How would I determine the accurate priming volume for the Cannon Catheter after the hub has been replaced or the catheter has been trimmed at some point other than the cut line?
If the catheter is cut at some point other than the cut line, the priming volume will need to be adjusted. For every centimeter cut away from the trim line, the priming volume changes by 0.13 cc. To determine the new priming volume for each 1 cm the catheter is trimmed proximally (towards the catheter hub) from the trim line, the arterial and venous priming volumes should be increased by 0.13 cc. For each 1 cm the catheter is trimmed distally (away from the catheter hub) from the trim line, the arterial and venous priming volumes should be decreased by 0.13 cc.
