A Toronto doctor posted a moment of pure joy on Twitter: an intensive care team celebrating a patient no longer needing a tube to help them breathe.

"ICU team @SinaiHealth celebrating an extubation," Dr. Chris Yarnell tweeted. "COVID is tough but we are always happy to have a bit of success for our patients."

An extubation is when a patient's breathing tube can be removed, in this case because the patient can now breathe on his or her own.

Dr. Yarnell credited his colleagues at Sinai Health Foundation for the "dedicated care that led to this moment," saying intensive care is a team effort involving nurses, doctors, respiratory therapists, physiotherapists, social workers, researchers, environmental services workers, porters, unit clerks, managers, pharmacists, "and many others."

"Extubation is exciting because it represents liberation from the life support a patient previously needed, even though it is only one step in a long journey back to health," Dr. Yarnell told CBC Toronto.

"We're happy to share this success with the community because we hope it inspires ongoing commitment to physical distancing and other key elements of prevention."
