A leading doctor on a Covid ward has revealed how he saw a healthy-looking patient sitting up preparing to call a loved one, only to find him dead 15 minutes later.
Professor Hugh Montgomery, who works at London s Whittington Hospital, said the patient had looked pretty good when he left him to ring his wife.
But the top doctor, an intensive care specialist who has published over 450 scientific articles, said when he returned 15 minutes later he found that the man had died.
The man had seemingly passed away having been a victim of happy (or silent) hypoxia - a Covid-related phenomenon which means patients appear fine despite having dangerously low oxygen levels.
