Many different diseases may require supplemental oxygen, such as asthma, COPD, cystic fibrosis, pneumonia and sleep apnea, which may require supplemental oxygen.

Many patients use nasal cannula to receive supplemental oxygen, but some prefer or need an oxygen mask. Nasal cannulas are generally more comfortable than oxygen masks and make it easier for patients to speak than to use masks. Compared to the use of a mask, the cannula takes up less space and can help patients reduce claustrophobia. Masks provide a more constant oxygen level (usually a preset amount) and can help control carbon dioxide retention and provide oxygen to the patient.

Oxygen naturally produces about 21% of indoor air, and any higher oxygen is considered a drug. Excessive oxygen can damage a patient's health and can cause a patient to become dependent on high levels of oxygen.

Nasal cannula

A nasal cannula is a device that delivers oxygen from an oxygen supply (ie, an oxygen canister, a portable oxygen concentrator) to a person in need of oxygen.

The lightweight test tube has two pins that are inserted in the nostrils, wrapped around the back of the ear and connected to an oxygen supply (such as an oxygen concentrator or a hospital wall).

In adults, a common use of nasal catheters is to carry 1-5 liters of oxygen per minute.

For those who may need more oxygen flow, the nasal cannula can also be high-flow oxygen, carrying up to 60 liters of oxygen per minute.

Nasal cannula can dry your nostrils, but some accessories can increase the moisture and heat in the air, making breathing easier.

Intubation is a good choice for people who often need oxygen but don't want to wear a mask.


Oxygen mask

The oxygen mask can be a mask/nasal mask or a full face mask.

The mask can be made of several materials such as plastic, rubber or silicone.

Medical oxygen masks are typically made of a polymer because it is soft and somewhat flexible.

 To secure the mask, an elastic strap is attached to either side of the mask and wrapped around the patient's head.

The average flow rate of a person using a mask is 6 to 10 liters per minute, and the percentage of oxygen is 40% to 60%.

A flow rate of at least 6 liters is required to help remove exhaled carbon dioxide for removal through the small holes in the side of the mask.

For those who retain carbon dioxide and need a little help to remove carbon dioxide, a mask is a good choice.


Like everything else, nasal cannulas and oxygen masks are also at risk.

Fortunately, these risks are not very serious and are considered low risk.

A common problem with nasal cannula is the risk of persistent nasal dryness and high oxygen levels, which can compromise a patient's health.

Some devices can be connected to the patient's oxygen supply to add moisture to the air, thereby reducing the irritation and dryness of the nasal passages.

A cannula or mask can cause skin irritation as it rubs against the skin.

This can be remedied by using an over-the-counter (or prescription) ointment that can help reduce bruising and skin irritation.

There is also a danger of fire because oxygen can promote combustion.

For people who use oxygen, posting a “No Smoking” sign nearby can minimize the possibility of fire.

Patients should ensure that their oxygen supply is kept away from sprays, candles, fireplaces and stoves.

Although oxygen may be beneficial, serious complications can still occur if the patient does not take the prescribed amount.

Pulmonary oxygen poisoning can occur when your body is getting too much oxygen, which can cause back pain or even coughing.

The average oxygen user who is set by the doctor at a rate of liters per minute is not at risk of oxygen poisoning.

If the patient's oxygen level is above the specified level, contact your doctor immediately if they notice any symptoms, such as itching during inhalation, burning, inhalation, cough and fever.

Future prospects for casing and masks

With the continuous development of medicine and science, people hope to have new and more comfortable ways to supply oxygen to people who need oxygen.

Currently, oxygen therapy can help many people who need oxygen supplements to improve their quality of life.

This will not only improve the quality of life, but also help them participate in activities, improve sleep, and even live longer than without oxygen.

Supplemental oxygen may also be prescribed during sleep or exercise, which may require the use of a cannula or mask to assist the patient in breathing during this time.


For those who use oxygen, nasal catheters and oxygen masks are common methods of delivering oxygen from a supply source. Both nasal cannula and oxygen masks are beneficial, depending on the doctor and patient to determine which is best for them.

There are also many risks associated with both delivery methods as they can damage your skin and nasal passages. Pulmonary oxygen poisoning is very dangerous, but if individuals take the prescribed liters of water per minute and follow them, they do not develop a risk of pulmonary oxygen poisoning.

Supplemental oxygen is very helpful to many people, providing them with the oxygen they need for their daily lives.
