Anesthesia Machine AR-325 ARI

Anesthesia Machine AR-325 ARI This Anesthesia Machine AR-325 ARI is a medical device used to generate and mix a fresh gas flow of medical gases and inhalational anaesthetic agents for the purpose of inducing and maintaining anaesthesia. It is used to deliver general anesthesia to patients as they undergo a medical procedure. The most commonly used device is the continuous-flow anesthetic machine, which provides a steady flow of air containing a regulated supply of gas. Modern instruments often include monitors and touch-screen displays that provide data on heart rate and oxygen saturation level.

The basic anesthetic delivery system consists of a source of oxygen (O2), an O2 flowmeter, a precision vaporizer, which produces a vapor from a volatile liquid anesthetic, a patient breathing circuit (tubing, connectors and valves), and a scavenging device that removes any excess anesthetic gases. This is critical, since room pollution with anesthetic gases may lead to health problems in animals as well as in humans.

During delivery of gas anesthesia to the patient, O2 flows through the vaporizer and picks up the anesthetic vapors. The O2-anesthetic mix then flows through the breathing circuit and into the patient's lungs, usually by spontaneous ventilation (respiration). Occasionally, it is necessary to use assisted ventilation, especially when opening the chest (thoracic) cavity. Assisted ventilation is accomplished by use of a ventilator or respirator.
