Electrical safety standards Electrical safety standards Electrical safety is a system of organizational measures and technical means to prevent harmful and dangerous effects on workers from electric current, electric arc, electromagnetic field and static electricity. The electrical safety develops with the technical progress. In 1989 OSHA promulgated a much-needed regulation in the General Industry Regulations. Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. In 1994 were established Electrical Safety Foundation International non-profit organization dedicated exclusively to promoting electrical safety at home and in the workplace. Standards are compared with
Electrical cardiometry Electrical cardiometry Electrical cardiometry is a method based on the model of "Electrical Velocimetry", and non-invasively measures stroke volume (SV), cardiac output (CO), and other hemodynamic parameters through the use of 4 surface ECG electrodes. Electrical cardiometry is a method trademarked by Cardiotronic, Inc., and is U.S. FDA approved for use on adults, children, and neonates. The measured bioimpedance over time can be expressed as the superposition of three components: where Z is the quasi-static portion of the electrical impedance (base impedance), ΔZ are the changes of impedance due to the respiratory cycle, and ΔZ are the changes of impedance
