    A toxic condition that may occur during pregnancy, characterized by hypertension, edema, proteinuria, and seizures; also called toxemia of pregnancy.

  • ectopic

    Located away from normal position, as in ectopic pregnancy or ectopic focus.

  • ectopic focus

    A pacemaker site located in some part of the electric conduction system other than the sinoatrial node.

  • ectopic pregnancy

    A pregnancy in which the fetus is implanted elsewhere than in the uterus, e.g., in the fallopian tube or in the abdominal cavity.

  • edema

    The condition in which excess fluid accumulates in body tissue, manifested by swelling.

  • Eductor

    Proportioning device that injects foam concentrate into the water flowing through a hoseline or pipe.

  • Eductor

    Venturi device through which water flows under 200 psi pressure to create a partial vacuum in a tube attached at 90-degrees and open to the water stream passing overhead. The vacuum draws liquid foam concentrate from a reservoir, which mixes Read on! →
