Freevent® DualCare™ combines a speaking valve with the benefits of an HME
Speech is a very important way of communicating. To speak with a tracheostomy, you will need to redirect the air you breathe out to go up through your vocal cords. Freevent DualCare is a speaking valve which enables hands-free speech.
After a tracheostomy, you will no longer breathe through your nose and mouth, and air which is dry and too cold or too warm, enters your windpipe directly through the tracheostomy tube. HMEs can help compensate for these lost functions.
The HME ‘conditions’ the air you breathe by keeping it at a good humidity and temperature for your lungs to function properly.
Freevent DualCare combines a speaking valve with an HME, and in this way, enables hands-free speech and supports your lungs with important heat and moisture. The switch between the speaking mode and HME mode is done with 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 valve.
When you breathe out, the air is guided through your vocal cords and out through your mouth. 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 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.
An HME should be used day and night
It is very important to use an HME as much as possible. The Freevent DualCare system makes it possible for you to use an HME both day and night. In the daytime use the HME with Freevent DualCare Speaking Valve and with the HME DigiTop while you sleep.
IMPORTANT: Do not use the speaking valve during sleep since the airway could be blocked unintentionally. Use the HME DigiTop instead. Freevent DualCare Speaking Valve can only to be used with tracheostomy tubes if you have free passage for air through the upper airways.
