We continued to look for further developments that would provide a better life for those who suffered from COPD. Around the beginning of the millennium, companies started developing more advanced methods for oxygen delivery. Scientists began working on machines that used filters -fed by compressors-to create medical oxygen from ambient air. The first machines were primitive with not much battery life, but we immediately recognized the potential of this emerging technology as something that could completely transform an oxygen patient’s life from sedentary and burdensome, to free and independent. It was then that we dedicated ourselves to becoming the largest distributor in the world of oxygen concentrators. We believed these products could work miracles in the lives of our patients. We were right!
