The water used in the flow meters for oxygen therapy is a potential source of fungal growth. What's the rationale for using bubbled oxygen? Is giving dry oxygen better than the humidified o2?

Rationale for humidified oxygen:
1.O2 therapy has a drying effect on the mucous membranes which when given for a prolonged period can result in airway damage.
2. Secretions can become thick and difficult to clear causing airway obstruction. 2/

So, Is humidified o2 better than dry o2?
It's not that simple.
For Low flow o2 therapy (<5L/min) humidification does not have any benefits as compared to dry o2.
For high flow o2 which is usually the case in covid humidified o2 prevents airway dryness.

Conclusion:
All patients requiring o2 > 4L/min, should be given humidified o2 and those requiring low flow o2 can do without humidification. 4/4
