What are the parts of an anesthesia machine?
The most widely used anesthesia machine anesthesia machine is a continuous flow. These machines regular medical gas mixture such as oxygen and nitrous oxide with a precise dosage of anesthetic gas. Modern versions also have additional monitoring of vital signs of patient equipment. In general, the machine is a complex set of parts, each designed to perform a very specific function. Function
The machine is connected to the outlets on the hospital wall, providing oxygen, air and nitrous oxide. Nitrous oxide is an excellent vehicle for stronger gaseous anesthetics. The gas enters the machine at a pressure of about 60 PSI. The ratio of nitrous oxide to oxygen put out by the anesthetic machine is usually from 2 to 1.
Devices called vaporizers convert the anesthetic agents and the steam is injected into the air supply outlet. This entry of air is mechanically pumped to the patient using a device called a fan. The fan is connected to a face mask via hoses called breathing circuits. The face mask forms a seal around the patient's face to ensure that all gases from reaching the patient and not escape into the air, where they can affect medical staff. Controls
anesthetist has precise control over the mixture in order to assure that the patient stays properly sedated and anesthetized during an operation. It can monitor vital signs and adjust the mix in real time using regulators to independently adjust the flow of oxygen and nitrous oxide. Controls on separate vaporizers allow the expert to increase or decrease the amount of each anesthetic agent that makes the final mixture.
Redundancy
There are backup cylinders on the machine, if there is a fault with the hospital's supply lines. While the machine is in use cylinders are connected with the regulator set at around 45 PSI. Once the main lines are set at a higher pressure, the appliance draws gas from them while they are working properly. If the supply of the main lines is weakened or completely cut the reserve cylinder gas supply without interruptions in supply of the patient.
Safety Features
The patient waking in the middle of an operation, or suddenly become sensitive to pain, can be disastrous. For this reason, there are various safety mechanisms in place in modern anesthesia apparatus.
Since high pressure gas may cause damage to the machine, or worse, the patient, all lines of input gas contain pop-off valves. Pop-off valves are specialized valves that vent the gas pressure reaches dangerous levels.
The medical staff being exposed to anesthetic while performing surgery may spell disaster. Manufacturers are aware of this, then, beyond the seal formed by the face mask of a system of collection and disposal has expired so they are not in the operating room gases.
Other types
In addition to the continuous flow of units used in hospitals, other anesthesia machines used for specialized purposes. One such machine is used on the battlefield where surgeons may have to perform emergency surgery. These portable machines are self-contained, carrying their own oxygen and nitrous oxide tanks. Portable machines do not have a bit of sophistication of its bigger brothers. They have less backup systems in place and lack of cleaning systems.
