Effect of left paratracheal pressure on left carotid blood flow
Main finding · PSV in the left common carotid arteryResult — go to the resultMean PSV difference −15.30 cm s-1 95% CI −31.09 to 0.48Authors' conclusion
Our results suggest that LPP does not have a significant effect on carotid blood flow in individuals without a carotid pathology.
Study context
