●Class I hemorrhage involves a blood volume loss of up to 15 percent (< 750 ml). The heart rate is
minimally elevated or normal, and there is no change in blood pressure, pulse pressure, or respiratory
rate.
●Class II hemorrhage occurs when there is a 15 to 30 percent blood volume loss (750-1500) and is
manifested clinically as tachycardia (heart rate of 100 to 120), tachypnea (respiratory rate of 20 to
24), and a decreased pulse pressure, although systolic blood pressure changes minimally if at all.
The skin may be cool and clammy, and capillary refill may be delayed.
●Class III hemorrhage involves a 30 to 40 percent blood volume loss (1500-2000 ml), resulting in a
significant drop in blood pressure and changes in mental status. Any hypotension (systolic blood
pressure less than 90 mmHg) or drop in blood pressure greater than 20 to 30 percent of the
