In typical settings, oxygen and carbon dioxide concentrations are not measured directly, but their uptake and production fluxes, respectively, are measured through off-gas analysis on the bioreactor.
Changes in ECMO settings affect both oxygen and carbon dioxide.
Ventilator settings in PCV achieved a partial carbon dioxide tension of 35-45 torr and a partial oxygen tension greater than 60 torr on an FiO2 of 0.60 or less.
Carbonated drinks contain carbon dioxide gas.
Preliminary studies showed these respiratory settings resulted in normal partial pressure of arterial carbon dioxide (PaCO2) values after five hours of MV in the different mice strains.
Gas exchange in PT with the DLET remained stable without any variation in oxygenation and carbon dioxide levels, although the same settings of mechanical ventilation.
In brief, Zimmermann and colleagues were able to demonstrate efficient carbon dioxide removal at markedly reduced respiratory settings after 2 hours and even more so after 24 hours.
Ventilator settings were adjusted to maintain an arterial partial pressure of carbon dioxide (PaCO2) between 35 and 40 mmHg.
The end-tidal carbon dioxide (EtCO2) correlates with cardiac output in experimental settings [10].
In all conditions tested, carbon dioxide had a long time to equilibrium after changes in ECMO settings.
The trachea was again intubated; the lungs were ventilated with unchanged ventilator settings, except that the respiratory rate was increased in order to normalize end-tidal carbon dioxide.
