These anaesthesia machines are apparatus for providing continuous gas inhalation for adults and children (neonatal and paediatric). They allow the administration of operator selected gas mixtures of oxygen, nitrous oxide and air with any of the anaesthetic agents; Halothane, Isoflurane, Enflurane, or Sevoflurane. They provide safe and accurate gas flows to maintain patient respiration during anaesthesia, and incorporate a ventilator, an oxygen monitor and a respiratory monitor. The ventilator provides the necessary power, as air or oxygen, to generate volumes and pressures in the ventilating system to ventilate a patient connected to the anaesthesia machine. They are recommended for use only by trained physicians, in the operating room or similar surgical environments.
