vent-

A rapid ventricular rhythm, approximately 60 to 110 beats per minute: "Accelerated idioventricular rhythm usually results from premature beats or an escape rhythm generated by the slowing of the sinus pacemaker or acceleration of a ventricular pacemaker."

Mechanical ventilation used in assisting breathing when deficient, or completely assuming control of breathing in the presence of apnea (non breathing).

Mechanical ventilation that takes the place of natural inspiration and expiration in th management of pulmonary insufficiency.

A geyser on the sea bottom through which super-hot aqueous solutions rise from the magma beneath the crust.

This creates a surrounding system of mineral-rich water that helps to support a distinctive type of ecosystem not found in typical cold-water environments at the same ocean depth.

The removal of used or foul air from a room, or building, by means of a fan or other mechanical process, as seen in certain dangerous or noxious trade processes.

1. A fissure in the sea bottom through which hot aqueous solutions rise from the magma beneath the crust.
2. A geyser on the sea bottom through which super-hot aqueous solutions rise from the magma beneath the earth's crust.

This creates a surrounding system of mineral-rich water which helps to support a distinctive type of ecosystem not found in typical cold-water environments at the same ocean depth.

1. To breathe unusually deeply or rapidly because of anxiety or organic disease and in excess of the body's requirements, causing too much loss of carbon dioxide.
2. Abnormally increased pulmonary ventilation, resulting in reduction of carbon dioxide tension, which, if prolonged, may lead to alkalosis (a dangerous decrease in the normal acidity of the blood which can be caused by high altitudes, hyperventilation, and/or excessive vomiting).

A condition of breathing faster and/or deeper than necessary, bringing about light headedness and other undesirable symptoms often associated with panic attacks.

1. Extremely rapid or deep breathing that over oxygenates the blood, causing dizziness, fainting, etc.
2. An excessive rate and depth of respiration leading to an abnormal loss of carbon dioxide from the blood.

1. Abnormally slow and shallow respiration, resulting in an increased level of carbon dioxide in the blood.
2. A condition in which there is a reduced amount of air entering the pulmonary (lung) alveoli (small cell containing air in the lungs), resulting in decreased levels of oxygen and increased levels of carbon dioxide in the blood.

Hypoventilation can be a result of breathing that is too shallow (hypopnea) or too slow (bradypnea) or to diminished lung function.

An apparatus for artificial ventilation of a patient who has weak or paralyzed respiratory muscles, consisting of a rigid tank which encloses the body from the neck down.

Changes of pressure of air within the tank bring about inspiration and expiration.

1. Any opening designed to allow air, water, or pressure to enter or to escape from a confined space; such as in a building or in a mechanical system.
2. An opening, commonly small, for the passage of liquids, gases, etc.
3. An opening at the surface of the earth through which volcanic material is ejected, or the conduit through which such material passes.
4. Utterance, expression; primarily used in the phrase to give vent to.
5. In zoology, the external opening of the alimentary canal; especially of animals below mammals.
6. To relieve, as by giving vent to emotion.
7. To permit to escape from an opening.
8. Etymology: the verb "provide with an outlet", came from Old French esventer from Vulgar Latin exventare, "to let air out"; which was formed from the Latin prefix ex-, "out" and ventum, "wind".

1. A passage for wind or air.
2. A passage, or pipe, for ventilating apartments or rooms.
3. In a building, a passage for wind or air; a subterraneous passage or spiracle for ventilating apartments.
