Blood shift

Blood shift has at least two separate meanings:

  • In medicine, it is synonymous with left shift.
  • In biology, it may refer to a phenomenon that is seen when mammals submerge in water. It is part of the mammalian diving reflex. Blood vessels in the extremities contract, leaving a higher percentage of the entire blood volume in the torso. An effect that is important for freedivers is the resulting widening of the lung's capillaries. It reduces the lung's residual volume, thus increasing the depth at which the residual volume is reached (the average for untrained persons is about 30 meters, or 98.4 feet). According to Yasemin Dalkılıç, she can feel plasma enter her sinuses when diving to extreme depths while participating in free diving competitions. See also: immersion diuresis

    • Free diving

    Mechanism

    When the body is immersed, the diving reflex will contract the circular muscle in blood vessels of the arms and legs, reducing the total volume of blood vessels in the body. Therefore, a greater proportion of blood volume will remain in the torso, moved mainly in the pulmonary artery. This results in an increase in blood pressure, and shrinkage of the alveoli. The increased external pressure creates a pressure differential with the lungs, leading to a further influx of venous blood into the lung cavity. The blood vessels in the lungs expand and fill, and the alveoli contract still further.
