title: An IMV setup without a compressed air source.
abstract: Intermittent mandatory ventilation (IMV), as described in the literature, utilizes an air-oxygen blender and a compressed air source. When older ventilators are used and in locations in which compressed air sources are unavailable, other arrangements must be made if IMV is to be used. An arrangement is described in which a bird Mark 7 respirator, after the removal of its pneumatic clutch, is inserted into the IMV assembly. Such an arrangement produces wide FIO2 ranges and high flows and obviates the need for an oxygen blender and compressed air source. If a compressed air source is available or if a bird Mark 7 respirator is not available for use, othe arrangements may be more satisfactory.
