Bubble Humidifier
At high flow rates and with prolonged oxygen therapy it can be helpful to use humidifiers.
Some wards will have bubble bottle humidifiers like the one on the right / below.
Current BTS guidelines advise against their use because of a lack of evidence for their benefit. However, many patients find them helpful.
The guidelines recommend using nebulised normal saline instead.
