Summary
Brief summary
Patients who are critically ill in intensive care with moderate to severe acute respiratory
infection often require mechanical ventilation. Prolonged ventilation increases the risk of
lung damage and other side effects as a result of long term use of sedation medications.
Extracorporeal membrane oxygenation therapy (ECMO), is a relatively new technology that uses
a pump to remove blood from the body and return it back to the body after adding oxygen and
removing carbon dioxide. ECMO can be used on patients who require mechanical ventilation and
can function without the need for ongoing mechanical ventilation, thus reducing risk of side
effects. Participants will be randomised into either the early ECMO therapy group or will
continue standard treatment involving mechanical ventilation.

This pilot study aims to determine if a phase 3 Randomised Control Trial (RCT) is feasible
for the use of early ECMO therapy to treat patients with Severe Acute Respiratory Infection
(SARI). The success of the study will be determined by the successful recruitment of adult
patients, that there is a difference between ECMO utilisation between groups and that there
are no safety issues.
