Figure 1

Examples of recordings in two rats during and following acute hemorrhage. The breath-by-breath inspiratory flow ( V ˙ ), arterial blood pressure (ABP), minute ventilation ( V ˙ I ), body temperature (θ), carbon dioxide production ( V ˙ C O 2 ) and oxygen uptake ( V ˙ O 2 ) are displayed. Interruptions in ABP recording are due to blood withdrawal during each of the bleeding periods. Note the drop in arterial pressure, minute ventilation, V ˙ O 2 and V ˙ C O 2 , during each bleeding period (see text for more details). At the end of the five bleeding periods, all variables continued to either decrease slowly until death occurred (panel A, this response was observed in three out of eight control rats), or ABP, V ˙ I , V ˙ C O 2 and V ˙ O 2 rose transiently before subsiding again, leading to a fatal outcome (panel B, this response was observed in five out of eight control rats). The vertical arrow corresponds to the final cardio-respiratory arrest.
