- Increasing patient arterial pCO2 on extracorporeal membrane oxygenation (ECMO).

CategoryCausesResponse
ECMO-relatedi. Gas flow rate is too lowi. ↑ Sweep gas flow
 ii. Oxygenator failureii. Check pre- and post-oxygenator blood gases
Patient-relatedi. Pneumothoraxi. CXR
 ii. Hemothoraxii. Pulmonary cultures
 iii. Ventilator-associated pneumoniaiv. PEiii. Bronchoscopyiv. CT PE
Ventilator-relatedInadequate ventilationAdjust ventilator parameters
pCO2: partial pressure of carbon dioxide, PE: pulmonary embolism, CXR: chest x-ray, CT: computed tomography
