Oxygen therapy is a medical treatment that involves the administration of supplemental oxygen to patients who have low levels of oxygen in their blood, a condition known as hypoxemia. It is commonly used to treat individuals with chronic respiratory conditions, such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, asthma, and acute conditions like pneumonia, heart failure, or after major surgeries. Oxygen therapy helps to ensure that the body's tissues and organs receive adequate oxygen for proper function. Depending on the severity of the oxygen deficiency, oxygen can be delivered through various devices, including nasal cannulas, oxygen masks, and transtracheal oxygen (a tube inserted into the windpipe). For long-term use, portable oxygen concentrators or liquid oxygen systems allow for mobility, making it easier for patients to carry on with daily activities. In more severe cases, oxygen tanks or non-invasive ventilators may be used. The goal of oxygen therapy is to maintain blood oxygen levels within a healthy range to reduce strain on the heart, improve overall energy levels, and prevent complications associated with low oxygen, such as organ damage or cognitive decline. It is essential for patients to follow a healthcare provider’s instructions for use to avoid potential risks, such as oxygen toxicity or fire hazards.
