Prognostic Value of PtcO2 in Patients With COVID-19

Five percent of patients with COVID-19 progressed to respiratory failure and required ICU admission, such patients often have abnormal oxygen tolerance. However, there is still a lack of clinical indicators to predict the prognosis and treatment responsiveness of COVID-19.

Inclusion Criteria:Age: 18-80 years, male or female; Patients with COVID-9 pneumonia (typical imaging features of COVID-19 pneumonia) (oxygen saturation ≤ 93% during air or arterial partial pressure of oxygen (PaO2)/oxygen concentration (FiO2) ≤ 300 mmHg at rest)；Exclusion Criteria:Pregnant or lactating women; Patients who refuse to undergo transcutaneous tissue oxygen pressure monitoring; Clinicians believe that patients are not appropriate; Patients undergoing ECMO.
