  • A RESPIRATORY HUMIDIFYING DEVICE AND A METHOD OF OPERATION
    Publication number: 20240157081
    Abstract: Described is a respiratory humidifying device comprising: a moisture exchanger positioned in a respiratory system having an inspiration and expiration respiratory cycle, the moisture exchanger positioned such that airflow occurring in the inspiration and expiration respiratory cycle is in contact with the moisture exchanger, the moisture exchanger being temperature-responsive and having a critical solution temperature; a heater; and a controller controlling a supply of power to the heater such that: the heater causes the moisture exchanger temperature to rise to or above a first target temperature by about a first target point in the respiratory cycle; and the moisture exchanger temperature falls to or is below a second target temperature by about a second target point in the respiratory cycle, wherein the first target temperature is above the second target temperature, and wherein during inspiration moisture is added to the incoming air and during expiration the moisture exchanger extracts moisture from the
