Pegasus Research Corporation was formed by Ken Miller (the inventor of the Concha Humidification System and the Vapor Phase Humidification System) as a design and consulting firm to develop ideas into products for Respiratory Care. In its infancy Pegasus was mostly design and consulting firm until one day Ken decided to put together a team and go into manufacturing himself.

Since then many successful respiratory product lines have been developed and sold through Pegasus. The most successful was the Thera-Mist line of Nebulizer and Humdification Systems consisting of multiple heater, nebulizer and humidifier configurations. This line of products was sold in late 2003 to DHD Healthcare of NY.

Pegasus now offers another line of humidification systems as well as low pressure alarm gauges for O2 and N2. Pegasus also manufactures respiratory heaters for DHD Healthcare and Hudson RCI.

Pegasus is ever changing design and operations to best suit the ever changing market.
