Toward Respiratory Support of Critically Ill COVID-19 Patients Using Repurposed Kidney Hollow Fiber Membrane Dialysers to Oxygenate the Blood

Table 3

Blood gas measurements at the inlet and outlet of HFMD at 500 ml/min blood flow rates over three runs. A Leoceed-21N HFMD was used for the first two runs and a Leoceed-18N was used for the third run. Measurements are reported as averages over n samples ±1 standard deviation uncertainty.
