What is oxygen therapy?
Oxygen therapy is a medical treatment that involves administering oxygen to a person who has low levels of oxygen in their blood. It is commonly used to treat a range of medical conditions that can cause hypoxemia (low oxygen levels), such as lung diseases like chronic obstructive pulmonary disease (COPD), pneumonia, and asthma, as well as heart failure and sleep apnea.
The therapy involves providing supplemental oxygen through a variety of methods, such as using an oxygen concentrator, oxygen tanks or cylinders, or a portable oxygen concentrator. The oxygen is delivered through a nasal cannula, face mask, or other device, and the amount and delivery method of oxygen used depends on the person's individual needs and condition.
Oxygen therapy can improve a person's oxygen levels, reduce symptoms such as shortness of breath, and improve overall quality of life. However, it is important to use oxygen therapy only under the guidance of a healthcare professional, as too much oxygen can be harmful to the body.
Who needs oxygen therapy?
Oxygen therapy is typically recommended for people who have low levels of oxygen in their blood, a condition known as hypoxemia. Hypoxemia can be caused by a variety of medical conditions, such as:
• Chronic obstructive pulmonary disease (COPD)
• Pneumonia
• Asthma
• Respiratory distress syndrome (RDS) in premature infants
• Heart failure
• Sleep apnea
• Pulmonary fibrosis
• Lung cancer
• Cystic fibrosis
In addition to these conditions, oxygen therapy may be recommended for people who are undergoing certain medical treatments, such as mechanical ventilation, or for people who are in high-altitude environments where the air is thin and contains less oxygen.
The decision to use oxygen therapy and the method of delivery will depend on the individual's medical condition, severity of hypoxemia, and other factors. It is important to consult with a healthcare professional before beginning oxygen therapy to determine the appropriate treatment plan.
What does oxygen therapy do?
The main goal of oxygen therapy is to increase the amount of oxygen in the body and improve oxygen delivery to the organs and tissues. Oxygen therapy can help to:
● Improve oxygen levels in the blood:
By providing supplemental oxygen, oxygen therapy can increase the amount of oxygen in the blood, which can improve overall organ and tissue function.
● Reduce shortness of breath:
People with lung or heart conditions may experience shortness of breath, which can be alleviated with oxygen therapy.

The location of oxygen therapy will depend on the individual's medical condition, severity of hypoxemia, and other factors, and will be determined by a healthcare professional.
What are the types of oxygen therapy systems?
There are several types of oxygen therapy systems that can be used to deliver supplemental oxygen to people who have low levels of oxygen in their blood. These include:
● Oxygen concentrators:
These are electrically powered devices that take in air from the surrounding environment and filter out nitrogen and other gases to produce concentrated oxygen. Oxygen concentrators are often used in home settings and can provide a continuous supply of oxygen.
● Compressed oxygen tanks:
These are tanks filled with compressed oxygen that can be delivered to a person's home or used in hospital or clinic settings. They can provide a continuous or intermittent supply of oxygen, depending on the flow rate prescribed by the healthcare provider.
● Liquid oxygen systems:
These systems store oxygen in liquid form in a portable tank. The oxygen is converted from liquid to gas form as it is used, and the system can provide a continuous supply of oxygen for several hours.
● Oxygen masks and nasal cannulas:
These are devices used to deliver oxygen from an oxygen source directly to the person's airways. Masks cover the nose and mouth, while nasal cannulas are small tubes that fit into the nostrils. The flow rate of oxygen can be adjusted to meet the individual's needs.
● Portable oxygen concentrators:
These are lightweight, battery-powered devices that can be used to deliver oxygen on-the-go. They are often used by people who require oxygen therapy while traveling or participating in physical activity.
The type of oxygen therapy system used will depend on the individual's needs and medical condition, as well as factors such as mobility and lifestyle. Your healthcare provider can help determine which system is best suited for your needs.
How do oxygen therapy systems deliver oxygen?
Oxygen therapy systems deliver supplemental oxygen in several ways, depending on the type of system and the individual's needs. Here are some common methods of oxygen delivery:
■ Continuous flow:
Oxygen is delivered continuously through a nasal cannula or oxygen mask at a prescribed flow rate. This is often used for people who require a constant supply of oxygen, such as those with chronic obstructive pulmonary disease (COPD) or other respiratory conditions.
■ Pulse dose or demand flow:
Oxygen is delivered in short bursts (pulses) during inhalation, rather than continuously. This type of delivery is often used with portable oxygen concentrators or liquid oxygen systems, and is useful for people who require oxygen during physical activity or while sleeping.
■ High-flow nasal cannula:
This is a specialized nasal cannula that delivers a high flow of humidified oxygen. It is often used in hospital settings to treat respiratory failure or to help wean people off mechanical ventilation.
■ Non-invasive positive pressure ventilation (NIPPV):
This involves the use of a mask or nasal cannula that delivers pressurized oxygen to the airways to improve oxygenation and reduce work of breathing. NIPPV is often used in hospital settings for people with acute respiratory failure or exacerbations of COPD.
■ Mechanical ventilation:
This involves the use of a machine that delivers oxygen to the lungs through an endotracheal tube or tracheostomy. Mechanical ventilation is used in hospital settings for people with severe respiratory failure who require assistance breathing.
The method of oxygen delivery will depend on the individual's needs and medical condition, as well as the type of oxygen therapy system being used. Your healthcare provider can help determine which method of oxygen delivery is best for you.
What are the benefits of oxygen therapy?
Oxygen therapy can provide several benefits for people with low levels of oxygen in their blood, including:
