What happens to heart rate during hemorrhage?
Generally, a blood loss of <15% of total blood volume leads to only a small increase in heart rate and no significant change in arterial pressure.
When blood loss is 15 to 40%, mean arterial and pulse pressures fall, and heart rate increases, with the magnitude of these changes being related to how much blood is lost..
What happens to blood pressure during blood loss?
Decreases in blood volume: A decrease in blood volume can also cause blood pressure to drop. A significant loss of blood from major trauma, dehydration or severe internal bleeding reduces blood volume, leading to a severe drop in blood pressure.

Other symptoms This is especially true if internal bleeding occurs in locations where a substantial amount of blood can be lost, such as your chest, abdomen, or thigh. Shock occurs when there’s not enough blood to supply your whole body. Symptoms of shock include: rapid heart rate.
How does the body compensate for hemorrhage?
The body compensates for volume loss by increasing heart rate and contractility, followed by baroreceptor activation resulting in sympathetic nervous system activation and peripheral vasoconstriction. Typically, there is a slight increase in the diastolic blood pressure with narrowing of the pulse pressure.
What is the first sign of internal bleeding?
