 ==Introduction==
 Blood pressure (BP) is a useful measurement to help assess the cardiovascular status of a patient during an anaesthetic, or as a diagnostic test for an underlying cause of ocular changes in cats as a result of systemic high blood pressure. Bear in mind that in a conscious animal, a stress free environment is useful in preventing a rise in blood pressure which is induced by anxiety, particularly in cats. Many agents used during anaesthesia have an affect on the cardiovascular system, and blood pressure in particular so it is important to monitor sequential readings and correct BP changes if necessary. Some surgical procedures such as portosystemic shunt surgery, for example may have a direct effect on blood pressure and BP must be closely monitored throughout the procedure.

 ===Doppler Flow Detection===
 Method:
-#Usually measured using the metacarpal and metatarsal artery, although the tail can also be used.
+#Usually measured using the metacarpal and metatarsal artery, although the base of the tail can also be used.
 #Once a pulse has been detected, the doppler probe is placed in that position on the limb to check that it is audible and the probe can then be taped to the limb.
 #A cuff is selected and placed proximal to the doppler probe and attached to a manometer.
