Mean transit time is the area under the flow-volume curve divided by the forced vital capacity.
In order to even consider getting off the artificial respirator, a patient needs a vital capacity of 750 ccs.
Pulmonary function test demonstrates a decrease in the forced vital capacity.
A person's vital capacity can be measured by a wet or regular spirometer.
In combination with other physiological measurements, the vital capacity can help make a diagnosis of underlying lung disease.
A normal adult has a vital capacity between 3 and 5 litres.
Some of the parameters described by him are used today which included residual volume and vital capacity.
He also showed that vital capacity does not relate to weight at any given height.
I saw the smallness of the clouds as a diminished pulmonary vital capacity, from his cancer.
