TYPES OF OXYGEN THERAPY
- Continuous oxygen therapy : In later stages of emphysema this is the only therapy that can prolong survival. It is usually recommended when lung oxygen level PO2 (partial pressure of oxygen) is below 55 mm/Hg or SaO2 (saturation of oxygen) less than or equal to 88% while the patient is resting or less than 60 mm/ Hg if the patient has right heart failure.
- Non-continuous oxygen therapy : Patient with less severe COPD may require supplemental oxygen only if, for example, the patients PO2 falls below 55 mm/Hg while exercising.
The amount of oxygen to be taken by the person is prescribed by the treating physician according to the patients’ requirement.
