What condition could result from inadequate humidification in a patient on mechanical ventilation?

Inadequate humidification in a patient on mechanical ventilation can lead to dehydration. When patients are mechanically ventilated, especially for extended periods, the air delivered through the ventilator can be very dry. The respiratory system relies on properly humidified air to keep the airways and lung tissue moist. Without adequate humidity, the mucosal surfaces in the airways can become dehydrated. This can result in thickened respiratory secretions, impaired mucociliary function, and an increased risk of airway obstruction and infection.

Dehydration in this context specifically refers to the loss of water from the respiratory tract and can lead to complications such as increased work of breathing and reduced effectiveness of clearances, ultimately impacting ventilation and overall respiratory function.
