Air introduced into a spinning propeller from the water's surface.
To provide a patient with oxygen.
movement of air (gases) in and out of the lungs.
Mechanical support with breathing, so that the baby will be able to have normal levels of oxygen and carbon dioxide in their blood.
Ventilation is the systematic removal of smoke from a building. Ventilation is usually accomplished with one of two methods: positive and negative pressure ventilation. ...
Creates a positive flow of air that allows the house to "breathe" and helps prevent moisture build-up year-round.
the process through which oxygen and carbon dioxide are exchanged between the lungs and the air; also refers to the use of a machine to carry out this process in someone who cannot breathe on his or her own
Necessary in all buildings to disperse moisture resulting from bathing, cooking, breathing, etc, and to assist in prevention of condensation. Floors: necessary to avoid rot, especially dry rot, achieved by airbricks near to the ground level. ...
Process by which outside air is conveyed to an indoor space. Volatile Organic Compound (VOC): Organic substances capable of entering the gas phase from either a liquid or solid form.
The circulation of air through a building to provide fresh air to the occupants and to deliver heating and cooling to the occupied spaces. End-use estimates are estimated for ventilation and eight other end uses. (See Energy End Use.)
Circulation of fresh area and exhaust gases.
is the process of circulating stale indoor air to the outside and bringing fresh outdoor air into a building.
General term for the heating, ventilation and air conditioning system in a building. System efficiency and design impact the overall energy performance of a home and its indoor environmental quality. ...
This is the process for mechanically circulating the air in a confined space to create or maintain a safe atmosphere.
Airflow through a projector's internals for the purpose of cooling the lamp, or light source.
All the components of the appliance used to condition interior air of a building.
In biology this term is often applied to the mechanics of moving air in and out of the gas-exchange surfaces of the lungs.
The exchange of air between the lungs and the atmosphere so that oxygen can be exchanged for carbon dioxide in the alveoli (the tiny air sacs in the lungs). See the entire definition of Ventilation
is the effect of air sucked down by the propeller from the water's surface. Ventilation will lead to vibration and loss of thrust. Ventilation can be corrected by just simply putting the propeller deeper under the surface of water.
Adequate air movement, needed particularly when using solvent-based products and aerosols in confined areas. As well as having suitable ventilation you should take regular breaks to avoid over-exposure to solvent fumes.
the act of supplying fresh air and getting rid of foul air a mechanical system in a building that provides fresh air; 'she was continually adjusting the ventilation' public discussion: free and open discussion of (or debate on) some question of public interest; 'such a proposal deserves thorough public discussion' breathing: the bodily process of inhalation and exhalation; the process of taking in oxygen from inhaled air and releasing carbon dioxide by exhalation
In respiratory physiology, ventilation (or ventilation rate) is the rate at which gas enters or leaves the lung. It is categorised under the following definitions: *Gas exchange
Ventilation is the intentional movement of air from outside a building to the inside. It is the V in HVAC. ...
In firefighting, ventilation refers to the tactic of creating a draft with an opening above or opposite the entry point so that heat and smoke will be released, permitting the firefighters to find and attack the fire. ...
The replacement of stale or noxious air with fresh; The mechanical system used to circulate and replace air; An exchange of views during a discussion; The bodily process of breathing; the inhalation of air to provide oxygen, and the exhalation of spent air to remove carbon dioxide
