General guidelines include:
- Too much blood collected at any one time may cause hypovolemic shock, physiologic stress and even death. If smaller volumes are collected too frequently, anemia may result.
- As a general rule, 10% of the total blood volume can be collected at any one time every 2-4 weeks, or 1% at more frequent intervals of 24 hours or more. The total blood volume can be calculated as approximately 7.5% of body weight.
- The estimated volume at exsanguination is approximately one half of the total volume.
