| frame | 1. To construct by fitting and uniting the several parts of the skeleton of any structure; specifically, in woodwork, to put together by cutting parts of one member to fit parts of another. See Dovetail, Halve, v. T, Miter, Tenon, Tooth, Tusk, Scarf, and Splice. 2. To originate; to plan; to devise; to contrive; to compose; in a bad sense, to invent or fabricate, as something false. "How many excellent reasonings are framed in the mind of a man of wisdom and study in a length of years." (I. Watts) 3. To fit to something else, or for some specific end; to adjust; to regulate; to shape; to conform. "And frame my face to all occasions." (Shak) "We may in some measure frame our minds for the reception of happiness." (Landor) "The human mind is framed to be influenced." (I. Taylor) 1. Anything composed of parts fitted and united together; a fabric; a structure; especially, the constructional system, whether of timber or metal, that gives to a building, vessel, etc, its model and strength; the skeleton of a structure. "These are thy glorius works, Parent of good, Almighty! thine this universal frame." (Milton) 2. The bodily structure; physical constitution; make or build of a person. "Some bloody passion shakes your very frame." (Shak) "No frames could be strong enough to endure it." (Prescott) 3. A kind of open case or structure made for admitting, inclosing, or supporting things, as that which incloses or contains a window, door, picture, etc.; that on which anything is held or stretched; as: The skeleton structure which supports the boiler and machinery of a locomotive upon its wheels. A molding box or flask, which being filled with sand serves as a mold for castings. 4. <machinery> A term applied, especially in England, to certain machines built upon or within framework; as, a stocking frame; lace frame; spinning frame, etc. 5. Form; shape; proportion; scheme; structure; constitution; system; as, a frameof government. "She that hath a heart of that fine frame To pay this debt of love but to a brother." (Shak) "Put your discourse into some frame." (Shak) 6. Particular state or disposition, as of the mind; humor; temper; mood; as, to be always in a happy frame.

| anaesthesia, closed-circuit | Inhalation anaesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anaesthetic gas and oxygen are added so that no anaesthetic escapes into the room. Closed-circuit anaesthesia is used especially with explosive anaesthetics to prevent fires where electrical sparking from instruments is possible. (12 Dec 1998) |
| closed anaesthesia | Inhalation anaesthesia in which there is total rebreathing of all exhaled gases, except carbon dioxide which is absorbed; gas flow into the anaesthetic circuit consists only of oxygen, in amounts equal to the patient's metabolic consumption, plus small amounts of other gases (e.g., nitrous oxide) which undergo continued uptake by and distribution in the patient.

| closed-angle glaucoma | angle-closure glaucoma |
| closed bite | <dentistry> A malocclusion where your upper teeth cover your lower teeth when you bite down. This is also called a deep bite. (08 Jan 1998) |
| closed chain compound | Any compound in which the constituent atoms, or any part of them, form a ring. Used mainly in organic chemistry where: 1) numerous compound's contain rings of carbon atoms (carbocyclic compound's) or carbon atoms plus one or more atoms of other types (heterocyclic compound's), usually nitrogen, oxygen, or sulfur; 2) where the atoms in the ring are all of the same element (homocyclic or isocyclic compound); 3) where the ring is saturated or contains nonconjugated double bonds (alicyclic compound), the compound is similar in properties to the corresponding acyclic compound (e.g., cyclohexane resembles hexane); 4) where the ring contains conjugated double bonds in a closed loop in which there are 4n + 2 (where n is an integer) delocalised π electrons (Huckel's rule) (aromatic compound; e.g., benzene, pyridine), it is more stable than the corresponding saturated ring and exhibits unusual chemical properties characteristic of itself and not of other types of rings or of acyclic compound's. These aromatic compounds have the ability to sustain an induced ring current. Synonym: closed chain compound, ring compound. (05 Mar 2000) |
| closed chest massage | Rhythmic compression of the heart between sternum and spine by depressing the lower sternum backward with the heels of the hands, the patient lying supine. Synonym: external cardiac massage. (05 Mar 2000) |
| closed circle | A circuit for administration of an inhalation anaesthetic in which there is complete rebreathing with carbon dioxide absorption. (05 Mar 2000) |
| closed circuit method | A method for measuring oxygen consumption in which the subject rebreathes an initial quantity of oxygen through a carbon dioxide absorber and the decrease in the volume of oxygen being rebreathed is noted. (05 Mar 2000) |
