Home Oxygen Therapy
Home oxygen therapy is usually recommended when the lungs are unable to supply enough oxygen to the blood. This condition is known as hypoxemia. This therapy increases the amount of oxygen in the blood, protects the heart, reduces shortness of breath, and prevents other cardiovascular problems. The air we breathe in, contains 21% oxygen whereas, the oxygen received at home with the help of the therapy, is close to 100% pure oxygen.
There are mainly three types of systems available to provide oxygen at home: liquid oxygen, compressed oxygen (tanks), and oxygen concentrators. Usually an oxygen mask or a nasal cannula (a two-pronged lightweight tube) is used to inhale oxygen.
