Cannula size 14G

The cannula colour is Orange. It has a flow rate of 10.3l/hr for blood (240ml/minute), 16.2l/hr for plasma, and 13.5l/hr for crystalloids. The size is 45 mm.

How many times can you attempt cannulation?

If venepuncture or peripheral cannulation is unsuccessful after a maximum of 2 attempts (1 if the procedure is problematic) the health care professional must request a more experienced health care practitioner to undertake the procedure.
