In recent years numerous articles have been published on the subject of bacterial contamination of anaesthesia apparatus and lung ventilators, possibly endangering the patient. The conclusions can be divided into three groups:
  1. 1.

    A contamination of lung ventilators when common precautionary disinfection and sterilization measures are observed is unlikely.

  2. 2.

    A contamination of lung ventilators may occur, but it is not expected that this will lead to a loading with germs of the air inhaled by the patient.

  3. 3.

    Contamination of lung ventilators and contamination of the inhaled air cannot be excluded if no additional protective measures are taken.
