What is the minimum temperature required for active humidification through a heated humidifier?

Active humidification through a heated humidifier is essential in respiratory care, especially for patients requiring supplemental oxygen or mechanical ventilation. The correct choice indicates a temperature range of 33-44°C, which is optimal for creating effective water vapor without depleting moisture from the airways excessively.

At temperatures below 33°C, the capacity for the air to hold moisture is lower, which may lead to inadequate humidification and potential drying of the airway mucosa. Conversely, exceeding 44°C can risk overheating, which may cause damage to the airway tissues or discomfort to the patient.

Therefore, maintaining the temperature within the range of 33-44°C ensures that the delivered gas is properly humidified to match body conditions, assisting in maintaining mucociliary function and preventing complications. This temperature range effectively balances optimal moisture delivery while safeguarding the respiratory tract from thermal injury.
