Anemia Flashcards
What causes anemia?
Increased RBC destruction, hemorrhage, decreased production
Signs of anemia?
Tachypnea, dyspnea, pale mm, tachycardia, lethargy, excessive intolerance, heart murmur
Three classifications of anemia.
Bone marrow, erythrocyte size and hemoglobin
Two types of anemia?
Regenerative vs non regenerative
Often caused by blood loss or hemorrhage.
Regenerative anemia
Caused by a lack of circulating immature RBCs
Non regenerative anemia
Bone marrow doesn’t produce new cells to replenish blood.
Aplastic anemia
Defective function of blood forming organs
Hypoplasia anemia
Affects the precursors to red blood cells but not white blood cells.
Aplasia anemia
IMHA
Immune mediated hemolytic anemia
Secondary causes to the idiopathic IMHA.
Vaccines, neoplasia, drugs
Signs of IMHA
WEAKNESS, tachpnea, lethargy, jaundice, dark urine, anorexic, vomiting, fever, tachypnea, heart murmur
What causes jaundice during IMHA?
Liver enzymes elevated
Antibodies causes the cells to become clumpy
Auto agglutination
Cells on a smear that suggests IMHA.
Spherocytes, agglutination, ghost cells
