<human>:  How much blood can a person loose before they die?
<bot>: Loss of significant amounts of blood, such as more than half of your total blood volume, can be life-threatening and can cause serious medical problems. You should seek immediate medical attention if you are bleeding heavily. Acute blood loss can lead to shock, which is a serious medical emergency requiring immediate medical treatment. Human blood loss is generally considered significant if more than 20% of your total blood volume is lost. For a typical adult male, this is around 500 milliliters of blood, or about 2 cups. Signs of shock include pale or bluish skin, rapid and weak pulse, restlessness or confusion, shortness of breath, dizziness or fainting, and weak or inhibited urination.
