| pursed lips breathing | A technique in which air is inhaled slowly through the nose and mouth and exhaled slowly through pursed lips; used by patients with chronic obstructive pulmonary disease to improve their breathing by increasing resistance to air flow, forcibly dilating small bronchi.

|---|---|
| stertorous breathing | Harsh, noisy breathing usually heard in an comatous patient. Synonym: stertorous breathing. (05 Mar 2000) |
| intermittent positive-pressure breathing | Application of positive pressure to the inspiratory phase of spontaneous respiration. See: controlled mechanical ventilation (12 Dec 1998) |
| kussmaul breathing | Air hunger. (12 Dec 1998) |
| 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) |
| Bodecker index | A modification of the DMF caries index. (05 Mar 2000) |
| body mass index | One of the anthropometric measures of body mass; it has the highest correlation with skinfold thickness or body density. (12 Dec 1998) |
| buffer index | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
