A report detailing the operation of a 5 MHz Doppler ultrasonic bubble detector developed for use in detection of venous gas emboli formed in the blood of divers during decompression as well as for monitoring craniotomies, cardiopulmonary bypass equipment and other medical procedures where there is danger of aeroembolism. A precordial sensor employing 12 inch square resonant transmitting and receiving crystals separated by 2 cm and focused 2-7 cm retrosternal is employed for the detection of all gas emboli returning in the weins to the right heart and lungs, the precordial sensor being positioned to the left of the midsternal border over the pulmonary artery and right ventricle. Additional monitoring of the peripheral vasculature through the use of specialized probes is also described. Author
