Document Summary
Anemia is the reduction in rbc mass &/or hemoglobin concentration. Most common hematologic disorders of infancy & childhood. Can be caused by: inadequate production of rbc or rbc components, increased destruction of rbc, excessive loss of rbc through hemorrhage. Can be classified based on etiology or morphology. Rbc size (mcv: normocytic, microcytic, macrocytic. Rbc color (mch: normochromic, hypochromic, hyperchromic. Decreased rbc production: tachycardia, fatigue, weakness, headache, pallor, murmur. Heart is working harder to pump more blood out: frontal bossing. As body is trying to make more rbcs. Increased rbc destruction: tachycardia, fatigue, headache, jaundice, dark urine, hepatomegaly/splenomegaly. Rbcs go to liver & spleen to get recycled. Not able to meet demands of body: low bp. Monday, april 6, 2020: tachycardia, fatigue, weakness, headache, pallor, decreased pulses, cool skin, low bp. Etiology: inadequate iron supply, impaired iron absorption. Things that affect iron absorption: acid reducing meds for gerd, iron needs acid environment to be fully absorbed, increase need for iron.
