Summary

Long term oxygen therapy (LTOT) for chronic respiratory failure offers limited survival benefits. Further research is needed to improve patient selection and find additional treatments for progressive airway disease.

Area of Science:

  • Pulmonary Medicine
  • Respiratory Care

Background:

  • Long term oxygen therapy (LTOT) is a treatment for chronic respiratory failure in patients with obstructive airways disease.
  • Patient selection and treatment efficacy for LTOT vary significantly across different countries.

Purpose of the Study:

  • To review the current status of LTOT for home use in chronic respiratory failure.
  • To evaluate the benefits and limitations of LTOT and identify areas for future research.

Main Methods:

  • Review of existing literature and clinical practices regarding LTOT.
  • Analysis of patient selection criteria, including basic arterial blood gas measurements and additional physiological criteria.
  • Assessment of survival benefits and clinical outcomes associated with LTOT.

Main Results:

  • LTOT demonstrates a limited survival benefit of approximately five years.
  • Current evidence does not support the use of additional physiological criteria for patient selection, as they have not shown prolonged survival or clinical benefit.
  • Oxygen concentrators are the most cost-effective method for oxygen administration in home settings.

Conclusions:

  • While LTOT adequately treats hypoxemia, it does not halt the progression of obstructive airway disease, which remains the ultimate cause of death.
  • Further research is essential to refine patient selection criteria and explore adjunctive therapies to manage progressive airway obstruction.
  • There is an ongoing need for research and audit of LTOT, particularly for home-based treatments.
