Five percent of patients with COVID-19 progressed to respiratory failure and required ICUadmission, such patients often have abnormal oxygen tolerance. However, there is still alack of clinical indicators to predict the prognosis and treatment responsiveness ofCOVID-19.
Five percent of patients with COVID-19 progressed to respiratory failure and required ICU
admission. Attention should be paid to patients over 65 years of age who have severe
underlying diseases (cancer, respiratory diseases, cardiovascular and cerebrovascular
diseases, chronic renal failure, autoimmune deficiency diseases, etc.) and have not
completed the whole course of vaccine, and such patients often have abnormal oxygen
tolerance, that is, a significant decrease in skin finger pulse oxygen saturation (SpO2)
can occur after daily activities. Basal SpO2 at admission is often associated with
prognosis, but it is difficult to differentiate prognosis from responsiveness to
treatment by changes in SpO2 after oxygen therapy is administered clinically. However,
there is still a lack of clinical indicators to predict the prognosis and treatment
responsiveness of COVID-19.
