TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)

The number of smokers within the home, the number of packs smoked in the home per day, and the amount of time that the dog spent within the home had no effect on the dog's risk for lung cancer. [5] In 1990, a tobacco-industry researcher in Germany proposed a study of the effects on animals of lifetime exposure to second-hand smoke.
This matching may be assessed in the lung as a whole, or in individual or in sub-groups of gas-exchanging units in the lung. On the other side Ventilation-perfusion mismatch is the term used when the ventilation and the perfusion of a gas exchanging unit are not matched. The actual values in the lung vary depending on the position within the lung.
A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs.A spirometer measures ventilation, the movement of air into and out of the lungs.
A respirometer is a device used to measure the rate of respiration [1] of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. [2] They allow investigation into how factors such as age, or chemicals affect the rate of respiration. [3]
Needle valves: Mass flow meters may be purchased with mass flow controllers which permit setting flow rates. These are expensive, however. These are expensive, however. Respirometry research often will attempt to measure more than one animal at a time, which would necessitate one chamber per animal and thus controlled flow through each chamber.
An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...
