Heated humidifiers play a significant role in patient care for several reasons. Firstly, they enhance patient comfort by providing warm, moist air, which is less irritating to the respiratory tract than cold, dry air. Secondly, they help in maintaining the integrity of the respiratory mucosa, thereby reducing the risk of airway inflammation and pulmonary complications. Lastly, they are essential in the management of patients requiring long-term respiratory support, as they help in reducing hospital stays and improving overall outcomes.
