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.

Doppler shift  the magnitude of frequency change due to the Doppler effect.
shift to the left  an increase in the percentage of neutrophils having only one or a few lobes.

Etymology: AS, sciftan, to divide
1 (in nursing) the particular hours of the day during which a nurse is scheduled to work. The day shift is usually 7:00 am to 3:00 pm or 8:00 am to 4:00 pm. The evening shift is usually 3:00 pm to 11:00 pm or 4:00 pm to 12:00 midnight, and the night shift the remaining hours. The evening shift is also called "relief," presumably because nurses originally worked 12-hour shifts and the evening and night shift was thought to be relief for the day nurse. Many innovations in staffing practice currently allow variations on the traditional 5-day, 40-hour week, such as nurses electing to work a shorter week, preferring longer hours for fewer days.
2 an abrupt change in an analytic system that continues at the new level.

Patient discussion about shift

Q. I started a new job a month ago – it’s night shifts as a security guard in a large office building I don’t know why, but I started feeling very down in the last week. Can it be that the change in waking hours is effecting me?

A. there are dozens of studies about night shift workers that try to connect them to all sort of things. and there is a good reason- our hormonal balance is maintained by our Hypothalamus (an area in the brain). being awake on night time changes it's function, it changes our hormonal system balance and other things around our brain. this can easily cause things like depression amongst some people.
