  • Shortness of breath, difficulty breathing, or a worsening cough
  • Restlessness and discomfort
  • Chest pain or tightness
  • Fast/racing pulse rate

  • Asthma
  • Lung cancer
  • Chronic obstructive pulmonary disease (COPD)
  • Flu
  • COVID-19
  • Other chronic illnesses which affects breathing

How does Oxygen Therapy help these patients?

Patients with breathing issues have lower oxygen levels in their bodies and oxygen therapy will help to reduce the strains on the heart, brain, and muscles.

Oxygen therapy is usually not necessary unless the SpO2 level of patient is less than 92%. Unless indicated by doctors, patients with SpO2 level more than 92% will not require oxygen therapy. Nurses can initiate oxygen therapy for the  patients if their SpO2 level breach the expected normal parameters of oxygen saturation.

This treatment will have no beneficial effects on healthy patients.

Are there any side effects to Oxygen Therapy?

Oxygen Therapy is generally safe, but it can cause some side effects. These include a dry or bloody nose, tiredness, and morning headaches.
