(redirected from deviation to the left)

shift

 [shift]
a change or deviation.
antigenic shift a sudden, major change in the antigenicity of a virus, seen especially in influenza viruses, resulting from the recombination of the genomes of two different strains; it is associated with pandemics because hosts do not have immunity to the new strain. See also antigenic drift.
chloride shift the exchange of chloride and carbonate between the plasma and the erythrocytes that takes place when the blood gives up oxygen and receives carbon dioxide. It serves to maintain ionic equilibrium between the cell and surrounding fluid.
mediastinal shift a shifting to one side of the tissues and organs of the mediastinum; see also mediastinal shift.
shift to the left
1. a change in the blood picture, with a preponderance of young neutrophils.
2. an increased oxygen affinity of hemoglobin.
shift to the right
1. a preponderance of older neutrophils in the blood picture.
2. a decreased oxygen affinity of hemoglobin.
weight shift
1. the frequent movement of a paralyzed or partially paralyzed patient to redistribute the patient's weight and prevent impairment of circulation, which leads to pressure sores. One variation is the wheelchair pressure release.
2. relocation of a patient's center of mass in order to allow movement; see also gait.

shift to the left

1. a marked increase in the percentage of immature cells in the circulating blood, based on the premise in hematology that the bone marrow with its immature myeloid cells is on the left, whereas the circulating blood with its mature neutrophils is on the right; Synonym(s): deviation to the left
2.

shift to the left

in hematology, a predominance of immature leukocytes noted in a differential white blood cell count. It is usually indicative of an infection or inflammation. The term derives from the Arneth classification, a graph of blood components in which immature cell frequencies appear on the left side of the graph.

shift to the left
an alteration in the distribution of leukocytes in the peripheral blood in which there is an increase in the numbers of immature neutrophils, primarily band forms but metamyelocytes or more immature cells may also be present; usually in response to an infection.
