minimum pressure limits are adjustable to monitor the patient's airway pressure.
Differences between the product and the predicate devices.
The predicate devices also displays the pressure information in a separate monitoring display.
The Anodyne CC also displays the pressure data inside the ventilators display.

## Oxygen measurement
Similarities between the product and the predicate devices.
Inspiratory oxygen concentration measurement is performed by a fuel cell type sensor mounted inside the inspiratory pathway.
The information is displayed numerically. Maximum and minimum oxygen concentration limits are adjustable to monitor the patient's inspiratory concentration.
Differences between the product and the predicate devices.
The NAD device displays the oxygen concentration information in a separate monitoring display.
The OHMEDA device displays the oxygen concentration data inside the ventilators display.
So does the Anodyne CC.

# Clinical discussion
The HEYER America Anodyne CC anesthesia system is also based on the technology of a product series legally marketed in Europe and manufactured by HEYER Anesthesia, such as:
| Manufacturer | Model | Approval No. | Approval Date |
| --- | --- | --- | --- |
| HEYER Anesthesia | DOGMA® | 09/M-015/94 | 05/11/1994 |
| HEYER Anesthesia | ACCESS® | 09/M-019/95 | 10/25/1995 |
Numerous units of these types are in clinics and hospitals inside Europe being used as anesthetic gas delivery machines.
Compared to the predicate devices these devices have proven over the years to have the same level of safety and efficiency in Europe where the predicate deives are also sold.
# Conclusion
Basing on the technology comparison, the performance comparison and the clinical discussion we can confirm the HEYER America Anodyne CC to be as safe as and as effective as the predicate compared devices.
