If you need Anesthesia Machines, there are many Anesthesia Machines and other medical equipment and supplies that you can find online. There is also a plethora of veterinary medical equipment to be found with just a click of the mouse. The primary purpose of the anesthetic machine and system is to deliver an inhaled anesthetic to the animal to keep him unconscious through surgery.
A rebreathing bag is an inflatable rubber bag which allows the accumulation of fresh and expired gas during exhalation so that a reservoir of gas is available for the next breath. The bag also acts as a safety device to prevent rapid pressure increases in the system. It can be manually squeezed to bag an animal as needed during surgery to assist breathing. The exhalation hose carries the gases the animal breathed out back to the anesthetic medical equipment.
Rebreathing systems are used for animals weighing over ten pounds. The following diagram shows the parts of a rebreathing system which allows recirculation of exhaled gases to the animal. Each breath contains exhaled gas that has had the carbon dioxide removed and fresh oxygen and anesthetic added.
The vaporizer converts the liquid anesthetic to a gas state and adds controlled amounts of the gas anesthetic to the oxygen that is flowing through the machine.
The oxygen flush valve allows oxygen to flow directly to the animal bypassing the anesthesia. It is used to quickly increase the amount of oxygen and decrease the anesthesia in the system. This is done at the end of the anesthesia or if the animal is at too deep of a plane of anesthesia during the surgery.
A flowmeter allows the anesthetist to determine the rate the oxygen will flow to the animal. The rebreathing system has a Y piece which connects the inhalation hose, endotracheal tube, and exhalation hose. Oxygen source with pressure gauge and is supplied to the animal. It also is the carrier gas that brings the inhaled anesthetic to the pet. The pressure reducing valve decreases the high pressure from the oxygen tank to a usable level. The inhalation valve allows the gases to flow only to the animal and not back to the vaporizer, by way of a one-way valve.
The Endotracheal tube is placed into the animal's trachea to allow the oxygen and gases to be breathed into the lungs. The exhalation valve allows the exhaled gases to flow only into the anesthetic machine, not back to the animal, by way of a one-way valve. The Pop-off valve is a pressure relief valve that allows the release of waste gases and extra pressure from the system into the scavenger hose. The scavenger hose carries waste gases out of the system and out of the building. Any gases that do exit through the pop-off valve pass through the carbon dioxide absorber before returning to the animal. The chemicals in the container remove carbon dioxide from the gases that pass through it. The vaporizer converts the liquid anesthetic to a gas state and adds controlled amounts of the gas anesthetic to the oxygen that is flowing through the machine. The gases exit the vaporizer and go directly into a hose for delivery to the animal. The connecting port connects the inhalation and exhalation hoses to the endotracheal tube. An anesthesia machine is such an important piece of hospital medical equipment, and now you know how it works!
