| Fick method | In 1870 A. Fisk proposed that cardiac output can be calculated as the quotient of total body oxygen consumption divided by the difference in oxygen content of arterial blood and mixed venous blood. In the direct Fick method all variables are measured. The indirect Fick method employs a variety of means to avoid measuring mixed venous oxygen content. By extension, the Fick method may be used to measure cardiac output or organ blood flow with any indicator substance for which the rate of uptake or consumption, and the arterial and mixed venous concentrations, can be measured, provided the indicator does not enter or leave the system by any route not being measured. Synonym: Fick principle. (05 Mar 2000) |

| fick's law of diffusion | The principle that a substance put into solution will tend to diffuse towards constant concentration throughout the solution. (09 Oct 1997) |
| Fick's laws of diffusion | The direction of movement of solutes by diffusion is always from a higher to a lower concentration and the diffusive flux JA of solute A across a plane at x is proportional to the concentration gradient of A at x; i.e., JA = -D(CA/x), the increase of concentration of solute A with time, CA/t, is directly proportional to the change in the concentration gradient, i.e., CA/t = D(fl2/x2).

| anaemic halo | Pale, relatively avascular areas in the skin seen around vascular spiders, cherry angiomas, and sometimes in acute macular eruptions. (05 Mar 2000) |
| glaucomatous halo | A yellowish white ring surrounding the optic disk, indicating atrophy of the choroid in glaucoma. Synonym: glaucomatous ring. A halo surrounding lights, caused by corneal oedema in glaucoma. Synonym: rainbow symptom. (05 Mar 2000) |
| halo | <radiobiology> The cold, dense plasma formed outside the last closed flux surface during a vertical displacement event. The large currents which flow through this plasma stop the displacement and transfer the force to the vacuum vessel. If care is not taken in design, the halo currents can be large enough to threaten the structural integrity of the vacuum vessel or in-vessel components. Whereas the centre of a tokamak plasma is too hot for material probes to survive, probes (such as magnetic-field coils) can sometimes be placed in the halo, and can measure things such as the halo current. See: vertical instability. (09 Oct 1997) |
| halo blight | Halo blight is a fatal plant disease which attacks legumes and is caused by the bacteria Pseumonas phaseolicola. The plant develops yellow-ringed, water-soaked spots, then withers and dies without rotting. (09 Oct 1997) |
| halo cast | A cast applied to the shoulders in which metal bars are set that extend over the head to a halo, from which traction may be applied to the head by means of tongs or a halter. (05 Mar 2000) |
| halo current | <radiobiology> Currents in the halo region of a plasma discharge. See: halo. (09 Oct 1997) |
| halo effect | The effect (usually beneficial) that the manner, attention, and caring of a provider have on a patient during a medical encounter, regardless of what medical procedure or services the encounter involves, the influence upon an observation of the observer's perception of the characteristics of the individual observed (other than the characteristics under study) or the influence of the observer's recollection or knowledge of findings on a previous occasion. (05 Mar 2000) |
| halo melanoma | <tumour> A rare condition in which a melanoma is surrounded by an irregular area of depigmentation. (05 Mar 2000) |
| halo nevus | A benign, sometimes multiple, melanocytic nevus in which involution occurs with a central brown mole surrounded by a uniformly depigmented zone or halo. Synonym: leukoderma acquisitum centrifugum, Sutton's disease, Sutton's nevus. (05 Mar 2000) |
| halo sign | <radiology> Narrow, radiolucent ring surrounding breast lesion, indicates benign tumour, rare exceptions: intracystic carcinoma, papillary carcinoma, carcinoma arising in fibroadenoma (12 Dec 1998) |
| Fick's halo |
A colored halo around light observed by some persons as a result of wearing contact lenses.
