During thermal ablation, how are endobronchial ignitions prevented?
a. The FiO2 should always be maintained at 21%.
b. The FiO2 should always be maintained below 40%.
c. The procedure is only performed for 3 sec at a time.
d. The patient's airway is cooled with cryo-therapy prior to the procedure.
ANS: B
During the application of "hot therapies" (thermal ablation) like laser, electrosurgery, or argon plasma coagulation, the FiO2 should always be maintained below 40% to prevent endobronchial ignition.
