UArizona Invention May Help COVID-19 Patients Breathe Easier
Tech Launch Arizona

Researchers at the University of Arizona College of Medicine – Tucson have invented a new respiratory-assist device, or RAD, that provides fast, safe relief to those who experience difficulty breathing. Dr. Sairam Parthasarathy, professor of medicine and chief of the UArizona Division of Pulmonary, Allergy, Critical Care and Sleep Medicine, and Dr. Marvin Slepian, Regents Professor of Medicine and director of the UArizona Center for Accelerated Biomedical Innovation and BIO5 faculty, created the new device: a small-scale, low-pressure heliox rebreathing system that simultaneously removes carbon dioxide while appropriately adjusting for humidity as it recirculates gasses in a closed system. To battle one of the major complications of COVID-19, inflammation in the respiratory tract and lungs that can lead to life-threatening pneumonia, the fast and safe application of a RAD can make the difference between life and death.
