Electrical conductivity of tissues

Definition

Electrical conductivity of tissues refers to the ability of biological tissues to conduct electrical currents, which is influenced by their composition, structure, and water content. Understanding this property is crucial for the application of medical plasmas, as it affects how these plasmas interact with the body's tissues during treatments, influencing factors such as energy absorption and treatment efficacy.

5 Must Know Facts For Your Next Test

1. Tissues with higher water content, such as muscle and blood, generally have greater electrical conductivity compared to fatty tissues.
2. The conductivity of tissues can vary significantly depending on factors like temperature, frequency of the applied electric field, and the presence of electrolytes.
3. Medical plasmas generate ionized gas that can enhance tissue conductivity, potentially improving therapeutic effects during treatment.
4. Understanding tissue conductivity helps in designing effective plasma-based therapies by optimizing parameters like frequency and power levels for better treatment outcomes.
5. Changes in tissue conductivity can indicate pathological conditions, making it a useful parameter for diagnostic purposes in medical applications.

Review Questions
