| saturation | 1. The act of saturating, or the state of being saturating; complete penetration or impregnation. 2. <chemistry> The act, process, or result of saturating a substance, or of combining it to its fullest extent. 3. <optics> Freedom from mixture or dilution with white; purity; said of colours. The degree of saturation of a colour is its relative purity, or freedom from admixture with white. Origin: L. Saturatio: cf. F. Saturation. Source: Websters Dictionary (01 Mar 1998) |

| saturation analysis | General term for an assay in which a binder competes for labelled versus unlabelled ligand; following separation of free and bound ligand, the ligand (the analyte assayed) is quantitated by relating bound and unbound ratios to known standards. See: enzyme-linked immunosorbent assay, radioreceptor assay, immunoassay, enzyme-multiplied immunoassay technique, radioimmunoassay. Synonym: displacement analysis, saturation analysis.

| saturation index | An indication of the relative concentration of haemoglobin in the red blood cells, calculated as: grams of haemoglobin per 100 ml (expressed as percent of normal) ÷ haematocrit value (expressed as percent of normal) = saturation index The normal index for adults and infants is 0.97 to 1.02; in primary and secondary anaemia, the index is usually considerably less than 0.97.

| saturation of receptors | Saturation, the state in which all receptors are effectively occupied all the time, can be said to occur in a simple binding equilibrium when the concentration of ligand is more than 5 times the Kd value, although strictly this will only be true at infinite ligand concentration.

| secondary saturation | A technique of nitrous oxide anaesthesia consisting of an abrupt curtailment of the oxygen in the inhaled mixture to produce a deep plane of anaesthesia, following which oxygen is administered to correct hypoxia. (05 Mar 2000) |
| anaesthesia recovery period | The period of emergence from general anaesthesia, where different elements of consciousness return at different rates. (12 Dec 1998) |
| recovery | 1. A getting back or regaining; recuperation. 2. Emergence from general anaesthesia. 3. In nuclear magnetic resonance, refers to relaxation. Origin: M.E., fr. O.Fr. Recoverer, fr. L. Recupero, to recover, get back, fr. Re-, again, + capio, to take (05 Mar 2000) |
| recovery boiler | A pulp mill boiler in which lignin and spent cooking liquor (black liquor) is burned to generate steam. (05 Dec 1998) |
| recovery room | Hospital unit providing continuous monitoring of the patient following anaesthesia. (12 Dec 1998) |
| recovery score | A number expressing the condition of an infant at various stipulated intervals greater than 1 minute after birth and based on the same features assessed by the Apgar score at 60 seconds after birth. (05 Mar 2000) |
| materials recovery facility | A recycling facility for municipal solid waste. (05 Dec 1998) |
| resource conservation and recovery act | (RCRA) A federal law regulating solid and hazardous waste. RCRA governs the generation, storage, treatment, transport, and disposal of hazardous waste. (05 Dec 1998) |
| creep recovery | The time-dependent portion of the decrease in strain in a material or object following removal of the stress that has deformed it. (05 Mar 2000) |
| product recovery | The process of separating a desired recombinant protein from the growth medium and the other elements in the host cells in which it was grown. (14 Nov 1997) |
