For more than a year, Doucette has been caring for COVID-19 patients as a nurse in the intensive care unit at Saskatoon's Royal University Hospital. Doucette says the hospital's ICU is full of patients on ventilators, with doctors, nurses and respiratory therapists doing minute-by-minute care. All patients with COVID-19 are now in isolation wards, and medical personnel must put on full personal protective equipment before stepping inside. Doucette says the ICU ward has become a stressful place, with anxious health-care providers carefully watching COVID-19 cases, looking for a spike in numbers.
