The Importance of Oxygen Therapy for Hypertensive Patients

    Hypertension is a common chronic condition, and long-term uncontrolled high blood pressure can lead to severe complications such as cardiovascular diseases and kidney damage. In the management of hypertension, in addition to medication and lifestyle interventions, oxygen therapy has gradually gained attention as an adjunctive treatment.

一. The Relationship Between Hypertension and Hypoxia

1. The Impact of Hypertension on Blood Vessels

   Prolonged hypertension causes thickening of blood vessel walls and reduced elasticity, thereby affecting blood flow and oxygen delivery. Impaired endothelial function can lead to localized tissue hypoxia, particularly in vital organs such as the heart, brain, and kidneys.

2. The Impact of Hypoxia on Blood Pressure

   Hypoxia stimulates the sympathetic nervous system, leading to increased heart rate and vasoconstriction, which further raises blood pressure. Additionally, hypoxia can trigger oxidative stress and inflammatory responses, exacerbating vascular damage.

二. The Mechanisms of Oxygen Therapy

1. Improving Tissue Oxygen Supply

   Oxygen therapy increases oxygen levels in the blood, alleviating tissue hypoxia and reducing the burden on the heart and blood vessels. For hypertensive patients, especially those with cardiovascular diseases, oxygen therapy can help relieve symptoms and lower the risk of complications.

2. Reducing Sympathetic Nervous System Excitability

   Oxygen therapy can inhibit the overactivation of the sympathetic nervous system, reducing vasoconstriction and heart rate, thereby helping to lower blood pressure.

3. Alleviating Oxidative Stress and Inflammation

   Hypoxia is a significant trigger for oxidative stress and inflammation. Oxygen therapy improves oxygen supply, reduces free radical generation, protects endothelial function, and slows the progression of hypertension.

三. The Potential Benefits of Oxygen Therapy

1. Reducing Blood Pressure Fluctuations

   Oxygen therapy can help stabilize blood pressure, reducing fluctuations and thereby lowering the risk of cardiovascular events.

2. Improving Quality of Life

   For hypertensive patients with symptoms of hypoxia, oxygen therapy can alleviate breathing difficulties, fatigue, and other symptoms, enhancing quality of life.

3. Slowing Disease Progression

   By improving tissue oxygen supply and reducing vascular damage, oxygen therapy may help slow the progression of hypertension and its complications.

As an adjunctive measure in hypertension management, oxygen therapy plays an important role in improving tissue hypoxia, reducing blood pressure fluctuations, and slowing disease progression.
