Anesthesia machine is an automatic pneumatic device with electronic control which allows for a variety of respiratory support options. The device is designed for inhalation anesthesia, artificial ventilation during anesthesia for adult patients or children.

Anesthesia machine Ather 7 has the following features:
- possibility of performing low flow anesthesia
- monitoring of respiratory parameters, including graphical monitoring
- total number of gases: 3
- mechanical flowmeter unit: two flowmeters for each gas
- protection against hypoxic mixture
- large touch-screen LCD display
- using 2 vaporizers with the possibility of switching off each of the breathing circuit
- pneumatic drive
- modular system of adding additional functions for quick installation

The anaesthetic and respiratory apparatus Ather 7 is designed for general anesthesia and monitoring of patient parameters in the operating room.

Functionally, the anesthesia device consists of a respirator with a gas mixing unit, a block of electronic flowmeters, a patient contour, a system for removing the spent gas mixture, vaporizers of inhaled anesthetics and a control unit with a touch display.

The undoubted advantages of this device include the presence of a large visual touch display, which shows graphical parameters of respiratory monitoring, artificial lung ventilation settings and gas monitoring data. The ventilation parameters are controlled using the display.

When you turn on the anesthesia device, the start screen appears, where you can select the patient's category (adult or child), set his weight, select the ventilator mode, start the operating mode or reset all the default settings.

The main screen with the set and measured parameter values appears when the operating mode is started.

Electronic flowmeters are designed to supply three working gases: oxygen, nitrous oxide, and air. They have a digital indication of the flow value. The fresh gas supply channel corresponding to each flowmeter is designed to work with high-pressure gas lines and is equipped with a pressure gauge, a filter, a check valve and an emergency oxygen supply button. Ather 7 can automatically compensate for leaks, which is important when performing low-flow anesthesia.

The device uses vaporizers of inhaled anesthetics, which are compatible with the lockable «Selectatec» mount. It is possible to run two evaporators work sequentially and use liquid inhalation agents: halothane, isoflurane, sevoflurane.

The respiratory system of the device consists of a respiratory circuit, an absorber and a membrane box. The device allows performing lung ventilation both manually and automatically. During manual ventilation, the inspiratory pressure is regulated by the APL valve, while the pressure is monitored by a pressure gauge installed in the respiratory system. The range of pressure values in the respiratory system for the APL valve is from 2–70 cm of w.c. Switching the operation of the respiratory system from automatic ventilation to manual/spontaneous is carried out by a special lever. The devourer is filled with a carbon dioxide absorber and serves to prevent the recirculation of CO₂ and hypercapnia.

The anaesthetic ventilator is operated by an electronically controlled pneumatic actuator, which allows the use of various modes of lung ventilation. In particular, the following modes are available: volume-controlled mode (VCV), pressure-controlled mode (PCV), intermittent forced ventilation with volume control (vSIMV), intermittent forced ventilation with pressure control (pSIMV), pressure support (PSV), optional spontaneous breathing (SPONT) and pressure-controlled ventilation with volume control (PRVC). All mode settings can be seen on the display, which also provides graphical parameters of a particular ventilation method in real time.

Optionally, the device can be supplied with a receiving unit of the active exhaust gas mixture removal system (AGSS), designed to work with additional negative pressure devices. Its use prevents the air pollution in the operating room.

The Ather 7 device can be equipped with a module for analyzing anesthetic gases. This allows for a quantitative assessment of the composition of the gas-narcotic mixture (CO₂, N₂O, O₂, АА). Control and display of digital values and graphical parameters take place in real time. The identification of the anesthetic is carried out automatically. It is possible to measure the concentration both in the lateral and in the direct flow. The device can be equipped with a capnography module and a module for analyzing the depth of anesthesia.
