A nasal cannula is a device that gives you additional oxygen (supplemental oxygen or oxygen therapy) through your nose. It's a thin, flexible tube that goes around your head and into your nose. There are two prongs that go inside your nostrils that deliver the oxygen. The tube is attached to an oxygen source like a tank or container. There are high-flow nasal cannulas (HFNC) and low-flow nasal cannulas (LFNC). The difference between them is in the amount and type of oxygen they deliver per minute. You may need to use a nasal cannula in the hospital or in another healthcare setting temporarily, or you may use a nasal cannula at home or for long-term use. It depends on your condition and why you need oxygen therapy.
Nasal cannulas are easy to apply and adjust, making them user-friendly for both patients and healthcare providers.
Cost-effective:Nasal cannulas are cost-effective compared to other oxygen delivery methods, making them a practical choice for patients requiring supplemental oxygen.

The average adult consumes around 7 or 8 liters of room air every minute while resting. Room air is usually made up of about 20% oxygen. If a person needs a little more air or oxygen, a nasal cannula might be used to deliver supplemental oxygen at higher percentages of up to 95%. Nasal Cannulas for Oxygen, most tubing can deliver up to 5 liters of oxygen per minute, which is the maximum amount of air flow that most people can handle comfortably. Too much supplemental oxygen can lead to dryness and nosebleeds. It' s also difficult to deliver more than 6 liters of air per minute because the additional airflow tends to "spew over" and only remains as active as producing 5 or 6 liters per minute.
Patients who require oxygen to self-respirate take air through a mask. Cannulas are frequently used with patients who might benefit from oxygen therapy but don' t have to have oxygen to breathe on their own. Stroke sufferers and other individuals who are impacted by vasoconstriction are examples of people who can benefit from oxygen delivered by nasal cannula. Special cannulas are installed in small, unpressurized aircraft to be used by pilots and passengers to boost oxygen levels during high altitude flights.
Traditionally, a high flow of oxygen can deliver highly accurate oxygen concentrations, but it is uncomfortable and inconvenient for many patients. Recently, humidifiers have started being used in conjunction with cannulas to help alleviate dryness, and wider tubing can be used to carry more than 6 liters of air per minute without drying out the nasal passages and reducing the incidence of nosebleed and asthma in patients. By humidifying respiratory gas, patients can receive high air flow volumes comfortably through a nasal cannula. This also frees up patients to eat, drink and continue other activities without being deprived of oxygen.
In other acute situations patients may need a higher concentration of oxygen and a non-rebreathe mask or simple oxygen mask is often used. Flow rates of 1-4 litres per minute are used with nasal cannulas, equating to a concentration of approximately 24-40% oxygen. Flow rates of up to 6 litres can be given but this will often cause nasal dryness and can be uncomfortable for patients. The advantages of nasal cannulas for patients who have chronic stable respiratory problems is that it is possible to eat, drink and talk while using them; they also reduce the risk of carbon dioxide rebreathing. Dry nasal passages can be a problem initially but with continued use this usually resolves itself.
A nasal cannula is generally used wherever small amounts of supplemental oxygen are required, without rigid control of respiration, such as in oxygen therapy. Most cannulae can only provide oxygen at low flow rates—up to 5 litres per minute (L/min)—delivering an oxygen concentration of 28–44%. Rates above 5 L/min can result in discomfort to the patient, drying of the nasal passages, and possibly nose bleeds (epistaxis). Also with flow rates above 6 L/min, the laminar flow becomes turbulent and the oxygen therapy being delivered is only as effective as delivering 5–6 L/min. The nasal cannula is often used in elderly patients or patients who can benefit from oxygen therapy but do not require it to self respirate. These patients do not need oxygen to the degree of wearing a non-rebreather mask. It is especially useful in those patients where vasoconstriction could negatively impact their condition, such as those suffering from strokes. A nasal cannula may also be used by pilots and passengers in small, unpressurized aircraft that do not exceed certain altitudes. The cannula provides extra oxygen to compensate for the lower oxygen content available for breathing at the low ambient air pressures of high altitude, preventing hypoxia. Special aviation cannula systems are manufactured for this purpose. With the introduction of nasal cannula which uses heated humidification for respiratory gas humidification, flows above 6 LPM have become possible without the associated discomfort, and with the added benefit of improving mucociliary clearance.
Nasal high-flow therapy
High flows of an air/oxygen blend can be administered via a nasal cannula to accurately deliver high volume of oxygen therapy. Respiratory gas humidification allows the high flows to be delivered comfortably via the cannula. Nasal high-flow therapy can be used as an effective alternative to face mask oxygen and allows the patient to continue to talk, eat and drink while receiving the therapy. Non-invasive delivery of oxygen air mixture delivered via a nasal cannula at flows that exceed the patient's inspiratory flow demands with gas that has been optimally conditioned by warming and humidifying the gas to close to 100% relative humidity at body temperature.
A nasal cannula is a thin, flexible tube that wraps around your head, typically hooking around your ears. On one end, it has two prongs that sit in your nose and deliver oxygen. The other end of the tube connects to an oxygen supply. There are several different types of oxygen supply delivery systems. The type of oxygen delivery system you use depends on your condition and what your healthcare provider recommends. Your healthcare provider also determines how much oxygen you need. The tubing attaches to an oxygen source and delivers a steady stream of medical-grade oxygen to your nose.
The oxygen concentration used with nasal cannulas is between 1 and 6 liters per minute. Your oxygen equipment. High-flow cannulas are available, but their output is similar to that of a continuous positive airway pressure system (CPAP). Your healthcare provider will calibrate your oxygen supply to the proper level for your needs. Nasal cannulas are less invasive than other oxygen delivery systems, most of which involve a face mask. In contrast, nasal cannulas generally don't prohibit regular eating and talking, and they are pretty portable.
It depends on your condition and the reason you need supplemental oxygen. Some people need it for the rest of their lives, while others need it while recovering from an illness or during a specific situation. For example, if your oxygen levels drop during childbirth, your provider may give you a nasal cannula for oxygen for just a few minutes. Others may depend on oxygen 24 hours a day or only when they sleep.
A nasal cannula can be high-flow or low-flow. A flow rate is a measurement of how much oxygen you' re getting through the cannula. It' s usually measured in liters. There' s a device on your oxygen supply that controls the flow of oxygen. High-flow nasal cannulas deliver warm oxygen. It can deliver up to about 60 liters of oxygen per minute. It delivers warm oxygen because oxygen at this flow rate could dry up your nasal passages quickly and lead to nosebleeds. Low-flow nasal cannulas don' t deliver warm oxygen. Because of this, they tend to dry out your nasal passages quicker. The flow rate for a low-flow cannula is up to about 6 liters of oxygen per minute. Remember, your healthcare provider recommends how much oxygen you need. It may seem like getting a high-flow cannula would be more efficient and give you more than enough oxygen. But getting too much oxygen has risks. Can you use a nasal cannula at home? Yes, a nasal cannula is a good option for at-home oxygen therapy.
