Camden COPD and Home Oxygen Service: HOS-AR

Add to CPD

Home oxygen therapy is used for the treatment of chronic hypoxaemia once any underlying disease management is optimised and all reversible causes have been identified and treated.

The multi-disciplinary Camden HOS-AR team consists of a combination of specialist respiratory physiotherapists and nurses with support from a respiratory consultant physician and access to specialist smoking cessation support.

The aims of the Camden HOS-AR team are to:

  • identify people appropriate for initiation of oxygen therapy 
  • initiate oxygen therapy safely and in line with local and national guidance
  • optimise benefit from oxygen therapy
  • reduce harm from trips, falls, smoking, fire and oxygen toxicity
  • maximise value from oxygen equipment use
  • improve patient and carer experience of having and using home oxygen.

The Camden HOS-AR team reviews:

  • all patients with a new home oxygen prescription within four weeks
  • all patients with home oxygen therapy (at least) once a year.
