What are the different sizes of the cannula?

Cannylae-or flexible tubes that can be inserted into the patient's body-with use for different purposes, leading to the size of the cannula that ranges from 14-22. Intravenous cannulas are used to administer drugs and other fluids to patients and to remove blood for sampling. The purpose of the patient and the urgency at which intravenous fluid must be delivered to which the cannula size must be used. The smaller the meter, the larger the cannula diameter and the faster flow of liquid. The different sizes of the cannula are marked with different colors, which makes it easier, especially in emergency situations in which the size can be critical. This size of the cannula is usually used for children because of their small size and for patients with veins that are difficult to channel, including patients with older and oncological patients. These cannulas are generally used only to infuse normal salt, antibiotics and anticoagulant drugs such as heparin.

Standard cannula for routine use is pink. The 20-meter cannula, has a fluid flow of 61 milliliters per minute. This cannula size is mainly used for routine blood sampling, but can also be used for routine blood transfusions and intravenous fluid infusion. Green cannulas are also considered a standard size. This cannula size, measurements such as 18 meters, with a fluid flow of 90 milliliters per minute, is used for routine blood transfusions, large volumes of fluid volumes, intravenous feeding of patients and collecting and separation of stem cells.

The size of the white -colored cannula is rarely. The 17-mock cannula has a fluid flow of 140 milliliters per minute. Examples in which these cannula size can be used for patients who require significant amounts of intravenous fluids or blood transfusions that, even if there are no extraordinary events, need to be given as quickly as possible.

Emergency Situations and Operational DivineAdla tends to use gray and brown cannulas. The gray color of the cannula is 16 measuring and fluid flow of 200 milliliters per minute and the brown-fired cannula with a 14-meter has a flow of 300 milliliters per minute. These larger sizes of the cannula are essential for rapid blood transfusion, intravenous fluids and drugs.

Choosing the right cannula size is important to make the treatment correctly. For example, the smaller sizes of the cannula result in greater pressure in the vein. This can cause hemoloysis during the aspiration of blood sample, if the cannula is too small. In addition, if the patient requires bolus or rapid infusion of drugs, too small cannula, which is too small, does not allow the liquid fast enough and combined joke increased pressure, can result in a vein blowing out of the vein.
