How is humidity typically added to an oxygen delivery system?

Adding humidity to an oxygen delivery system is commonly achieved through the use of a humidifier or bubbler apparatus. These devices are specifically designed to ensure that the oxygen delivered to the patient is adequately humidified, which helps to prevent the drying of airway mucosa that can occur when high-flow oxygen is provided without moisture.

A humidifier works by creating water vapor that mixes with the oxygen as it moves from the delivery system to the patient. This is crucial, especially when supplying oxygen for extended periods, as it supports mucosal health and enhances comfort during oxygen therapy.

While other methods, such as controlling room temperature or using a sterile water bottle, may add some moisture, they are not standard practices for effectively humidifying medical oxygen. Ventilation systems typically do not introduce moisture deliberately into oxygen delivery systems, as they focus on air circulation and filtration rather than hydration. The use of a dedicated humidifier or bubbler remains the most reliable and efficient method for adding humidity in these scenarios.
