End-tidal carbon dioxide (ETCO) monitoring is useful in many situations. However, ETCO monitoring is unreliable in patients with acute respiratory distress syndrome (ARDS) due to widespread lung inflammation. In our study, we attempt to establish the gradient between the arterial pressure of carbon dioxide (PaCO) and ETCO in patients with ARDS, which we defined as the PaETCO gradient.
