Description of intervention(s) / exposure
No specific exposure intervention that will be evaluated in this study. It investigates how effective is the intervention (ECCO2R with PrismaLung) that is being used on the patient in reducing the lung injury known to associated with mechanical ventilation.
This study includes patients already receiving ECCO2R with PrismaLung as part of their standard mechanical ventilation treatment,
Driving pressures on the ventilator prior to initiation of PrismaLung will be compared with the driving pressures while the patients are receiving PrismaLung for up to 144 hours.
Arterial blood gasses and cytokine profile will be compared prior to initiation and after initiation of PrismaLung for up to 144 hours. All data will be available from the medical records.

Statistical methods / analysis
Data will be presented as mean and SD of the mean or median and interquartile (25th and 75th percentile) range as appropriate. The primary outcome driving airway pressures will be analysed using linear mixed effects models (PROC MIXED procedure in SAS) fitting main effect for time (24, 48, 72 and 144 hours) with results reported as means and 95% confidence intervals (95% CI). To facilitate specific comparisons time will be treated as a categorical variable. Post-hoc comparisons will be performed to assess changes between time points. All calculated p values will be two tailed and a p < 0.05 will be considered to be statistically significant. Analyses will be performed with SAS software version 9.4 (SAS Institute, Cary, NC, USA).

Summary
Brief summary
Some patients when receiving such mechanical ventilation develop hypercapnia and associated hypercapnic acidosis. Such patients have an increased risk of mortality. While the exact reasons of such increase in mortality is not known, it is recommended to minimise hypercapnia and hypercapnic acidosis during lung protective ventilation. Minimally invasive extracorporeal carbon dioxide removal (ECCO2R) devices are shown to reduce hypercapnia and hypercapnic acidosis. There are several devices that are currently available in the current clinical practice. However the effect of these devices on reduction in ventilator induced lung injury is not clearly demonstrated. This study aims to assess the reduction in ventilator induced lung injury with the use of ECCO2R device called Prismalung that is currently used in our intensive care unit. This assessment is done by measuring of pulmonary interleukins and blood interleukin levels as well as clinical assessment including the reduction of driving pressure.
