vent- +

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.

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. 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. 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.

A rock, stone, or pebble that has been shaped, cut, or polished by wind-blown, or wind-driven, sand.

1. A device that controls the flow of a gas or fluid through a pipe.
2. An apparatus that allows fuel and air into the cylinder of an internal combustion engine, or one that makes it possible for combustion gases to exit.
3. In anatomy, one or more membranous partitions, flaps, or folds, which permit the passage of the contents of a vessel or cavity in one direction, but stop or retard the flow in the opposite direction; such as, the ileocolic (small intestine and large intestine valve), mitral (heart valve), and semilunar (valves at the beginning of the artery of the heart).

That which can be ventilated.

1. To provide a room, or other enclosed space, with fresh air or a current of air.
2. To provide an enclosed space with a vent or other means of letting fresh air in and stale air out.
3. To expose something to moving fresh air in order to dry, cool, or preserve it.
4. To oxygenate, or to aerate, the blood through the blood vessels of the lungs.
Etymology: "to blow away something" (as in the wind); from Latin ventilatus, past participle of ventilare, "to brandish, to toss in the air, to winnow, to fan, to agitate, to set in motion"; from ventulus, "a breeze" a diminutive of ventus, "wind".

1. The act of supplying fresh air and getting rid of foul air.
2. A mechanical system in a building that provides fresh air.
3. The bodily process of inhalation and exhalation which includes the process of taking in oxygen from inhaled air and releasing carbon dioxide by exhalation.
4. The replacement of stale or noxious air with fresh air.

Ventilation is a process of moving or circulating air, so as to supply outside air to an enclosed space and/or to remove stale air from the area, with the purpose of cooling, purification, moisture reduction, etc.; which may or may not involve mechanical conditioning.
