Understanding Oxygen Therapy Needs

Home oxygen therapy is prescribed when your body isn’t getting enough oxygen naturally through breathing. Oxygen helps maintain healthy cell function, energy levels, and organ health. Doctors usually recommend it after evaluating your oxygen saturation levels (SpO₂) with a pulse oximeter or through an arterial blood gas (ABG) test.

Common Conditions That May Require Oxygen at Home:

• COPD (Chronic Obstructive Pulmonary Disease)

• Post-Surgery Recovery

• Sleep Apnea or Chronic Hypoxemia

• COVID-19 or Pneumonia Recovery

• Interstitial Lung Disease, Asthma, or Heart Failure

  
  

Signs you may need oxygen therapy at home include:

• Persistent shortness of breath even at rest

• Fatigue or brain fog

• Bluish tinge in lips or fingertips

• Oxygen saturation consistently below 88–90%
