You may qualify if:

• Admitted to the hospital
• There is a PCR positive sample for SARS-CoV-2 within the past 21 days. The sample can be a nasal orpharyngeal swab, sputum, tracheal aspirate, bronchoalveolar lavage, or another sample from the patient

• APTT \> 120 seconds, not due to anticoagulant therapy and does not correct with administration of fresh frozen plasma
• Platelet count \< 20 x 109 per L
• Pulmonary bleeding or uncontrolled bleeding
• Pregnant or might be pregnant
• Acute brain injury that may result in long-term disability
• Myopathy, spinal cord injury, or nerve injury or disease with a likely prolonged incapacity to breathe independently e.g. Guillain-Barre syndrome
• Treatment limitations in place, i.e. not for intubation, not for ICU admission
• Death is imminent or inevitable within 24 hours
• Clinician objection
• Refusal of participant (person responsible) consent
