Correlation between Carotid Doppler Metrics during Blood Loss and Resuscitation

journal of medical ultrasound

This analysis demonstrates correlation between carotid artery corrected flow time and velocity time integral in a model of haemorrhage. The strength of the correlation increases with the number of consecutive cardiac cycles averaged.
