COLLINGWOOD, ONT. Health care teams in South Georgian Bay use a new monitoring program to keep close tabs on high-risk COVID-19 patients who have gone home. The program is a cooperative effort between the Collingwood General and Marine Hospital, the Georgian Bay Family Health Team and the London Health Sciences Centre to prevent the dangers of silent hypoxia in patients who tested positive for the virus. Silent hypoxia can occur when a patient s oxygen levels fall dangerously low. If not cared for, it can cause serious health complications, including respiratory failure. Patients with COVID-19 may only have mild symptoms when they are first diagnosed, but things can progress quickly, especially from day five to 10 days after the onset of symptoms, said Dr. Mark Quigg, Family Physician, Georgian Bay Family Health Team.
