Investigation of New Principles for Human Decompression Schedules Using Doppler Ultrasonic Blood Bubble Detection

Abstract

The development of doppler instrumentation for non-invasive detection of gas emboli moving through the arteries and veins is traced from its beginning in 1967 through 1974. The design and construction of the IEM and P precordial blood bubble detector is described in detail. The use of the doppler technique in the study and solution of decompression problems in divers is described.
