Meaning of cannula
A cannula is a flexible tube that can be inserted into the body. For medical use, there are 11 different types of cannulas. The most commonly used are intravenous and nasal cannulae.
A nasal cannula is used to deliver low levels of oxygen to a patient who needs supplemental oxygen.
An intravenous cannula is used to give medical personnel access to a patient’s vein for fluid withdrawal or insertion of medications or other fluids. It is commonly called IV. Typically, the IV cannula is capped with a trocar or needle, which is used to create an opening in the body through which the tube is threaded.
A cannula can be inserted into the veins of the hand.
To insert an IV, a medical professional will first place a tourniquet around their patient’s arm to keep blood in the arm. Once the veins in your hands and arm are filled, you will clean the area around the injection site and insert the trocar into a filled vein.
The cannula will be pushed over the needle and into the vein before the needle is removed and the tube is secured to the skin with medical tape.
There are four main complications that can come from the insertion of an IV. A hematoma is a bruise that occurs as a result of poor tube placement. Infiltration is what happens when the tube is inserted under the skin, but not into a vein.
An embolism occurs when air travels down the tube into the vein, or if a part of the cannula breaks and travels down the bloodstream. Phlebitis is inflammation of the vein that holds the tube.
An intravenous cannula allows medical professionals to access a patient’s vein for the insertion of medications or other fluids.
A nasal cannula is used to deliver low levels of oxygen to a patient who needs supplemental oxygen. It is equipped with a horseshoe-shaped tip at one end that is inserted into the patient’s nose, and a flexible band that is secured around the patient’s head to keep the cannula in place.
The other end of the tube is connected to a tank or other type of oxygen supply system. Before a patient receives a nasal cannula, their vital signs will be checked. You will be monitored while receiving oxygen to make sure you are comfortable and that the oxygen levels in your body are increasing.
Nasal cannulae are designed to fit into the nose and secure around the head.
There are few complications and side effects associated with the use of a nasal cannula. Patients may experience some dryness in the nose as a result of the flow of oxygen. Nasal cannulas are not just for patients. They are also used by aviators who need supplemental oxygen when flying at high altitudes.
A cannula is usually secured to the body with medical tape. A person receiving supplemental oxygen should carefully monitor their blood saturation level with a pulse oximeter.
The cannulas can be used as biopsy needles. A medical professional will place a tourniquet around a patient’s arm before inserting an intravenous cannula.
