Canada's hospitals deploy artificial lungs, scramble for staff as COVID-19 hits younger patients

TORONTO - Younger Canadians are bearing the brunt of the nation's latest COVID-19 surge, creating growing demand for artificial lungs and a struggle to maintain staffing in critical care units as hospitals make last-ditch efforts to save patients.

Treatment with artificial lungs, known as extracorporeal membrane oxygenation, or ECMO, is much more likely to be deployed for patients under age 65, explained Marcelo Cypel, surgical director for the extracorporeal life support program at Toronto's University Health Network (UHN). Last week, there were a record 19 ECMO patients at UHN, 17 of them with severe COVID-19. When the sickest COVID-19 patients' lungs fill with fluid and mechanical ventilators can no longer do the job, artificial lungs can save lives.
