Argon plasma coagulation - APCapplicator

WebArgon plasma coagulation (APC) is a noncontact method that allows for controlled electrocoagulation via high-frequency monopolar energy to be delivered to the tissue through an ionized gas (argon plasma). In a large retrospective study of 194 patients presenting with a visible vessel overlying an ulcer, APC was equally effective as … The calculations of PPT are done in the E-gauge, meaning that the laser field is taken as electromagnetic waves. The ionization rate can also be calculated in A-gauge, which emphasizes the particle nature of light (absorbing multiple photons during ionization). This approach was adopted by Krainov model based on the earlier works of Faisal and Reiss. The resulting rate is given by
