1. A substance delivery apparatus for use with a system for supplying breathable gas pressurized above atmospheric pressure to a human or animal, the apparatus including:
- means for continuously measuring the pressure of a supplied breathable gas;
means for detecting inhalation by the human or animal; and
means for delivering a substance to the human or animal during an inhalation at a pressure that exceeds the measured pressure of a supplied pressure of the breathable gas by a predetermined pressure difference.
