Procedures for Doppler Ultrasonic Monitoring of Divers for Intravascular Bubbles

Abstract

Doppler ultrasonic detection of intravascular bubbles is a routine procedure for several laboratories engaged in decompression research. This technical communication recommends standard procedures to be followed in using the Doppler technique. The choice of monitoring sites is discussed. The two cases for observation, rest and movement, are described, and recommendations for scheduling the observations are given. Hints for making good, well-documented tape recordings of the Doppler signal are included. The K-M Code for describing the results is explained, and recommendations for the information that should be stored in records are given. Some difficulties in interpreting signals are discussed.
