Inogen

Inogen’s mission to improve the quality of life of supplemental oxygen users began in 2001 when Mae, a beloved Grandmother, was prescribed oxygen therapy.

Inogen was founded based on our conviction that oxygen therapy technology was not keeping pace with the desired lifestyles of patients who depended on it to live longer, more fulfilling lives.  We estimate that more than 2.5 million patients in the United States and more than 4.5 million patients worldwide use oxygen therapy.
