The name comes from blocking—"choking"—high frequencies while passing low frequencies. It is a functional name; the name "choke" is used if an inductor is used for blocking or decoupling higher frequencies, but the component is simply called an "inductor" if used in electronic filters or tuned circuits.

For homogeneous fluids, the physical point at which the choking occurs for adiabatic conditions is when the exit plane velocity is at sonic conditions; i.e., at a Mach number of 1. [ 1 ] [ 2 ] [ 3 ] At choked flow, the mass flow rate can be increased only by increasing the upstream density of the substance.
Some anti-choking devices can also be used to solve choking. This procedure has modifications for infants (babies under 1 year-old) , for the people with problems in the belly as the pregnant or too much obese people , for the disabled victims in wheelchair , for the victims that lay on the bed but are unable to sit down , and for the victims ...
