Experimental protocol. BL: baseline, W1-W7: blood withdrawal (5% of total blood volume), CR1-CR6: fluid replacement maneuvers, Zrs: a set of respiratory impedance measurements, BG: arterial blood gas measurements. Each withdrawal-replacement step lasted about 12–15 min, resulting in a total duration of the fluid resuscitation period of around 90 min
