The concept of an anesthetic machine
Modern anesthetic machine requires stable anesthetic gas to be released from the compressed gas bottle or accurate concentration of anesthetic vapor to be released from the anesthetic evaporator. At the same time, adequate oxygen supply, complete absorption of carbon dioxide, small void cavity volume and low respiratory impedance should be ensured. In addition, reliable safety devices are needed to prevent human or mechanical failures from harming patients.
Classification of general anesthesia:
a) Inhalation anesthesia
b) Intravenous anesthesia
c) Compound anesthesia
The ideal general anesthesia must have four elements without seriously interfering with the physiological function of the body: complete analgesia, loss of consciousness, muscle relaxation, and inhibition of nerve reflex.
♦Inhalation anesthesia
Inhalation anesthesia is the volatile anesthetic vapor or gas anesthetic inhaled into the lung, through the alveoli into the systemic circulation, in the central nervous system to play the role of general anesthesia.
Inhaled anesthetics are metabolized in the body and decomposed less. Most of them are excreted from the lungs in prototype, and a small amount are excreted through the metabolism of the liver and kidney. Therefore, inhalation anesthesia is easy to control, safe and effective, and is a commonly used method in clinical anesthesia today, but the cost is high.
♦Intravenous anesthesia
Intravenous anesthesia is the use of liquid anesthetic drugs directly injected into the vein, through the blood into the systemic circulation system, in the central nervous system to play the role of general anesthesia.
Most of the intravenous anesthetics are discharged from the body through liver and kidney metabolism, and are decomposed more. It’s a little more difficult to control because it’s injected directly from an IV. But it’s a very low cost method and it’s a very common method in clinical anesthesia today.
♦Compound anesthesia
As the name suggests, inhalation anesthesia and intravenous anesthesia are combined to take the advantages of both, complement each other, is now the most commonly used method of anesthesia.
Inhalation anesthesia and combined anesthesia are inseparable from anesthesia machine

AMJ-560B3 and AMJ-560B5 are available to choose two kinds of gas from Halothane, Enflurane, Isoflurane, and Sevoflurane, ensuring a successful anesthesia operation. You can choose one of them to satisfy your demand.
