I can't imagine any good way for a wristwatch to measure core temperature (as compared to peripheral temperature), or blood pressure (without an obtrusive and annoying sphygmomanometer), or respiratory rate. Heart rate and O2 are cake by comparison.
The term âleft shiftâ means that a particular population of cells is âshiftedâ towards more immature precursors (meaning that there are more immature precursors present than you would normally see). Take the neutrophil series, for example. In normal blood, the neutrophils are virtually all mature (segmented).
The term shift work includes both long-term night shifts and work schedules in which employees change or rotate shifts.
