what the risks are blood test, lactate, a test to measure the amount, lactic acid, in the blood, blood is drawn, a vein, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to apply pressure, restrict blood flow, the vein, veins below the band to fill, blood, a needle is inserted, vein, blood is collected in an air-tight vial, a syringe, band is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, an infant, young child, area is cleansed, antiseptic, punctured, a sharp needle, a lancet, blood collected, pipette, small glass tube, on a slide, onto a test strip, into a small container, cotton, a bandage applied, puncture site, any continued bleeding, , not exercise, several hours, infants, children, test depends on child's age, previous experience, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, the needle is inserted to draw blood, feel moderate pain, others feel only a prick, stinging sensation, some throbbing, this test, used, lactic acid accumulation is causing acidosis, acidotic body state, lactic acid, intermediate product of carbohydrate metabolism, derived mainly from muscle cells, red blood cells, exercise, lactate levels, increase, liver, metabolize more lactate than is produced, return lactate levels to normal, a few hours, 4.5 to 19.8 mg/dl, 0.5-2.2 mmol/l, mg/dl = milligrams per deciliter, mmol/l = millimoles per liter, severe oxygen deprivation of tissues results, switch from aerobic to anaerobic metabolism, lactate, main product of anaerobic metabolism, accumulates, is oxygen deprivation, hypoxia seen in shock, congestive heart failure, condition that would cause problems in oxygen picked up, transported, in the blood, hepatic, liver, dysfunction, ischemia, not enough oxygenated blood getting to a certain area, pulmonary, lung, insufficiency, all associated, increased serum lactate, excessive bleeding, fainting, feeling light-headed, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, clenching the fist, having the elastic band in place, long time having blood drawn, artificially increase lactic acid level, veins, arteries vary in size, obtaining a blood sample.
