Draeger Perseus A500 Anesthesia Machine Recall: Risk of Patient Hypoxia
Draeger Medical recalls Perseus A500 anesthesia machines due to potential risk of delivering 100% nitrous oxide, which could cause patient hypoxia and death. Affected units have specific model numbers and were sold for medical use.
The Draeger anesthesia device may be able to dose 100% N2O. In the event of a fault, the S-ORC module would not prevent setting an N2O flow that would result in a hypoxic mixture from being dosed to the patient. Potential adverse outcomes include death of the patient.

Perseus A500 Anesthesia Machine; Cat. no. MK06000 Product V Product Usage: Intended for use in anesthetizing adults, children, and neonates and can be used for automatic and manual ventilation, pressuresupported spontaneous breathing, and spontaneous breathing. Perseus is equipped with airway monitoring, gas measurement and device monitoring, O2 insufflation, and an anesthetic gas receiving system. Anesthesia is achieved through a mixture of pure oxygen and Air (medical compressed air) or pure oxygen and nitrous oxide, with the addition of volatile anesthetic agents. Ventilation is accomplished on the patient through a laryngeal mask airway, a full-face mask, or an endotracheal tube. The integrated breathing system can be used with partial rebreathing (low-flow or minimum-flow). A non-rebreathing system such as the Kuhn or Medec Water System may be used at the external fresh-gas outlet (optional). Perseus is specified for inhalational anesthesia and/or patient ventilation in accordance with the intended use during surgical or diagnostic interventions.; ASKM-0197 ASKN-0006 ASKN-0007 ASKN-0008 ASKN-0009 ASKN-0013 ASKN-0014 ASKN-0015 ASKN-0021 ASKN-0026 ASKN-0027 ASKN-0028 ASKN-0029 ASKN-0030 ASKN-0031 ASKN-0034 ASKN-0035 ASKN-0036 ASKN-0037 ASKN-0038 ASKN-0039 ASKN-0040 ASKN-0042 ASKN-0045 ASKN-0046 ASKN-0048 ASKN-0049 ASKN-0050 ASKN-0053 ASKN-0054 ASKN-0055 ASLA-0009 ASLA-0010
