While high-flow nasal oxygen has been one of the success stories of the COVID-19 pandemic, it is not always enough. Sometimes more invasive mechanical ventilation is required. Tiyese Jeranji spoke to Professor Ross Hofmeyr on what mechanical ventilation entails and the measures his team at Groote Schuur Hospital in Cape Town have employed to successfully manage these critical COVID-19 cases.
Doctors at two of the Western Cape’s most severely impacted COVID-19 hospitals say they have seen positive outcomes from using high-flow nasal oxygen instead of invasive mechanical ventilation. Kathryn Cleary asked doctors at these hospitals to explain how and why this kind of oxygen therapy works so well.
