Physiologic cost index
The metabolic expenditure per unit of distance traveled. It is expressed as the number of heartbeats per meter traveled and is calculated by subtracting the resting heart rate from the exercise heart rate divided by the distance traversed.
-
Periodontal index
An extensive consideration of the periodontal status of six teeth by evaluating gingival condition, depth of gingival sulcus or pocket, plaque or calculus, attrition, tooth motility, and extent of tooth contact.
-
Pelvic index
The ratio of pelvic conjugate and transverse diameters. The comparison of the pelvic measurements from front to back with the width across; used to assess if the pelvis is spacious enough for a baby to pass through.

Oral hygiene index
A popular indicator developed in 1960 to determine oral hygiene status in epidemiological studies. The index consists of an oral debris score and a calculus score. Six indicator teeth are examined for soft deposits and calculus. Numerical values are assigned to the six indicator teeth according to the extraneous deposits present. The scores are added…

Gnathic index
A measure of the degree of projection of the upper jaw by finding the ratio of the distance from the nasion to the basion to that of the basion to the alveolar point multiplying by 100.
-
Gas exchange index
One of several measurements of the efficiency of respiration, especially of the extent of intrapulmonary shunting in respiratory failure. Among the commonly used gas exchange indices is the alveolar-arterial oxygen tension difference (a measurement derived from an analysis of the oxygen tension of an arterial blood gas, compared with the atmospheric oxygen content). The process…

Exposure index
A relative value indicating the quantity of ionizing radiation received by a digital radiographic image receptor. Although vendors currently use many kinds of exposure indices (i.e., Sensitivity Numbers), standardization is being developed by physicists’ organizations.
-
Dynamic gait index
A semiquantitative tool used to evaluate a patient’s ability to modify gait by changing task demands, especially in patients with dizziness and balance deficits. This test is used to identify patients, especially seniors, who are predisposed to falling. Patients are graded on their ability to vary speed, turn the head, turn the body, step over…

Chemotherapeutic index
The ratio of the toxicity of a drug, expressed as maximum tolerated dose per kilogram of body weight to the minimal curative dose per kilogram of body weight. This index is used in judging the safety and effectiveness of drugs.
-
Cerebral index
The ratio of greatest transverse to the greatest anteroposterior diameter of the cranium.
