| impedance | 1. Total opposition to flow. When flow is steady, impedance is simply the resistance, e.g., the driving pressure per unit flow; when flow is changing, impedance also includes the factors that oppose changes in flow. Thus, deviations of impedance, from simple ohmic resistance because of the effects of capacitance and inductance, become more important in alternating current as the frequency of oscillations increases. In fluid analogies (e.g., pulsatile flow of blood, to-and-fro flow of respiratory gas), impedance depends not only on viscous resistance but also upon compressibility, compliance, inertance, and the frequency of imposed oscillations. 2. Resistance of an acoustic system to being set in motion. (05 Mar 2000) |

| impedance angle | A term expressing the ratio of electric resistance to electric capacitance (ohms to microfarads) in the tissues of the body or any other substance. (05 Mar 2000) |
| impedance method | A method for localizing brain structures by measuring impedance of electric current. (05 Mar 2000) |
| acoustic impedance | The resistance that a material offers to the passage of a sound wave (colloquial); a property of a medium computed as the product of density and sound propagation speed (characteristic acoustic impedance). Discontinuities in acoustic impedance are responsible for the echoes on which ultrasound imaging is based. Unit: the rayl. (05 Mar 2000) |

| acoustic impedance tests | Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance). (12 Dec 1998) |
| cardiography, impedance | A type of impedance plethysmography in which bioelectrical impedance is measured between electrodes positioned around the neck and around the lower thorax. It is used principally to calculate stroke volume and cardiac volume, but it is also related to myocardial contractility, thoracic fluid content, and circulation to the extremities. (12 Dec 1998) |
| plethysmography, impedance | Recording changes in electrical impedance between electrodes placed on opposite sides of a part of the body, as a measure of volume changes in the path of the current. (12 Dec 1998) |
| electric impedance | The opposition to the flow of an alternating current, which is the vector sum of ohmic resistance plus additional resistance, if any, due to induction, to capacity, or to both. (12 Dec 1998) |

acoustic impedance is the resistance of a medium to the propagation of sound, and is largely a function of density and the speed of sound in the medium. In a slightly different sense, it is a measure of the resistance of an interface to the propagation of sound from one medium to the next. See The Ear.
