A transcutaneous electrical nerve stimulation (TENS or TNS) is a device that produces mild electric current to stimulate the nerves for therapeutic purposes.TENS, by definition, covers the complete range of transcutaneously applied currents used for nerve excitation, but the term is often used with a more restrictive intent, namely, to describe the kind of pulses produced by portable ...
Transcutaneous pacing is accomplished by delivering pulses of electric current through the patient's chest, which stimulates the heart to contract. [ citation needed ] The most common indication for transcutaneous pacing is an abnormally slow heart rate .
Transcutaneous oxygen measurement (TCOM or TcPO 2) is a non-invasive method of measuring the oxygen level of the tissue below the skin. Since oxygen is carried by the ...
Transcutaneous pacing (TCP), also called external pacing, is recommended for the initial stabilization of hemodynamically significant bradycardias of all types. The procedure is performed by placing two pacing pads on the patient's chest, either in the anterior/lateral position or the anterior/posterior position.
External devices work by transcutaneous stimulation and do not require surgery. Electrical impulses are targeted at the vagus nerve in the neck, or aurical (ear), at points where branches of the vagus nerve have cutaneous representation.
Neurostimulation is the purposeful modulation of the nervous system's activity using invasive (e.g. microelectrodes) or non-invasive means (e.g. transcranial magnetic stimulation, transcranial electric stimulation such as tDCS or tACS).

This is followed by introduction of a flexible "introducer guide wire" to define the pathway through the skin and into the passageway or "lumen" of the blood vessel. The needle is then exchanged for an " introducer sheath " which is a small tube that is advanced over the introducer guide wire and into the blood vessel.
