"' 4-Iodopropofol "'is a drug derived from the commonly used sedative anaesthetic agent, propofol . 4-Iodopropofol has similar effects to propofol on isolated receptors, acting primarily as a GABA A positive modulator and sodium channel blocker, but when given to animals it has only anxiolytic and anticonvulsant effects, lacking the strong sedative-hypnotic profile of propofol.

It can also be seen that a plenum vaporizer can only work one way round : if it is connected in reverse, much larger volumes of gas enter the vaporising chamber, and therefore potentially toxic or lethal concentrations of vapour may be delivered . ( Technically, although the dial of the vaporizer is calibrated in volume percent ( e . g . 2 % ), what it actually delivers is a partial pressure of anaesthetic agent ( e . g . 2kPa ) ).
