Our Experiences in the Use of Ozone Therapy in the Elderly M. Casas, B. Conde, F. Ramos. Camilo Cienfuegos Provincial Hospital, Sancti Spiritus, Cuba. During five years (1991-1995) we have used ozone therapy in the treatment of different diseases that are present in the elderly, for example upper and lower respiratory infections, arthrosis, pneumonia, immunodeficiency. A statistical analysis showed improvement in more than 80 % of the treated patients. No side- effects or intolerance was present among the patients treated with ozone. It is concluded that ozone therapy is an important therapeutic option to be considered in geriatric patients. Source: 2nd International Symposium on Ozone Applications Havana, Cuba - Mach 24-26, 1997.
