Which device is designed to increase the moisture content of supplemental oxygen?

• A. Humidifier
• B. Nasal Cannula
• C. Oxygen Mask
• D. Flow Meter

Answer: (A)

A humidifier is specifically designed to increase the moisture content of supplemental oxygen. When patients require oxygen therapy, especially for prolonged periods, the dry oxygen delivered can irritate the mucous membranes of the respiratory tract, leading to discomfort or complications. A humidifier introduces water vapor into the oxygen, which helps to keep the airways moist and can enhance patient comfort, improve mucociliary function, and reduce the risk of airway obstruction. In contrast, a nasal cannula is a device used to deliver supplemental oxygen to the patient but does not inherently add moisture to the oxygen. Similarly, an oxygen mask also delivers oxygen directly to the respiratory system without moisture enhancement. A flow meter is a device used to measure the flow rate of oxygen being administered, which, while critical for ensuring the appropriate amount of oxygen is provided, does not involve adding moisture to the oxygen itself. Thus, the humidifier is the only device specifically tailored for increasing moisture content in supplemental oxygen.
