Click the link for more information. .Volume one of the fundamental quantities associated with geometric solids. In the simplest cases volume is measured by the number of unit cubes that can fit in the solid, that is, the number of cubes with an edge of unit length. The problem of calculating the volumes of very simple solids stems from practical needs and was a stimulus to the development of geometry. The mathematics of the ancient East—Babylonia and Egypt—had a number of mostly empirical rules for calculating the volume of such frequently encountered solids as prismatic beams, whole and truncated pyramids, and cylinders. The volume formulas included inaccurate ones. The percentage error resulting from the use of inaccurate formulas was slight only within the limits of the linear dimensions commonly encountered in solids. The Greek mathematicians of the last centuries before the Common Era freed the theory of volume calculation from approximate empirical rules. Euclid’s Elements and the works of Archimedes contain only exact rules for calculating the volumes of polyhedrons and certain round solids, namely, the cylinder, cone, sphere, and parts thereof. In their theory of volumes of polyhedrons, Greek mathematicians had to overcome the considerable difficulties that make this branch of geometry substantially different from the related branch dealing with the areas of polygons. Not until the early 20th century was the reason for this difference found. Using rectilinear cuts it is possible to dissect a polygon into parts that can be rearranged into a square. Dehn showed in 1901 that the analogous transformation of an arbitrary polyhedron into a cube by means of plane cuts is in general impossible. That is why, in establishing the formula for the volume of a tetrahedron, the simplest of all polyhedrons, Euclid had to resort to an infinite process of successive approximations—the method of exhaustion. An infinite process also underlies the modern treatment of volume measurement. The modern approach considers all possible polyhedrons inscribed in the solid K and all possible polyhedrons circumscribed about K. The calculation of the volume of a polyhedron reduces to the calculation of the volume of the polyhedron’s constituent tetrahedrons. Let {Vi} be the set of volumes of the polyhedrons inscribed in K and {Vd} be the set of volumes of the polyhedrons circumscribed about K. The set {Vi} is bounded from above by the volume of any circumscribed polyhedron, and the set {Vd} is bounded from below by, for example, the number 0. The least upper bound of {Vi} is called the inner volume V̱ of K, and the greatest lower bound of {Vd} is called the outer volume V̱ of K. If $V coincides with V, then the number V = V = V is called the volume of K, and K is said to be Jordan measurable. A necessary and sufficient condition for a solid to be measurable is that for any positive number ∊ there exist a polyhedron circumscribed about the solid and a polyhedron inscribed in the solid such that the difference Vd – Vi of their volumes is less than ∊. Analytically, volume can be expressed by means of multiple integrals. Let the solid K (Figure 1) be bounded by a cylindrical surface with generators parallel to the z-axis, by the Jordan-measurable region M of the plane xOy, and by the surface Figure 1 z = f(x, y), which is intersected by any line parallel to a generator of the cylinder at exactly one point. The volume of such a solid can be calculated by means of the double integral V = ∫∫Mf (x, y) dxdy The volume of a solid bounded by a closed surface that meets a line parallel to the z-axis at no more than two points can be calculated as the difference of the volumes of two solids of the kind just described. The volume of a solid can also be expressed by the triple integral Figure 2 where the integration extends over the part of space occupied by the solid. Sometimes it is convenient to calculate the volume of a solid in terms of cross sections. Let a solid (Figure 2) lying between the planes z = a and z = b, b > a, be cut by planes perpendicular to the z-axis. If all cross sections of the solid are measurable and the cross-sectional area S is a continuous function of z, then the volume of the solid can be expressed by the simple integral Historically, the operation of integration was actually used (in various geometric forms) to calculate the volumes of simple solids—the pyramid, the sphere, and some solids of revolution—long before the development of the integral calculus. Thus the way was prepared for the development of the integral calculus in the 17th and 18th centuries. In particular, Cavalieri’s principle, which is still important as a teaching device, contained formula (1) in embryonic form. Simpson’s rule, which is appropriate when the function S(z) in (1) is a polynomial of at most third degree, is also useful in elementary instruction. REFERENCESKudriavtsev, L. D.

