"F-wave study " uses supramaximal stimulation of a motor nerve and recording of action potentials from a muscle supplied by the nerve.
2.
The compound muscle action potential ( CMAP ) size is found using supramaximal stimulation of the motor nerve to the muscle or muscle group ( similar to a nerve conduction study ).
3.
The MAC is the concentration of the vapour ( measured as a percentage at 1 atmosphere, i . e . the partial pressure ) that prevents patient " movement " in response to a supramaximal stimulus ( traditionally a set depth and width of skin incisions ) in 50 % of subjects.
