What is the role of humidifiers in oxygen therapy?

Humidifiers play a crucial role in oxygen therapy by preventing the drying of mucous membranes. When a patient receives supplemental oxygen, particularly at high flow rates or in arid environments, the oxygen can be very dry, which may lead to irritation and dehydration of the respiratory mucosa. This can cause discomfort and increase the risk of complications such as infections or airway obstruction.

By adding moisture to the oxygen delivered to the patient, humidifiers help maintain the hydration of the mucous membranes in the airways. This is essential for keeping the cilia functioning well, which helps clear mucus and debris from the respiratory tract, ultimately leading to better respiratory health and comfort for the patient. Regular use of humidifiers in oxygen therapy is vital, especially for patients who may have prolonged exposure to high concentrations of dry oxygen.
