are considered ACUTE or CHRONIC blood loss anemia?
CHRONIC
Increased RBC destruction hemolytic anemias can be broken down into what TWO type of Hemolytic anemias?
INTRINSIC & EXTRINSIC (Aquired Hemolytic anemia)
- Abnormal hemoglobin (Hb S–sickle cell anemia)

this is INTRINSIC or EXTRINSIC (Acquired Hemolytic Anemia)
INTRINSIC
- Physical trauma (prosthetic heart valves, extracorporeal circulation)
