| blood volume nomogram | A nomogram used to predict blood volume on the basis of the individual's weight and height. (05 Mar 2000) |
| Radford nomogram | A nomogram used to predict necessary tidal volume for artificial respiration on the basis of respiratory rate, body weight, and sex; correction factors are supplied for activity, fever, altitude, metabolic acidosis, and alterations in dead space. (05 Mar 2000) |
| cartesian nomogram | A nomogram based on rectangular coordinates, representing two variables, on which a family of isopleths is superimposed for each of the additional variables involved. Origin: from R. Descartes, French philosopher and mathematician, 1596-1650 (05 Mar 2000) |
| Siggaard-Andersen nomogram | A nomogram used to predict acid-base composition of blood by the slope and position of a buffer line constructed when PCO2 on a logarithmic scale is plotted against pH. (05 Mar 2000) |
| nomogram | A form of line chart showing scales for the variables involved in a particular formula in such a way that corresponding values for each variable lie in a straight line intersecting all the scales. Synonym: nomograph. Origin: G. Nomos, law, + gramma, something written (05 Mar 2000) |
| d'Ocagne nomogram | An alignment chart consisting of an arrangement of three or more graduated lines (straight or curved), each constituting a scale of values of a variable, constructed so that any straight line crossing these scales connects the simultaneously compatible values; from values for any two variables, the values of all other variables can be determined.

| absorbancy index | Absorbance (of light) per unit path length (usually the centimeter) and per unit of mass concentration. Compare: molar absorption coefficient. Synonym: absorbancy index, absorptivity, extinction coefficient, specific extinction. (05 Mar 2000) |
| alveolar index | Relation between the basialveolar (basion to alveolar point) and basinasal (basion to nasion) lengths: (basialveolar length × 100)/basinasal length; the result indicates the degree of projection of the maxilla or upper jaw. Synonym: alveolar index. (05 Mar 2000) |
| anaesthetic index | Ratio of the number of units of anaesthetic required for anaesthesia to the number of units of anaesthetic required to produce respiratory or cardiovascular failure. (05 Mar 2000) |
| antitryptic index | An obsolete term for the relative retardation in loss of viscosity of a solution of casein incubated with trypsin, to which a drop of abnormal blood serum (as from a cancerous patient) has been added, compared with that in a similar solution to which normal serum has been added; if the former drips through the tube of the viscosimeter in 100 seconds, and the latter in 104 seconds, the antitryptic index is 4. (05 Mar 2000) |
| Arneth index | An expression based on adding the percentages of polymorphonuclear neutrophils with 1 or 2 lobes in their nuclei, plus one-half the percentage with 3 lobes; the normal value is 60%. See: Arneth formula, Arneth count. (05 Mar 2000) |
| auricular index | Relation of the width to the height of the auricle or pinna: (width of pinna × 100)/length of pinna. (05 Mar 2000) |
| Ayala's index | The cerebrospinal index when 10 ml of cerebrospinal fluid have been removed. Synonym: Ayala's quotient, spinal quotient. (05 Mar 2000) |
| basilar index | Ratio between the basialveolar line and the maximum length of the cranium, according to the formula: (basialveolar line × 100)/length of cranium. Synonym: alveolar index. (05 Mar 2000) |
