Oxygen Therapy

Oxygen therapy is a medical treatment that involves the administration of oxygen as a therapeutic agent to help increase oxygen levels in the body.

Indications

Methods of Administration

  • Nasal cannula: a tube that delivers oxygen directly into the nostrils
  • Face mask: a mask that covers the nose and mouth to deliver oxygen
  • Venturi mask: a type of face mask that uses a valve to control the flow of oxygen
  • Non-rebreather mask: a type of face mask that delivers high concentrations of oxygen
  • Hyperbaric oxygen chamber: a sealed chamber that delivers pure oxygen at higher-than-normal pressures

Benefits

  • Increases oxygen levels in the blood
  • Relieves shortness of breath and difficulty breathing
  • Reduces fatigue and weakness
  • Supports heart function
  • Aids in wound healing

Risks and Side Effects

  • Oxygen toxicity: high concentrations of oxygen can cause lung damage or other complications
  • Dryness of the nasal passages, mouth, and throat
  • Headaches
  • Nausea and vomiting
  • Increased risk of fire due to the presence of oxygen

Contraindications

  • Bleomycin therapy: a chemotherapy medication that can increase the risk of lung damage from oxygen therapy
  • Certain types of pneumonia, such as those caused by the bacteria Pneumocystis jirovecii

Monitoring and Maintenance

  • Pulse oximetry: a non-invasive test that measures blood oxygen levels
  • Arterial blood gas (ABG) analysis: a blood test that measures oxygen and carbon dioxide levels in the blood
  • Regular monitoring of oxygen flow rates and delivery systems to ensure safe and effective therapy
