## Indications for use
The Spacelabs Medical 90519 Anesthesia Delivery System provides intermittent or continuous gas inhalation for adults and children (neonatal and pediatric). It allows the administration of operator selected gas mixtures of oxygen, nitrous oxide and air with any of the anesthetic agents: Halothane, Isoflurane, Enflurane, or Sevoflurane. It provides safe and accurate gas flows to maintain patient respiration during anesthesia, and incorporates 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 anesthesia machine. It is recommended for use only by trained physicians, in the operating room or similar surgical environments.
