In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables. For example, in.

In neurocardiogenic syncope, blood pressure rapidly falls, and blood flow to the brain becomes very low. The person loses consciousness (passes out or faints), usually for only a few seconds.
