It is an essential device for medical and hospital centers, they are used to supply anesthetic gases to the patient and control their breathing during a surgical process, its process consists of mixing medical gases such as air, oxygen, or an air mixture, with anesthetic gases: nitrous oxide xenon and anesthetic agents by inhalation or volatile halogenated agents, in addition to allowing spontaneous or controlled, manual or mechanical ventilation.
The quantities and proportions of the gases supplied by the equipment, as well as the flow of these mixtures, are adjusted by the flow meter. As a safety measure, it has a control valve that prevents the retrograde flow of gases into the atmosphere; The device receives the compressed gas from a supply source and through the flowmeters.
Components of an anesthesia machine.
To handle an anesthesia machine it is essential to know the components that make up the equipment and their function; in this way it will be possible for the user to know how it is used:
- Oxygen Connections: The various supplies of medical air and nitrous oxide, air and oxygen gas joined through a pin index safety system yoke with a Bodok seal.
- Pressure gauges, regulators and pop-off valves: they serve to control gas pressure, protect equipment components and protect the patient from excessive increases.
- Flow meters: to adjust oxygen, air and nitrous oxide.
- Vaporizers: allows you to control the precise dose of volatile anesthetics.
- Monitoring systems and warning failure: allows to monitor the gases supplied and inhaled by the patient.
- High Flow Oxygen Discharge: Provides pure oxygen at 30-75 litres/minute.
Types of anesthesia machines
- High pressure system: backup gas source, safety devices, clinical gas sources.
- Low pressure systems: anti-reflux valve, flow control valves, vaporizers, rapid flow valve.
- Circular system: soda lime receptacle, a Y-shaped container, expiratory and inspiratory corrugated tubes, one-way valves, APL overpressure valve, a bag, a respirator and a gas inlet.
Main characteristics of Anesthesia machines
When choosing an anesthesia machine, you can count on us KALSTEIN, which offers you the possibility of monitoring the patient’s condition, we guarantee full functionality to anesthesiologists and other medical personnel involved in the procedure, in addition to our equipment offering guarantees of innovation, and updating in the operating room area, they also have the main characteristics of this type of equipment:
- Source of dioxygen or gaseous oxygen and a form of CO2 removal.
- A source of fluids or gases for anesthesia.
- An inhalation system made up of: cylinders, yokes, valves, flow meters, pressure gauges and others.
Flowmeters
It is one of the components that is necessary to know by the user; because it will allow them to supply the correct proportions of gases to the patient and it is essential to know for the correct use of anesthesia machines, there are three types:
- Float: it is located in the upper part of the respirators, it is composed of a flow control valve, a flow tube, the float and the indicator scale, all of them connected, and whose function is to show through the scale indicates the amount of flow passing.
- Vane: they have a constant orifice and variable pressure; they have a small round bed with a transparent front face to see the movement of the indicator vane.
- Electronic: it measures the flow by the variation in temperature suffered by the thermal sensor that is located in the center of the gas stream.
Maintenance and fault detection
- Check that the casing and accessories are intact and complete.
- Examine the conditions of the tubes, hoses and their connections, verifying there are no leaks or obstructions.
- Keep the equipment clean, with no signs of liquids or spills.
- Clean the filters and replace them if necessary.
