During the first two years of the COVID-19 pandemic, oxygen was a lifesaving consumable, but in many remote rural areas of the Eastern Cape, logistical challenges such as poor roads and long distances made distribution difficult. A group of doctors and engineers, however, developed a sustainable lifeline in the form of an oxygen generator at Madwaleni Hospital. Luvuyo Mehlwana reports.
Even in ‘normal’ times a reliable supply of medical oxygen is an essential part of healthcare services, but during COVID-19 surges the need for this life-sustaining gas has spiked to unprecedented levels. Tiyese Jeranji explores the fascinating science and engineering that facilitates this substance’s long journey from a production plant to a person’s lungs.
