What are the different types of anesthesia machines?by Anisha Patil HPD
An anesthetic machine or anesthesia machine is a medical tool used to produce and mix a fresh gas flow of medical air and inhalational anesthetic agents for the drive of encouraging and maintaining anesthesia. The machine made by Anesthesia Machine Manufacturers is normally used together with a mechanical ventilator, panting system, suction equipment, and patient monitoring devices; strictly talking, the term "anesthetic machine" denotes only the constituent which produces the gas flow, but modern machines typically assimilate all these plans into one shared freestanding unit, which is colloquially denoted to as the "anesthetic machine" for the sake of ease. In the industrialized world, the most recurrent kind in use is the continuous-flow anesthetic machine or "Boyle's machine", which is intended to offer an exact supply of medical gases varied with accurate attention of anesthetic vapor and to transport this unceasingly to the patient at a safe pressure and flow. This is separate from intermittent-flow anesthetic machines, which offer gas flow only on request when activated by the patient's own inspiration.
The kinds of Modern Anesthesia Machines are as shadows:
(1) Air anesthesia machine
The air anesthesia apparatus is semi-open anesthesia expedient. It mostly contains a liquid medicine cistern, an ether variable switch, portable bellows, and a suction and exhalation one-way valve and a bellows. The machine is lightly appropriate and can straight use air and oxygen as a carrier vapor to support breathing and control breathing to meet various medical requirements.
The employed principle is that the patient attaches the air anesthesia apparatus to the closed mask or the tracheal tube after finishing the anesthesia induction. When gasping, the anesthetic blend enters the patient through the open inspiratory flap; when respired, the expiratory flap opens, and the inspiratory flap finales, ejecting the exhaled gas. Portable bellows can be used when supporting or controlling breathing. Press down during breathing and pull up when exhaling to ensure satisfactory ventilation. At the same time, rendering to actual needs, regulates the ether switch to maintain a stable anesthesia level.
The inadequacy of this device is that the absorption of ether is low, and it can only be used as anesthetic upkeep, and the ingesting of ether is large, which is likely to cause environmental pollution.
(2) DC anesthesia machine
The direct current anesthesia appliance supplied by Anesthesia Machine Suppliers in India contains high-pressure oxygen, pressure reducer, flow meter, and anesthetic fluid evaporator. The expedient can only deliver oxygen and regulate the concentration of anesthetic gas to be inhaled. There must be other plans in sequence with the output site for anesthesia.
(3) Shut Anesthesia Machine
The anesthesia machine supplies the patient with a low-flow anesthetic mixture and a one-way action through the outgassing flap (door). The respired gas is re-used through the exhalation tab into the CO2 absorber. Its edifice is mainly collected from an oxygen source and nitrous oxide device, gas flow meter, evaporator, CO2 absorber; one-way valve, breathing tube, outgassing valve, storage airbag, and so on.
Modern anesthesia apparatuses are also armed with ventilator airway pressure, expiratory flow, end-tidal CO2 absorption, breathing anesthetic concentration, oxygen concentration monitor, hypoxic fear, and hypoxic-nitrous oxide automatic protection device.
