Breathing in extra oxygen will increase the amount that is absorbed in the blood. This will have a beneficial effect on all the systems of the body that have suffered as a result of the lower oxygen levels.

With oxygen therapy you can expect the following improvements in your daily life.

• You may feel less breathless and better able to tolerate exercise
• Sleep better and feel less irritable
• Have more energy for everyday activities

The extra oxygen in the blood will improve the body's functions

• Increase oxygen delivery to the body thus reducing the work of the heart and the strain put on it
• Reduction in cardiac arrhythmias (irregular heart beats)
• Prevents excessive red blood cell production that would result in thicker blood and poorer flow through all blood vessels
• Reduces the deterioriation of pulmonary haemodynamics (blood flow to the lungs)
• Improves function of all the major organs due to better oxygen delivery
