What Is IV Cannula And Types of IV Cannula?

 

Cannula is a thin tube. This is a tube that doctors insert into a patient's body cavity, such as their nose, or into a vein. Doctors use them to administer medicine, drain fluid and provide oxygen.

You can use intravenous IV (IV) or nasal cannulas at home and in the hospital.

This article will explain what cannulas look like and the differences between nasal and IV Cannula. This article will also describe how to insert them and the risks involved.

What is a cannula?

A cannula (pronounced "CAN-you'la") is a thin tube doctors insert into a vein.

Common uses for IV cannulas are:

●      Blood transfusions and blood draws

●      Administration of medication

●      providing fluids

IV cannula types

There are many types of IV cannulas. These include:

Peripheral IV cannula

In the event of an emergency, surgery or radiological image, medical professionals may use peripheral IV canulas. These can be used to attach to an IV catheter for short-term use. To prevent it from moving, doctors tape the cannula to your skin.

Cannula for central line IV

A central line cannula may be used by medical professionals to administer fluids or medicine intravenously to patients who require long-term treatment. Someone undergoing chemotherapy might need an IV Cannula.

The central line IV cannulas are able to quickly deliver fluids and medication into the body through the jugular veins, femoral veins, or subclavian.

Draining cannulas

Draining cannulas are used by doctors to remove fluids and other substances from patients' bodies. These cannulas may also be used by doctors during liposuction.

A trocar is often surrounded by the cannula. Trocars are sharp, metal- or plastic instruments that puncture tissue to allow fluid removal from body cavities or organs.

Sizes and flow rates

There are many sizes of intravenous catheters. According to a 2015 study, the most popular sizes were between 14 and 22 gauge.

The gauge is smaller the smaller the cannula. Different sizes of cannulas allow liquid to flow through them at different rates. This is called flow rates.

A 14-gauge cannula can move approximately 269 milliliters of saline in one minute. A 22 gauge cannula is capable of passing 31 ml in just 21 minutes.
