What treatment might be used to help control a patients blood oxygen level?

To help control a patient's blood oxygen level, supplemental oxygen therapy is commonly used. This can be administered through nasal cannulas, face masks, or more advanced devices like non-invasive ventilation or mechanical ventilators, depending on the patient's needs. Additionally, medications such as bronchodilators may be used to improve airway function and facilitate better oxygenation. Regular monitoring and adjustments to treatment can ensure optimal oxygen levels are maintained.
