Water humidifiers are vital in oxygen therapy systems, especially in oxygen cylinders and concentrators for the following.

• Addition of moisture: Oxygen therapy often involves delivering dry oxygen, which can cause dryness and irritation in the airways, throat, and nose. Water humidifiers add moisture to the oxygen flow, helping to prevent these issues and making the therapy more comfortable to the user.
• Protection of the mucous membrane : Dry air can lead to the drying out of mucous membranes in the respiratory tract, making them more susceptible to irritation, inflammation, and infection. Water humidifiers help maintain the natural moisture levels in the respiratory tract, thereby protecting the mucous membranes and reducing complications.
• Oxygen Effectiveness: Humidified oxygen is often more effective in promoting gas exchange in the lungs compared to dry oxygen. The moisture in the oxygen helps to keep the airways open and facilitates the transfer of oxygen into the bloodstream, improving the overall therapy effectiveness.
• Reduction of Nasal Irritation: Dry oxygen can cause discomfort, nasal dryness and nose bleeding in s particularly those patients who require high-flow oxygen therapy. Water humidifiers help alleviate these symptoms by adding moisture to the oxygen, making the therapy more tolerable and reducing the risk of nasal irritation.
• User Comfort: Humidified oxygen is generally more comfortable to breathe, especially for long-term oxygen therapy patients who rely on oxygen continuously. By maintaining adequate moisture levels in the oxygen stream, water humidifiers contribute to user compliance with therapy.
