Resting hemodynamic parameters prior to hemorrhage

	Treatment group
Parameter	Control	I-Saline	H-saline
HR, beats/min	332 ± 16	292 ± 17	306 ± 18
MAP, mmHg	123 ± 4	115 ± 4	116 ± 4
HQR, mmHg/kHz	59 ± 12	76 ± 15	72 ± 18
RR, mmHg/kHz	17 ± 2	16 ± 2	15 ± 3
MR, mmHg/kHz	18 ± 2	17 ± 2	15 ± 2

The data are presented as mean ± SEM. The group designated “Control” did not receive injections of either hypertonic or isotonic saline after hemorrhage. The group designated I-saline received injections of isotonic saline after hemorrhage. The group designated H-saline received injections of hypertonic saline after hemorrhage.

HR = heart rate. MAP = mean arterial blood pressure. HQR = hindquarter vascular resistance. RR = renal vascular resistance. MR = mesenteric vascular resistance.

Note that there were no between-group differences for any parameter (P > 0.05, for all comparisons).
