Abstract

A system for assisted breathing has a ventilator delivers a breathing gas to a living creature in order to facilitate, support and/or control the breathing of the living creature. The respiratory musculature is weakened during treatment with a ventilator, long-term treatment in particular, and this results in longer treatment times, especially weaning times. Accordingly, a stimulation apparatus, devised for connection to the living creature, is incorporated into the system for assisted breathing in order to stimulate the respiratory nervous system and/or respiratory musculature of the living creature. Weakening of the respiratory musculature can be reduced by the stimulation apparatus emitting a stimulation signal at specific intervals.
