Long Term Oxygen Therapy (LTOT)
Long Term Oxygen Therapy (LTOT) involves breathing in air that contains more oxygen (above 90% oxygen) than normal room air (21% oxygen) through a mask or tube connected to a device in your home. 3 ways of using LTOT are through:
- Oxygen Nasal Cannula: Short tubes placed in your nostrils
- Oxygen Mask: Mask cover your nose and mouth
- Tracheostomy Oxygen Mask: Some people may need a tube inserted into an opening made in the front of their neck (called tracheostomy) or a tube placed in their mouth and down their windpipe.

- Do not use flammable liquids, such as cleaning fluid, paint thinner or aerosols when using your device.
- Do not use oil-based emollients, such as vaseline, when using your device.
- Install fire alarms and smoke detectors in your home.
- Keep your device at least 3 meters away from any appliances that use an open flame, such as a gas cooker or gas fire.
