Claim 16:
17. A tourniquet apparatus, comprising:
a cuff for encircling and applying a level of pressure to a limb of an individual patient;
a user interface adapted for selection by a user of a protocol symbol from a plurality of protocol symbols wherein each protocol symbol is indicative of a corresponding safety protocol that specifies a series of stored pressure levels, with each stored pressure level associated with stored time during a stored protocol time period, and wherein the user interface is further adapted to enable the user to adjust at least one stored time indicated by the selected protocol symbol within safe time limits associated with the selected protocol symbol;
a controller responsive to the series of stored pressure levels and the associated stored times specified by the safety protocol, after any adjustments by the user, and operable during the stored protocol time period for maintaining the level of pressure applied by the cuff to the individual patient near the series of stored pressure levels for each stored time associated with the stored pressure level;
a protocol hazard key adapted for manual actuation by the user to end the stored protocol time period at any time while the controller is operable if a hazard to the individual patient; and
a protocol safety interlock adapted to prevent selection of a second protocol symbol by the user while the controller is operable.
