A neutral plasma coagulator is an energy source that produces pure plasma to provide coagulation.Why is patient risk reduced with this directed energy source?
A) The plasma is formed from activated carbon dioxide, an inert gas.
B) The plasma approximates tissue with a low heat welding process.
C) No electrical current passes through the patient.
D) The coagulation results in minimal tissue eschar.

Patient risk is reduced because no electrical current passes through the patient.Plasma is created when a low flow of argon gas is excited within the handpiece,consisting of an anode (where current enters)and cathode (where current exits).The gas,in the plasma state,emerges from the handpiece tip as an electrically neutral pale blue jet stream that coagulates tissue.When the plasma reaches bleeding tissue,it releases its kinetic energy as heat and causes coagulation of the bleeding surface as well as cutting capabilities.Because the electrodes are contained within the handpiece,no dispersive pad is used.
