Residual volume: the volume of air remaining in the lungs after a maximal exhalation: ERV: Expiratory reserve volume: the maximal volume of air that can be exhaled from the end-expiratory position: IRV: Inspiratory reserve volume: the maximal volume that can be inhaled from the end-inspiratory level: IC: Inspiratory capacity: the sum of IRV and ...
Output of a spirometer. Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation.It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume.
FRC is the sum of expiratory reserve volume (ERV) and residual volume (RV) [2] and measures approximately 3000 mL in a 70 kg, average-sized male. [1] [2] It cannot be estimated through spirometry, since it includes the residual volume.

Minute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels .
Tidal volume (symbol V T or TV) is the volume of air inspired and expired with each passive breath. [1] It is typically assumed that the volume of air inhaled is equal to the volume of air exhaled such as in the figure on the right. In a healthy, young human adult, tidal volume is approximately 500 ml per inspiration at rest or 7 ml/kg of body ...
Rolling chip drop or volume is the amount of rolling chips wagered and dropped at the table (like cash is dropped). Winnings are paid out in cash-equivalent chips. A casino records revenue based ...
In obstructive lung disease, the FEV1 is reduced due to an obstruction of air escaping from the lungs. Thus, the FEV1/FVC ratio will be reduced. [4] More specifically, according to the National Institute for Clinical Excellence, the diagnosis of COPD is made when the FEV 1 /FVC ratio is less than 0.7 or [8] the FEV 1 is less than 75% of predicted; [9] however, other authoritative bodies have ...
