Defining Anesthesia •The word anesthesia originated from the Greek term anaisthaesia, meaning “insensibility”; is used to describe the loss of sensation to the body in part or in its entirety. This variation is related to providers’ anesthetic gas selections – specifically, higher use of desflurane in the United States. 60 (dogs), 100 (cats); exceptions can include preanesthetic bradycardia, drugs causing a lower heart rate, and stimulation of the vagus nerve. Cylinder sizes are designated according to letters, with size ‘A’ being the smallest; size ‘E’ (E- tank) is commonly used on anesthesia machine.
