Abstract
An inflatable blood pressure cuff is pressurized with a vapor which is produced by heating a fluid which has a boiling point between 290.degree. K. and 340.degree. K. with an electric heating element. The heating element may comprise a PTC resistor which is disposed within the fluid. A piezoresistive element may also be disposed in the fluid to detect pressure pulses associated with Korotkoff sound.
