🩺 MEDICAL TIP: IV CANNULA SIZES — WHICH ONE SHOULD YOU USE?
Not all IV cannulas are the same. Choosing the appropriate gauge can make IV access safer, more effective, and more comfortable for the patient.
🔵 14G–16G | Large Bore
➡️ Rapid fluid or blood administration
➡️ Major trauma & emergency resuscitation
➡️ Situations requiring high flow rates
🟢 18G | General Adult Use
➡️ IV fluids
➡️ Blood transfusion
➡️ Many emergency and surgical situations
🩷 20G | Common Clinical Choice
➡️ Routine IV medications
➡️ IV fluids
➡️ Suitable for many adult patients
🟡 22G | Smaller Veins
➡️ Elderly patients
➡️ Paediatric patients
➡️ Patients with fragile or difficult veins
🟣 24G | Very Small/Frail Veins
➡️ Neonates and infants
➡️ Very small or fragile veins
💡 Remember: A smaller gauge number means a larger cannula diameter and generally allows a higher flow rate.
