Freevent DualCare combines a speaking valve with an HME
Freevent DualCare™ combines a speaking valve with a Heat and Moisture Exchanger (HME), and in this way enabling speaking and supporting your lungs with important heating and moisturizing. The switch between the speaking mode and HME mode is done extremely quickly and easily – just a simple twist of the lid of the speaking valve!
Freevent DualCare is put into speaking mode by twisting the lid of the speaking valve until it clicks into speaking mode position and the flexible membrane covers the openings of the speaking valve. When you breathe out, the air is guided through your vocal cords and out through your mouth. This way, the speaking valve makes it possible for you to speak. When Freevent DualCare is in speaking mode, there is no HME effect.
Freevent DualCare is put into HME mode by twisting the lid of the speaking valve until it clicks into position. In the HME mode, you breathe both in and out through the HME, saving heat and moisture when breathing out, and giving heat and moisture back when inhaling. When Freevent DualCare is in HME mode, speaking is not possible. In the HME mode, the breathing resistance is lower, compared to the speaking mode.
