Publication number: 20240017034Abstract: An expiratory limb is provided that is configured to remove humidified gases from a patient and configured to provide improved drying performance by providing a tailored temperature profile along the limb. Limbs for providing humidified gases to and/or removing humidified gases from a patient are also provided, the limbs having improved gas residence time at constant volumetric flow rate. The improved residence time can be achieved by providing a limb comprising multiple lumens.Type: ApplicationFiled: June 12, 2023Publication date: January 18, 2024Inventors: Robert Andrew David Milne, Timothy Dee Gierke

Publication number: 20230052731Abstract: A drying expiratory limb of a breathing circuit is provided that is configured to increase or optimize drying of a gas to reduce or prevent condensation. The drying expiratory limb can include a wall that is at least partly made of a breathable material configured to allow transmission of water vapor but substantially prevent transmission of liquid water. The wall includes first and second openings in the wall, the openings respectively configured to receive a gas at a first temperature and a first relative humidity and to allow the gas to exit having a second temperature and a second relative humidity. The drying expiratory limb can be configured to tailor the temperature drop of the gas along the wall to maintain a relative humidity within a targeted range and/or to maintain the gas temperature above its dew point temperature.Type: ApplicationFiled: June 29, 2022Publication date: February 16, 2023Inventors: Robert Andrew David Milne, Timothy Dee Gierke
