What is coefficient?

in the process of infusion, the number of drops per ml of solution is called the drip coefficient of the infusion set (GTT /ml)
at present, the commonly used drip coefficient is
10, 15 and 20
. The drop coefficient of disposable infusion set is indicated on the package as 20
according to the drop coefficient of the infusion set, the following formula can be deduced: the number of milliliters input per hour (ml /h) = (drops /min) × 60
min /h) /drop coefficient (drop /ml)
extended data
prone to problems
bacterial contamination: bacterial contamination in infusion is mainly due to serious pollution, incomplete sterilization, loose cork, looseness and air leakage in the production process. Pyrogen reaction: pyrogen reaction of infusion, mainly caused by pollution during use
the clarity and particle inspection are unqualified: compared with ordinary small volume injections, the volume of infusion is larger, and the risk of clarity and particle pollution is greater
there has been nursing since human beings. Nursing is people’s instinct and need for survival. In the struggle with nature, ancient people experienced the damage of beasts and the destruction of harsh natural environment, and self-protection became the first need. In the application of fire, Beijing ape man gradually realized that hot stones and sand can not only provide local heat, but also eliminate pain
primitive people created “Bian stone” and “stone needle” as tools to relieve pain. When human society developed to the era of matriarchal clan commune, the division of labor within the clan, men hunting, and women were responsible for managing the internal affairs of the clan, collecting wild plants and taking care of the old, young, sick and disabled. The rudiment of the family came into being
nursing symbolizes maternal love. The initial family or self-care consciousness has become the cradle of nurturing life and growth. It develops with human existence and human understanding of nature
the infusion dropping speed specified in basic nursing: 40

60 drops /min for adults and 20

40 drops /min for children. The default dropping coefficient of this speed is the infusion set of 15
according to the formula of infusion speed, the number of infusion drops can be adjusted to
drops /minute if the infusion set with a drip coefficient of 20 is replaced

when discussing mathematical problems, in expressions or equations related to specific variables (or unknown functions) and their derivatives, known functions or constants multiplied by unknowns are called coefficients. The term coefficient is also widely used in physics, engineering, computer technology and other aspects. For example, the ratio of the partial value of a quantity to the total value, or some relevant numbers in the relationship between the change of one quantity and the change of other quantities, are called coefficients. At this time, the coefficient is often preceded by the proper name of relevant phenomena or things, such as “expansion coefficient”, “carbolic acid coefficient”, etc. The number factor in a single term is also called the coefficient of this single term The factor of the highest power term in a polynomial is called the coefficient of the polynomial. Formula coefficient
14m 14
123x 123
(for example, the coefficient of 14m is 14. The coefficient of 123x is 123.) It is called the coefficient of the single term The sum of the exponents of all letters in a monomial is called its number For example, the coefficient of ABC is 1 and the number of times is 3 The coefficient of the primary term in the function relation y = x + 6 is the same as that in y = x, which is 1. Generally, the coefficient is not 0 If a polynomial contains an alphabetic term, the integer part of the term is called the coefficient of the term, and the term without every word is called a constant term. For example, in polynomial 4ab-5c + 6d-7, 4, – 5 and 6 are the coefficients of terms AB, C and D containing letters respectively, while – 7 does not contain letters, so it is called as a constant term. Note: if there is no numerical coefficient in the formula, it is 1 by default. The number of times refers to the number other than letters in the monomial formula

in Mathematics: when discussing mathematical problems, in the expressions or equations related to specific variables (or unknown functions) and their derivatives, the known functions or constants multiplied by unknowns are called coefficients. For example, the algebraic formula “3x”, which represents the product of a constant 3 and the unknown x, that is, 3 × x. Equal to x + X + X. “3x” represents a numerical value, which is only related to X. what is the relationship? “3” is to explain the relationship – the sum of three of them. Therefore, “coefficient” can be interpreted as “how many unknowns are there (additive sum).

in short, it is the number or letter before the integer (such as X, 2x + ay). For example, the coefficient of X is 1 In 2x + ay, 2 is the coefficient of X and a is the coefficient of Y.

is the ratio of two variables. Is a relatively constant quantity
