pulmonary hypertension oxygen therapy

Oxygen therapy for pulmonary arterial hypertension (PAH) is a crucial treatment approach that can typically enhance patients' blood oxygen saturation, alleviate symptoms of breathlessness, and potentially improve their quality of life and survival rates.

In the management of PAH, oxygen therapy helps correct hypoxemia by supplying additional oxygen, which in turn reduces pulmonary vascular resistance and improves cardiac function. Patients with mild PAH may only require intermittent oxygen therapy, whereas those with moderate to severe PAH may need continuous oxygen therapy. The objective of oxygen therapy is to maintain the patient's blood oxygen saturation above 90%. Furthermore, for certain specific types of PAH, such as that caused by chronic obstructive pulmonary disease (COPD), oxygen therapy can also enhance patients' exercise tolerance and overall quality of life.

It is important to recognize that while oxygen therapy is beneficial for PAH patients, it does not cure the condition nor replace other treatment modalities, including pharmacological therapy. Therefore, patients undergoing oxygen therapy must also adhere to their physician's recommendations for comprehensive treatment. Additionally, patients must be cautious when using oxygen therapy to avoid potential risks associated with excessively high oxygen concentrations, such as oxygen toxicity. Proper use of oxygen therapy equipment, under the guidance of a physician, and regular monitoring of blood oxygen levels are essential to ensure the safety and efficacy of oxygen therapy.
