What is the consequence of delivering high concentrations of oxygen without humidification?

Delivering high concentrations of oxygen without humidification can lead to the drying of mucous membranes in the respiratory tract. When oxygen is administered at such levels, it can strip moisture from the mucosal surfaces lining the airways, which can result in irritation and discomfort. This can impede the protective mechanisms of the respiratory system, making it more susceptible to infection and other complications.

Proper humidification is important in oxygen therapy, as it helps maintain the natural moisture levels of the respiratory tract, ensuring that the mucous membranes stay hydrated and function effectively. Without this, patients may experience symptoms such as a dry throat, nasal congestion, or a decrease in overall airway comfort. Thus, the consequence of delivering high concentrations of oxygen without proper humidification is the drying of mucous membranes, highlighting the importance of incorporating humidification into oxygen therapy whenever necessary.
