Introduction
Under normal circumstances, the human body does not require pure oxygen to sustain life. The oxygen concentration in the air is already sufficient to meet the body's physiological needs. Medical oxygen is typically maintained within a specific concentration range—usually above 90% but not 100%. This level adequately meets patients' therapeutic requirements while minimizing the risk of oxygen toxicity.
Under normal circumstances, medical oxygen is not pure oxygen. The detailed explanation is as follows:
The human body does not require pure oxygen to sustain life under normal conditions. The oxygen concentration in the air is already sufficient to meet physiological needs. Medical oxygen typically maintains an oxygen concentration within a specific range—usually above 90% but not 100%. This level adequately meets patients' therapeutic requirements while minimizing the risk of oxygen toxicity. Prolonged inhalation of high-concentration pure oxygen, especially under pressures exceeding atmospheric pressure, may lead to oxygen toxicity, manifesting as lung damage, central nervous system dysfunction, and other symptoms. Therefore, using medical oxygen at an appropriate concentration better fulfills treatment needs while avoiding unnecessary risks.
When using medical oxygen, patients should follow medical instructions to adjust oxygen flow rate and concentration, and avoid making adjustments independently. Pay attention to bodily responses during oxygen therapy, and promptly inform healthcare providers of any adverse reactions. Keep the oxygen delivery equipment clean and dry to prevent contamination or damage.
