The IV cannula is very helpful in our life. A cannula is a tube that a medical doctor, nurse, or other person inserts into a patient’s nose or a physiological tube, such as the nose. Cannulas are used to deliver fluids, medicine, or oxygen. Cannulas can also be used to remove blood from the body. And the blood is also drained down.
What are the Different Types of cannulas?
There are two types of cannulas: the first and the second. Each type has several different subtypes.
1. IV cannula
IV CANNULA MEANS – “INTRA VENOUS CANNULA” Cannulas are small, flexible tubes that medical professionals place into veins to administer treatments and medical care. Medical professionals can use cannulas to administer medications, fluids, or blood by inserting them into the nose. Very easily and without causing any discomfort to the patient. The IV cannula is inserted into the vein at a 25⁰ – 30⁰ ANGLE.
Purpose of IV cannula:-
- Firstly for IV fluid replacement
- For blood transfusion
- For drug administration
- For collecting the blood sample
2. Nasal cannula
Cannulas are made of lacy tubing inserted inside the nose to deliver oxygen. Standard nasal cannulas have a lower oxygen flow than other cannulas, such as high-flow nasal cannulas (HFNC). HFNCs can also heat the gas to 98.6 F or 37 degrees Celsius. Warmer, more humidified air can facilitate easier breathing, while undesirable, dry air can cause airway inflammation.
What are type of IV cannulas?
Peripheral IV cannula – The peripheral IV cannula is the most widely used. It is used for almost all major surgeries and emergency cases and for those seeking radiological imaging. The use of the cannula is enormous.
Central line IV cannula – this type of IV cannula is used mostly for day-to-day treatments that involve the administration of normal fluids over several days so that the organism does not have to suffer much understanding.
They help in the immediate delivery of drugs that work very well to introduce a significant dose of blood or other substances into the body of patients.
This IV cannula is inserted into the femoral, Max Subbilariform, or Boulardi’s jugular vein.
Midline catheter – The midline cannula type is the best choice for individuals undergoing treatment for more than five days but less than one month.
These are more commonly used for blood transfusions or as they are considered a less invasive technique.

6. Easy Steps on How to insert an IV cannulas
1. Before you begin this procedure, you should prepare all the necessary items. This includes a sterile IV cannula kit, a scale, antiseptic nasal spray, a tourniquet, and an appliance label. This ensures that everything is ready.

4. Hold the cannula at an angle of 25 to 30 degrees angle and use controlled hands to insert the cannula into the vein. Make sure the slope is upwards so that there is minimal disturbance to the vessel.
5. Fix the cannula in place with preliminary tape and make sure it is secure but not too tight, allowing easy monitoring of air flow and the insertion site. Ensuring the length of the cannula is appropriate for good nutrition and benefits from acne. Learn more about patients
