Catheter choice may bias carotid baroreflex assessments; leaves open optimal equipment standardization in physiological studies.
Does the type of catheter (balloon-tipped vs fluid-filled) affect the recorded transmission of external neck pressure/suction to the carotid sinus in humans?
Transmission of external neck pressure/suction to the carotid sinus is higher than previously recorded and is significantly affected by equipment design and anatomical variation.
Querry et al. (2001) studied this question.
