When should I use my oxygen?
You should only use ambulatory oxygen when you are moving about and exerting yourself. This includes when walking around the shops and if participating in exercise.
You should not use it when you are sitting still and resting.
Are there any risks or side effects?
Side effects include:
- a dry mouth/nose. You can use KY Jelly or Aqua gel to moisten your nose. You must not use products such as Vaseline as these are flammable and can cause burns.
- minor nosebleeds can occur. If this is persistent please contact us.
Never use flammable products, such as cleaning fluid, paint thinner, petroleum based creams or aerosols, while you are using oxygen (or for 20 minutes afterwards).
Do not smoke or allow others to smoke whilst you are using oxygen, this also includes vaping. You also need to be aware of open flames, anything that may create a spark or generate heat and not use oxygen around them.
We will discuss the risks with you before prescribing oxygen.
Signs and Symptoms of carbon dioxide retention
Some people who require supplementary oxygen can be at risk of retaining carbon dioxide. It is important to be aware of the signs and symptoms and what to do if you notice any of them. These include:
• headaches
• lethargy
• drowsiness
• confusion
If you notice any of these symptoms whilst using your oxygen, remove it immediately and contact your health professional, who may ask you to make an appointment for a blood test in the chest clinic.
Will I be seen again?
If you are prescribed ambulatory oxygen you will receive:
• a 4 week safety visit at home
• 3/6/12 month follow up as discussed with your clinician
This is important as your oxygen requirements may change.
