Over 15% of Canadians aged 65 or older are living with COPD
COPD causes breathlessness and affects the quality of life. As symptoms get worse a person may be unable to perform daily activities and can become dependent upon other people. In the later stages, a COPD patient may need oxygen daily to be able to breathe. Not only physical but mental health also gets impacted and it can cause severe depression and anxiety.
Most Stage-IV COPD patients require more oxygen. But it can also be used if the patient notices greater shortness of breath or if the oxygen level in their blood falls below 90% on a regular pulse oximeter. Right-sided heart failure can be avoided with enough oxygen.
According to the Canadian Lung Association (CLA), carbon monoxide levels are cut in half compared to smokers after quitting smoking for eight hours. Therefore, if you stop smoking, your breathing will significantly improve within 2–7 months.
