Figure 2From: Non-invasive monitoring of tissue oxygenation during laparoscopic donor nephrectomy Renal parenchymal oxygen tension (pO 2 ) measured via a fluorescence probe, as the fraction of O 2 (FiO 2 ) is reduced over 65 minutes. The FiO2 is indicated with dashed arrows. The times of blood draws, where blood gas measurements were made (sO2), are indicated by BD.Back to article page
