  • ventilation

    Breathing, moving air in and out of the lungs.

  • Ventilation

    Important procedure in firefighting in which the hot smoke and gases are removed from inside a structure, either by natural convection or forced, and either through existing openings or new ones provided by firefighters at appropriate locations (e.g., "vertical ventilation" Read on! →

  • Ventilation saw

    A high-powered saw with metal-cutting teeth or disc for quickly making large openings in roofing materials. Often, a chain saw with an attached guard to limit the depth of cut.

  • ventral

    Rapid, tremulous, and ineffectual contractions of the cardiac ventricles; cardiac arrest.

  • ventricular standstill

    Asystole with sinus p waves.

  • ventricular tachycardia

    Rapid, repetitive firing of a ventricular ectopic focus; a life-threatening dysrhythmia.

  • Venturi effect

    Creating a partial vacuum using a constricted fluid flow, used in fire equipment for mixing chemicals into water streams, or for measuring flow velocity.

  • Venturi Principle

    When a fluid is forced under pressure through a restricted orifice, there is a decrease in the pressure exerted against the side of the constriction and a corresponding increase in the velocity of the fluid. Because the surrounding air is Read on! →
