Figure 3

Mean arterial blood pressure (MAP) and minute ventilation (VE) responses to hypercapnia (7% inspired carbon dioxide). Responses are presented as change from baseline levels (room air breathing) in protocol 1 (upper panels) and 2 (lower panels) before (Pre; closed symbols) and during (Post; open symbols) angiotensin II (left panels) or phenylephrine (right panels) infusion. Data are presented as 30 s mean values in response to the 3 min exposure. Both MAP and VE increased during hypercapnia. However, responses were not altered by infusion of low or high dose angiotensin II or phenylephrine. Values are mean±SE.
