Participant Flow

All patients included in the study were adults (\>18 years) who presented with acute respiratory failure and ARDS, had positive reverse transcriptase-polymerase chain reaction (RT-PCR) test results for SARS-CoV-2 virus and presented with clinical and/or radiological signs of COVID-19 pneumonia upon hospital admission. Exclusion criteria were represented by any of the following: Pregnancy, patients with suspected or confirmed pulmonary embolisms and patients with terminal disease.

Treatment Arm
In the treatment arm, Therapeutic plasma exchange will be conducted in the first 24 hours after being admitted into the intensive care unit, after which convalescent plasma from donors that have had COVID-19 will be transfused Therapeutic plasma exchange: The intervention is a combination between the procedure of Therapeutic plasma exchange and biological transfusion of convalescent plasma from donors that have have COVID-19
Control Arm
In the control arm, patients will receive standard COVID-19 treatment

Data regarding adverse event collection was obtained by the continuous monitoring of vital signs specific for the intensive care unit. During the treatment proposed in the intervention arm of this trial, a physician was supervising the vital signs of the patient to immediately stop the treatment in the event of an adverse event.
