Oxygen therapy

Oxygen, essential for all bodily energy processes, is pivotal in maintaining normal bodily functions. Administration of oxygen is recommended for all forms of pulmonary hypertension.

This treatment alleviates hypoxia and subsequently reduces vasoconstriction (narrowing) of small vessels. Oxygen therapy stands out as a paramount life-saving approach for pulmonary hypertension, involving the inhalation of pure oxygen to address cellular-level oxygen deficiency.

Unlike many contemporary therapeutic methods, oxygen therapy is entirely safe, as oxygen has virtually no contraindications and does not induce allergic reactions. It's crucial to recognize that patients with pulmonary hypertension often necessitate long-term or even lifelong oxygen therapy, typically administered through inhalation.

For extended oxygen therapy at home, oxygen concentrators are frequently employed. These devices operate on the principle that ordinary atmospheric air under pressure is directed to a "molecular sieve" composed of inorganic silicate beads (zeolite). Zeolite captures nitrogen molecules, allowing oxygen molecules to pass through.

Consequently, the concentration of oxygen at the air flow's exit from the device significantly increases. The oxygen percentage at a flow rate within the range of 0.5 - 5 liters per minute can reach 90-95%. A mixture of oxygenated gas is delivered to the respiratory tract through nasal cannulas. As these cannulas do not entirely obstruct nasal passages, patients breathe both ambient air and oxygen from the concentrator.

Depending on the flow rate, oxygen delivered via nasal cannulas may cause dryness in the nose, leading to irritation and occasional nosebleeds. The use of oxygen humidification minimizes this issue.

Portable oxygen concentrators offer additional convenience outside the home, providing immediate relief for patients. Equipped with high-capacity batteries, these devices are lightweight, and their low noise levels enhance their usability.
