1. A breathing apparatus for supplying a respiratory gas to a subject, comprising:
- delivery means for supplying respiratory gas to a respirating subject;
sensing means for sensing spontaneous inhalation efforts of said respirating subject; and
control means for controlling said delivery means for causing said delivery means to emit a supportive inspiration pulse, in response to a sensed inhalation effort having a magnitude as sensed by said sensing means, and having an amplitude in inverse relationship to said magnitude of said sensed inhalation effort.
