After wearing the speech valve, the patients can recover their voice and speech communication functions in varying degrees immediately.

After wearing the speech valve, the patients can recover their voice and speech communication functions in varying degrees immediately. Speaking valves are closed single-channel valves. When inhaled, the valves open and the end-inspiratory valves close automatically. There is no need to reverse the flow of gas and secretions through the chest to close the valves. There is no leakage detected in the use, which can be used indefinitely in theory, but the manufacturer recommends one-time use.
Preparations for the use of speech valves:
1. Assessment and Family Education
(1) Evaluate the indication of the valves. The evaluation scale is detailed in the valves evaluation table.
(2) Explain fully to patients and their families, such as the principle of speaking valves, possible situations and treatment.
2. Check whether the inner diameter of endotracheal cannula is the same as that of speech valve device.
In foreign countries, they are all standard fittings and seldom coincide with each other at home. The usual improvement method is to take out the inner sleeve and enlarge the outer diameter by winding with non-woven paper tape after disinfection.
