Blood flow change in rat hemorrhagic shock model. In order to simulate hemorrhagic shock in the rat, 5% of blood volume was withdrawn eight times with a 15-min interval in the first two hours and then resuscitation was performed for 15 min. OCTA imaging was performed right after every blood withdrawal and every 30 min for 1.5 h after resuscitation (a). (b) Shows time versus BFI values (mean ± SD, n = 5) of the retinal and the choroidal flows. Changes in BFI, MAP, and lactate are summarized in Table 2.
