In a prospective study, heart rate and mean arterial pressure were related to estimated blood loss in 34 consecutive patients aged 23-92 years during resuscitation from haemorrhagicshock. Eighteen patients with a blood loss of less than 3 1 (1-9[0-93-01 1) (median and range), corresponding to 34 (16-46) YO of estimated blood volume, had a heart rate of 83 (60-160) beats min-' and a mean arterial pressure of 62 (35-73) mmHg. In 16 patients with a blood loss of more than 3 1 (4.0 [3-3-5-0] 1) corresponding to 89 (35-100) YO of the estimated blood volume, heart rate was 120 (110-160) beats min-' (P
