Most people need oxygen to survive. Our bodies require oxygen for cells to produce energy. However, some individuals require supplemental oxygen due to various health conditions. Let's explore who might need additional oxygen.
Who Needs Supplemental Oxygen?
Many medical conditions can cause the body's oxygen levels to drop below what's necessary for proper function. Supplemental oxygen therapy helps these individuals improve their oxygen levels. Here are some examples:
-
Respiratory Diseases: Conditions like chronic obstructive pulmonary disease (COPD), emphysema, asthma, bronchitis, and cystic fibrosis significantly impair lung function, reducing oxygen intake. Supplemental oxygen becomes essential for managing these conditions.
-
Infections: Severe infections such as COVID-19 can lead to acute respiratory distress and low blood oxygen levels, necessitating supplemental oxygen. Pneumonia is another example.
-
Heart Failure: When the heart is unable to pump blood efficiently, oxygen delivery throughout the body is compromised. Supplemental oxygen can alleviate this problem.
-
Sleep Apnea: Individuals with sleep apnea may experience periods of interrupted breathing during sleep, leading to low blood oxygen levels. Supplemental oxygen can be beneficial during sleep.
-
Other Conditions: Other conditions that might require supplemental oxygen include high altitude exposure, certain congenital heart defects, and some severe anemias.
Specific Oxygen Needs: The level and duration of supplemental oxygen required vary greatly depending on the individual's condition, severity, and overall health. A doctor will determine the appropriate oxygen therapy regimen for each patient.
Low blood oxygen levels (hypoxemia) are dangerous and can lead to organ damage. Supplemental oxygen therapy increases the amount of oxygen in the blood, improving overall health and reducing symptoms such as shortness of breath, fatigue, dizziness, and even depression.
The need for supplemental oxygen is determined through medical assessment including blood oxygen level measurements (often using pulse oximetry) and arterial blood gas tests. These tests measure how much oxygen is in your blood. If these levels are consistently low, a doctor may prescribe supplemental oxygen.
For example, when oxygen saturation falls below 89 percent, or arterial oxygen pressure falls below 60 mmHg, supplemental oxygen is often considered necessary.
