Official Title: Clinical Study to Determine the Optimal Operation Parameters During CO2 Removal With the Abylcap® System.
Brief Summary:
This prospective study includes 5 patients with ARDS (Acute Respiratory Distress Syndrome) treated by mechanical ventilation. In case of respiratory acidosis, extracorporeal CO2 (carbon dioxide)removal might be necessary. We hereby work with the Abylcap system with the oxygenator Lilliput2 as CO2 remover (Bellco, Italy).
The patients (M/V) are older than 18, not pregnant, have a BMI<30, and no contraindication for anticoagulation therapy.
Under standard conditions patients are treated with a blood flow of QB=300mL/min and a gas flow (100% 02) of QG=7L/min. Blood sampling is performed from the arterial bloodline in the patients at 0, 1h, 3h, 24h, 48h, 72h, 96h, and 120h.
A parameter study is also performed to optimise CO2 removal. Herewith, blood samples (1mL) are taken from the inlet and outlet line of the Lilliput2 at the previously mentioned time points and for different flow setting: Blood flow (QB) 200-300-400mL/min and gas flow (QG) 1.5, 3, 6, 7, 8L/min
Blood samples are analysed for the different blood gases from which the extraction in the CO2 remover can be calculated for each setting of QB (blood flow) and QG (gas flow).
Detailed Summary:
Sponsor: University Hospital, Ghent
Current Primary Outcome: calculation of CO2 extraction in blood samples during mechanical ventilation [ Time Frame: during mechanical ventilation with CO2 removal (max up to 120h) ]
Original Primary Outcome: Same as current
Current Secondary Outcome: Based on the extraction rates, the optimum parameter settings are derived [ Time Frame: During mechanical ventilation with CO2 removal (max up to 120h) ]
Original Secondary Outcome: Same as current
