What Is Minimal Volume Lungs

Minimal volume (MV, gas plus tissue volume at zero transpulmonary pressure) was determined in excised dog lobes after inflation with air and with saline. MV was significantly greater in saline-filled lobes than air-filled lobes.

What is the minimal volume?

In mathematics, in particular in differential geometry, the minimal volume is a number that describes one aspect of a smooth manifold’s topology. This topological invariant was introduced by Mikhael Gromov. Any closed manifold can be given an arbitrarily small volume by scaling any choice of a Riemannian metric.

What are the 4 types of lung volume?

Four standard lung volumes, namely, tidal (TV), inspiratory reserve (IRV), expiratory reserve (ERV), and residual volumes (RV) are described in the literature. Alternatively, the standard lung capacities are inspiratory (IC), functional residual (FRC), vital (VC) and total lung capacities (TLC).
