| 1. An ultrasonic monitor for measuring pulse rate values in a living subject, comprising:
a) at least one source of ultrasonic energy;
b) a gel pad comprised of a thermoplastic elastomer and from about 50 to about 95% by weight of an ultrasound conductive diluent,
said gel pad is positioned to be directly between the energy source and the living subject, said gel pad is characterized
by having needle penetration from about 5 to about 300 (1/10 mm) according to ASTM D15;
c) an ultrasonic energy detector;
d) a microcontroller, responsive to the ultrasonic energy detector, which detects and calculates the pulse rate; and
e) a display unit, responsive to the microcontroller, which displays a readout of the pulse rate.
