[A system for "intermitten mandatory ventilation" (IMV) using the engström respspirators ER 200/300 (author's transl)].

At low financial and material costs conventional Engström-respirators (Types ER 200, 300) can be converted to make Intermittent Mandatory Ventilation (IMV) possible. These so converted respirators were examined when a group of patients in a surgical intensive care unit who had undergone mechanical ventilation for a longer period of time was weaned from the respirator. It could be shown that during the step-by-step weaning of these patients no significant changes appeared in the results of the blood gas analyses, which means that the patients' pulmonary function took over again gradually. Doubtlessly, the convertability of the Engström-respirator for IMV will help promote the weaning of patients with respiratory complications by this method.
