Choosing a PIVC size
When choosing a PIVC and site, you should consider:
- The known or expected uses of cannula:
- For a patient receiving crystalloids, an 18-20 gauge cannula will suffice.
- For infusions of viscous fluids (eg. blood) and rapid infusions, a larger catheter such as a 14-16 gauge cannula is required.
- How long you expect the patient will need the cannula for
- The quality of the patient’s veins
- Any medical conditions the patient may have e.g. kidney diseases
