From the Guidelines

Oxygen concentrators are generally safer for smokers compared to oxygen tanks. Oxygen concentrators extract oxygen from the surrounding air and deliver it continuously without storing large amounts of oxygen, significantly reducing fire hazards 1. Oxygen tanks, which contain compressed oxygen under high pressure, pose greater risks for smokers because oxygen accelerates combustion and can cause severe, potentially fatal fires if a lit cigarette, ash, or ember comes near the oxygen source. Concentrators also eliminate the risk of tank explosions from physical damage.

Key Considerations

  • Smoking should be completely avoided when using any oxygen therapy, as it increases fire risk and compromises treatment effectiveness 1.
  • If a patient requires oxygen therapy and continues to smoke despite medical advice, healthcare providers typically recommend strict safety protocols: smoking outdoors only, at least 20 feet from the oxygen equipment, with the oxygen turned off for at least 10 minutes before smoking, and hands washed thoroughly afterward to remove residual oxygen 1.
  • The British Thoracic Society guidelines for home oxygen use in adults emphasize the importance of safety and risk assessment when prescribing oxygen to active smokers, including a home visit to assess the patient's home situation and attitude toward risks and smoking behavior 1.
  • Patients should be made aware of the dangers of using home oxygen within the vicinity of any naked flame, and should be instructed not to use oil-based emollients on their hands and face or inside their nose while using oxygen 1.

Recommendations

  • Smoking cessation is the safest approach, as continuing to smoke while using any form of oxygen therapy significantly increases fire risk and compromises treatment effectiveness 1.
  • Oxygen concentrators are preferred over oxygen tanks for smokers due to their reduced fire hazard and elimination of tank explosion risk.
  • Healthcare providers should recommend strict safety protocols for patients who continue to smoke despite medical advice, and should consider removing home oxygen therapy if there are clear safety issues or if the patient does not adhere to the prescribed oxygen therapy regimen 1.

From the Research

Safety Comparison of Oxygen Concentrators and Oxygen Tanks for Smokers

  • The safety of oxygen delivery devices for smokers is a significant concern, as smoking can increase the risk of fires and explosions when using oxygen therapy 2.
  • Oxygen concentrators are considered a safer option for smokers compared to oxygen tanks, as they do not store oxygen and therefore reduce the risk of fire or explosion 3, 4.
  • However, oxygen concentrators can be less reliable and may not provide a consistent flow of oxygen, which can be a concern for smokers who require a stable oxygen supply 5.
  • The use of oxygen concentrators can also be limited by access to electricity, which can be a challenge in low-resource settings 6.
  • Overall, while both oxygen concentrators and oxygen tanks have their advantages and disadvantages, oxygen concentrators are generally considered a safer option for smokers due to the reduced risk of fire and explosion.

Key Considerations for Smokers Using Oxygen Therapy

  • Smokers should be aware of the increased risk of fire and explosion when using oxygen therapy and take necessary precautions to minimize this risk 2.
  • Oxygen concentrators can be a safer option for smokers, but they require regular maintenance and monitoring to ensure they are functioning properly 3, 5.
  • Smokers should also be aware of the potential limitations of oxygen concentrators, including access to electricity and the need for regular maintenance 6.
  • Healthcare providers should carefully assess the individual needs of smokers requiring oxygen therapy and provide guidance on the safest and most effective option for their specific situation 3, 4.
