Practical Implications
The maximum diving depth of the free diver is mainly determined by the ratio of the total lung capacity (TLC) of the lung to the residual volume (RV). Since free-diving depth is dependent on the tolerable compression of the lungs, until the middle of the 1950s diving doctors believed that free diving to beyond 40 meters depth led to lung trauma. The blood shift causes expansion of the lungs capillary volume resulting in a reduction of the residual volume and thus to an increase of the maximum possible depth. A redistribution of about 1.53 liters of blood to the pulmonary blood vessels has been shown.

Famous quotes containing the words practical and/or implications:
“Philosophy, certainly, is some account of truths the fragments and very insignificant parts of which man will practice in this workshop; truths infinite and in harmony with infinity, in respect to which the very objects and ends of the so-called practical philosopher will be mere propositions, like the rest.”
—Henry David Thoreau (1817–1862)
“The power to guess the unseen from the seen, to trace the implications of things, to judge the whole piece by the pattern, the condition of feeling life in general so completely that you are well on your way to knowing any particular corner of it—this cluster of gifts may almost be said to constitute experience.”
—Henry James (1843–1916)
