A study of 1,095 patients hospitalized with COVID-19 discovered that two easily measurable signs of health – respiration rate and blood-oxygen saturation – are distinctly predictive of higher mortality. Notably, the authors said, anyone who receives a positive COVID-19 screening test can easily monitor for these two signs at home. This context is lacking in current guidance from the Centers for Disease Control and Prevention, which tells people with COVID-19 to seek medical attention when they experience overt symptoms such as “trouble breathing” and “persistent pain or pressure in the chest” – indications that may be absent even when respiration and blood oxygen have reached dangerous levels, the authors say.
