Brief Summary
Clinical reasoning and recent data suggest that early use of venovenous extracorporeal membrane oxygenation in refractory respiratory failure may confer a survival advantage. This retrospective matched study will assess whether patients who received VV ECMO at less severe hypoxaemia had differing outcomes to those who received ECMO with very severe hypoxaemia.

Secondary Outcomes (1)
Duration of ECMO treatment
Up to 90 days.
Study Arms (2)
'Less severe hypoxaemia'
PaO2/FiO2 ratio \> 68 mmHg (9.1kPa) at decision-to-cannulate

Eligibility Criteria
This is a prespecified secondary analysis of the UK ECMO registry. Inclusion criteria are ultimately at the discretion of each recruiting centre, but includes adult patients with potentially reversible acute respiratory failure without absolute contraindications to ECMO therapy.
You may qualify if:
- Patients included in the UK ECMO registry (see previous registration; NCT number awaited; protocol ECMO-001)
- Patients with VV ECMO
You may not qualify if:
- Patients with inadequate or missing data for creation of propensity score models.
