Speaking mode
The Speaking Valve is put in speaking mode by rotating the
lid until it clicks into the speaking mode position (the fl exible
membrane covers the openings of the lid). In speaking mode
the membrane only opens when you breathe in. It is closed
when you breathe out, so you will breathe out through your
mouth and nose, and you will be able to speak. You may feel
a somewhat higher breathing resistance in speaking mode
than in HME mode due to the membrane. You can now try to
speak some words, beginning with low volume and pressure.
HME mode
The Speaking Valve is put in HME mode by rotating the lid
until it clicks into the HME mode position (i.e., the fl exible
membrane does NOT cover the openings of the lid). HME
mode allows you to both breathe in and out through the HME,
thereby conditioning the inhaled air.
Note that increased mucus production may appear during
the fi rst weeks of HME use.
With Speaking Valve Blue (REF 7755), the colored membrane
makes it easier to see whether the valve is in speaking mode
or in HME mode.
2.3 Insertion and usage of HME DigiTop
and HME DigiTop O
Assemble and insert the speaking device as described in 2.1.
If you use the HME DigiTop O
disassemble the oxygen tubing while the device is disconnected
from the trach-tube. This is to avoid uncomfortable movement
of the trach-tube.
Make sure that the oxygen tubing is securely attached; it
should be assembled beyond the conical edge (Figure 15).
If you have not used HMEs previously, you should be aware
that the device may increase breathing resistance to some extent.
When you occlude the two holes on the sides with your
fi ngers, exhaled air will be redirected through your upper airways
and you will be able to speak (Figure 11). Releasing the fi nger
occlusion will allow you to inhale again through the device.
The two openings in the HME DigiTop / HME DigiTop O
allow you to breathe in and out through the device, thereby
conditioning the inhaled air continuously.
Note that increased mucus production may appear during
the fi rst weeks of HME use.
