Long Term Oxygen Therapy

Long Term Oxygen Therapy

Long Term Oxygen Therapy (LTOT) is a medical treatment in which supplemental oxygen is provided to patients who have chronic low oxygen levels in their blood due to lung diseases such as chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), pulmonary hypertension, or severe heart conditions. LTOT helps improve oxygenation, reduces the workload on the heart, enhances energy levels, and improves overall quality of life. It is prescribed for patients with persistent hypoxemia (low blood oxygen) even at rest or during minimal activity.

LTOT is typically administered using oxygen concentrators, portable oxygen cylinders, or liquid oxygen systems, allowing patients to maintain mobility and independence. Therapy duration may range from several hours during the day to continuous use, depending on medical recommendations. Proper training, adherence, and regular monitoring are essential to ensure safety and effectiveness. With long-term oxygen therapy, patients often experience improved survival rates, better sleep, reduced complications, and enhanced daily functioning.

Care & Management of LTOT

• Use oxygen exactly as prescribed by your doctor
• Ensure proper flow rate and duration of oxygen use
• Keep oxygen equipment clean and well-maintained
• Avoid open flames, smoking, or flammable materials near oxygen
• Monitor oxygen saturation regularly
• Check for skin irritation from nasal cannulas or masks
• Maintain hydration and lung hygiene
• Follow-up with pulmonologist for adjustments
• Educate family and caregivers on safe oxygen use
• Maintain backup oxygen supply if needed
