THE LOSS OF SEVOFLURANE FROM A CLOSED BREATHING SYSTEM

When volatile anaesthetics are used in a closed breathing system it is usually assumed that inflow of anaesthetic to the system matches upta ke by the patient. Early laboratory reports on the interactions betwee n sevoflurane and soda lime cast doubt on that assumption We have meas ured the loss of sevoflurane, desflurane and isoflurane from a closed breathing system and found no differences of consequences.
