What is the temperature of dial 3-5 of airway humidifier?

The temperature of dial 3-5 of airway humidification tank is 30-20 degrees Celsius. There is a set of native humidifier in the human body. When the outdoor air is too cold or too dry, the air will be heated and humidified by this humidifier and finally enter the lungs to complete the gas exchange. However, critically ill patients often establish artificial airway (tracheal intubation, tracheotomy intubation) and use ventilator to assist breathing to save lives, so the primary humidifier of human body loses its function. If critically ill patients want to keep the function of respiratory tract heating and humidification, this will enter our topic today: artificial airway humidifier.
