How is hypoxemia treated?

The treatment of hypoxemia primarily focuses on increasing blood oxygen partial pressure and saturation. The specific treatment methods are as follows: 1. Oxygen therapy: Includes oxygen administration via nasal cannula, face mask, non-invasive and invasive mechanical ventilation, aiming to increase arterial oxygen partial pressure and oxygen saturation, ensuring adequate tissue oxygen delivery. 2. Pharmacological therapy: Use of bronchospasm-relieving medications, such as aminophylline and dyphylline, to relax airway smooth muscles, relieve bronchospasm, and improve respiratory function. 3. Hyperbaric oxygen chamber therapy: In specific situations, such as CO poisoning, hyperbaric oxygen therapy may be used to enhance treatment effectiveness. 4. Etiological treatment: Addressing the underlying causes of hypoxemia, such as infection or airway obstruction, through appropriate interventions including anti-infective treatment and relief of obstruction.