This refers to dehydration, water loss alone without change in sodium. See also volume" >fluid volume. Formerly called fluid volume deficit.
When a person engages in normal physical activity and the environmental temperature is 20°C (68°F), the body loses about 2400 ml of water in 24 hours. About 1400 ml are lost in urine, 200 ml in feces, and 100 ml in sweat. The remaining 700 ml are lost through what is called insensible water loss, which takes place by diffusion through the skin and by evaporation from the lungs. About 300 ml of water diffuse through the epithelial cells daily. The lungs excrete about 400 ml per day. A deficit of fluid volume occurs when there is either an excessive loss of body water or an inadequate compensatory intake. Etiologic factors include active loss through vomiting, diarrhea, gastric suctioning, drainage through operative wounds and tubes, burns, fistulas, hypermetabolic states, and drug-induced diuresis. Insufficient intake of water can be caused by nausea, immobility with inaccessibility of water, and lack of knowledge about the necessity of adequate fluid intake.Patient Care. Assessment of the patient's hydration status includes monitoring lab data for such signs as increased packed red blood cell volume, increased plasma protein level, elevated specific gravity of urine, and increased blood urea nitrogen (BUN) out of proportion to a change in serum creatinine. In the absence of other problems, the serum sodium should remain within normal limits.
Recording daily weight gives information about the amount of water gained or lost each day. If there is a fluid volume deficit, intake and output measurements can give evidence of fluid imbalance. The urine appears concentrated and is usually well below the criterion of 50 ml of output per hour. Other objective assessment data include hypotension and a decrease in venous filling and in pulse volume and pressure. The mucous membranes are dry, as is the skin, which loses its turgor. The patient may complain of thirst and the body temperature may be elevated. Patients at risk for profound and potentially fatal fluid volume deficit, as in severe burns, should be assessed frequently for mental acuity status and orientation to person, place, and time. Measures to improve hydration status should take into account the patient's ability to drink and retain fluids by mouth, preferences for certain fluids, and whether hot or cold drinks are preferred. The goal of oral fluid intake should be about 2000 ml per day. Explanations about the importance of an adequate fluid intake and assuring the availability of fresh water and fluids attractive to the patient can help reach the desired goal. Intravenous administration of fluids, especially isotonic saline, may be necessary if oral replacement is not possible. In severe and intractable fluid volume deficit a central venous catheter may be used to evaluate the extent of fluid loss and to guide replacement therapy.excess fluid volume a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as increased isotonic fluid retention; see also volume" >fluid volume. Factors contributing to this include (1) arterial dilatation, as occurs in the inflammatory process; (2) reduced oncotic pressure, as in hypoproteinuria (particularly a deficit of albumin, which is responsible for 80 per cent of oncotic pressure), lymphatic obstruction, and increased capillary permeability, which allows water to escape into the tissues and produce swelling; (3) renal retention of sodium and consequently of water, as seen in renal failure; (4) inadequate circulation of blood through the general circulation, as in heart failure" >congestive heart failure, or through the portal circulation, as in liver failure; and (5) overproduction or administration of adrenocortical hormones.
Hypervolemia can occur when a patient receives excessive fluid replacement or repeated tap water enemas or, much less frequently, drinks more fluids than are eliminated. Characteristics of fluid volume excess include obvious swelling, localized or generalized; weight gain; pulmonary congestion with accompanying shortness of breath, orthopnea, and abnormal breath sounds; a fluid intake greater than output; distended neck veins; and changes in central venous and pulmonary artery pressures.expiratory reserve volume the maximal amount of gas that can be exhaled from the resting end-expiratory level.fluid volume the volume of the body fluids, including both intracellular fluid and extracellular fluid.forced expiratory volume (FEV) the volume that can be exhaled from a full inhalation by exhaling as forcefully and rapidly as possible for a timed period.
