Anesthesia-ventilation machines

During surgery, an anesthesia machine delivers oxygen and air to the patient, plus nitrous oxide, in a set ratio, adds inhaled anesthetic vapor to the mix and ventilates the lungs while the patient is asleep. The Finer catalog has anesthesia machines for adults and children, models with mechanical or electronic gas dosing, an MRI-compatible version, and anesthesia carts. The workstations are made by Siare and Chenwei Medical as well as Medec International, and the carts by Tiscomed.

What is an anesthesia machine used for?

No operating room that gives general anesthesia can work without one, and neither can a delivery suite. The machine handles two jobs at once. The first is an accurate gas mixture with the right anesthetic concentration. The second is ventilating the lungs while the patient does not breathe on their own. Exhaled gas passes through an absorber that removes CO2 and returns to the breathing circuit, so less anesthetic is used at low flow. For anesthesia during a scan there is a separate MRI-compatible version that works even inside the MRI room. Next to the machine, the anesthesiologist also needs a monitor and infusion pumps, plus a cart that keeps everything within reach.

Which anesthesia machines are in the Finer catalog?

The Morpheus line from Siare is the largest. The Morpheus M cart-mounted anesthesia machine has mechanical controls, and the Morpheus E electronic ones. The Morpheus ND anesthesia machine is described as a standalone workstation with a built-in oxygen concentrator. The Morpheus M (MRI) anesthesia machine is made for MRI rooms with 1.5 to 3 T fields. The Caelus anesthesia system with a bag-in-bottle bellows suits all age groups. The Caelus Eco and Caelus Lite are more compact, and the Lite takes the least space. The Astra 3i has mechanical anti-hypoxic protection.

Chenwei Medical is represented by three models. The pediatric CWM-302 has an APL valve. The CWM-201A anesthesia machine has an APL circuit and a vaporizer on a Selectatec mount, while the expert-class CWM-303 has a large touchscreen. To keep everything the anesthesiologist needs within reach, there are the Tiscomed TEC 4520 and TCAC 1310 anesthesia carts.

How do you choose an anesthesia machine?

Start with your patients. If you operate on children, the ventilator must work accurately with small tidal volumes, and the CWM-302 is built for pediatrics. Then the gases: which ones reach the operating room (oxygen, air, nitrous oxide) and where they come from, the pipeline or cylinders. Mechanical flowmeters are simple and familiar to every anesthesiologist. An electronic gas mixer holds the mixture more precisely and suits low-flow anesthesia better; the catalog has both options. The ventilator needs volume-controlled and pressure-controlled modes with support for spontaneous breathing, and some model cards also list servo control.

Monitoring of circuit pressure and volume is always required, along with oxygen concentration. It is often extended with gas analysis (CO2, anesthetic agent) and a patient monitor with depth of anesthesia monitoring. Count vaporizers and consumables separately. Which anesthetics need vaporizers, and on which mount? How much absorbent, how many circuits and filters will a month take? These figures affect the cost of ownership as much as the price of the machine does.

Where to buy an anesthesia machine?

Operating rooms and delivery suites can order an anesthesia machine from Finer Ukraine LLC, which has supplied hospitals with equipment from leading manufacturers since 2015. Finer's doctors and engineers will match a model to your patients and to the gases available in the operating room, then put together the commercial proposal and tender paperwork. They arrange delivery and installation, commission the machine and train the anesthesia team. The price depends on the ventilator class and the gas dosing method, the number of vaporizers, the gas analysis module and the monitor. Some machines have a price in the product card; for the others we calculate a commercial proposal. After surgery, patients in intensive care need ventilators. Operating rooms also use infusion and syringe pumps and patient warming systems. Other equipment is in the Medical equipment section.

FAQ

1. What does an anesthesia machine consist of?

The main parts are the gas supply and mixing block (flowmeters or an electronic mixer), the anesthetic vaporizer, the breathing circuit with a CO2 absorber and an APL valve, the bellows ventilator and a monitor of breathing parameters. All of it is mounted on a cart with a work surface and drawers.

2. How does an anesthesia machine work?

Gases from the pipeline or cylinders are mixed in a set ratio and pass through the vaporizer, where they pick up anesthetic. The ventilator delivers the mixture to the patient's lungs. Exhaled gas is cleared of CO2 in the absorber and returns to the circuit, so less anesthetic is used at low fresh gas flow.

3. Is there an anesthesia machine for MRI?

Yes. The Morpheus M (MRI) from Siare is designed for MRI rooms with 1.5 to 3 T fields. A standard anesthesia machine must not stand next to the scanner: the magnetic field pulls on metal parts and disrupts the electronics.

4. What does the price of an anesthesia machine depend on?

It depends on the ventilator class and the gas dosing method (mechanical or electronic), the number of vaporizers and the gas analysis module. The monitor and MRI compatibility also count. Part of the range is priced on the website, and for the rest we draft a commercial proposal for your operating room configuration.

5. Which anesthesia machine brands are in the catalog?

The anesthesia workstations in the Finer catalog are made by Siare (the Morpheus line), Chenwei Medical (CWM-201A, CWM-302, CWM-303) and Medec International, and the anesthesia carts by Tiscomed. If your facility already works with another brand, tell us which vaporizers and consumables you use and we will take that into account when selecting a model.
