Infections 
The Extracorporeal Life Support Organisation (ELSO) approximates the incidence of infection of 13.0% and 17.5% in VA-ECMO and VV-ECMO respectively. The prevalence of infection during ECMO is 10-12%, withStaphylococcus aureus , Candida , Enterobacteriaceaeand Pseudomonas aeruginos a being the most common bloodstream infective organisms. Identifying infected patients is difficult due to their inability to mount a pyrexic response possible due to heat loss from ECMO circuit, and leukocytosis is common due to inflammatory response from ECMO treatment itself. Hence, regular cultures could be done if an infection is suspected, especially with prolonged ECMO use.
