Abstract

A respirator system with both assisted and spontaneous breathing modes. A control circuit responds to the patient's breathing pattern to alternate the system between the two modes in accordance with a predetermined alternation pattern. The control circuit is adjustable, enabling the frequency of assisted breaths to be gradually reduced so that the patient can be weaned away from the respirator and safely resume normal breathing under his own power. The invention also includes the operating method contemplated for such a system.
