Ellie Doppler and Dee Dee Echo:
Two more pics I drew for my June presentation at work about the use of noninvasive tests for detecting pulmonary emboli (blood clots in the lungs).
Ellie Doppler is named after L.E. (lower extremity) Dopplers, a test used to detect clots in the leg vessels. Compression Devices (like on her legs) are used to prevent such clots.
Dee Dee Echo is named after the 2D Echo, an ultrasound test of the heart.
