What is long -term oxygen therapy?
Long -term oxygen therapy uses stationary or portable devices to supply oxygen to patients with problems with breathing. Three types of long -term oxygen devices include compressed gas cylinders, liquid oxygen and oxygen concentrators that use electricity to convert the room to usable oxygen. Some patients with chronic obstructive pulmonary disease (COPD) use long -term oxygen therapy to prolong life.
This medical intervention can enable patients to improve quality of life and remain more active. Some patients report to facilitate depression caused by disorders that reduce breathing. Nevertheless, long -term oxygen therapy could be an emotional, physical and psychological challenges for patients in which it is difficult to use the equipment. Studies
show that some patients find that nasal cannulas used in long -term oxygen therapy, so users are less likely to followher prescribed treatment. Others could feel embarrassed when using a portable oxygen tanks in public or finding that they limit the usual activities. Patients using oxygen concentrators at home may also obey limited movement while connected to the machine.
According to research, not all patients suffering from COPD benefits from long -term oxygen therapy, especially people with mild or mild breathing problems. Scientists have found that oxygen therapy has prolonged life for some patients in these categories. In fact, this therapy could worsen inflammation associated with COPD by creating oxidative stress.
The gas cylinders store oxygen in the tanks under pressure. They are usually supplied to the patient's house for occasional use when it is difficult to breathe due to exertion. This form of long -term oxygen therapy may require frequent tank fillings and pose a risk of fire or explosion,If the patient smokes. May not be allowed on aircraft.
Liquid oxygen cylinders includes small containers that can be filled at home from larger devices that convert oxygen into liquid at an extremely cold temperature. This form of therapy is considered to be the most expensive, because oxygen could quickly evaporate from a larger tank, which requires frequent fillings. The device may be difficult for some patients to use, especially for seniors.
oxygen concentrators are connected to a standard home socket for oxygen insulation in the air. The flow can be adjusted to the level of the needed patient. These machines do not require fillings and supply a constant source of oxygen. Some oxygen -controlled oxygen concentrators can be allowed on commercial aircraft. This device may represent the least expensive method of long -term oxygen therapy.
