摘要：
Microair bubbles in a bloodstream are diverted from the bloodstream in a diversion chamber by ultrasonic energy, and are collected in a blood-filled stasis column where they can be accurately measured by a bubble detector and then vented to atmosphere. Bubbles of different sizes can be separated into different stasis columns for enhanced measurement.
