This procedure ill I use it for 22 years.Its not complicated.Hope it will help for someone of you with lot of mucus like its helpful for me.
In order to prevent to practice the drainage I have to beware of colds, cold drinks, wet clothes and cold weather. But when my nose starts to stream and crunch and my lungs fill with secretion this is the procedure I have to do:
1.Visit the doctor which prescribes me antibiotics and opens me a sick leave period. 2.In the pharmacy I buy Fluimucan (for expectoration) and assume it in the morning 3.During the day I drink a lot of liquids (water or tea). The liquid dilutes the secretion and allows easier expectoration. 4.I drink sage with milk and honey (to calm down the coughing) 5.Clean my lungs with drainage (if the secretion is forming fast I repeat the drainage every 2-3 hours if needed). 3 times a day should be ok.
Description of the drainage (see enclosed picture):

A bed with 4 pillows, massager and a bowl (for the secretion)

I lay on the pillows with my had down and my bottom high. I'm lying for about half an hour, sometimes longer. The longer, the better. I turn on the massager and put it on my both sides to shake in order to unstick the mucus (secretion) and facilitate it's moving toward the throat. When the secretion is in the throat I start to throw it out (see picture 3).

I turn myself aside and while the massager is shaking I'm inhaling deeply and exhaling slowly and extended. This way of breathing and expectoration allow the collecting of the secretion in the throat. When it comes in the throat just peak up the bowl and spit. When you feel that this side (that lung) is clean turn on the other side and repeat the whole procedure. It is very simple and very efficient. With no secretion in your breathing ways you have no impulse to cough and suffer less choking and feel much better. I do all that procedure by myself.

I just went to a youtube to look how its look like Flutter valvue and looks like acapella.But its not the same or?
Whats diffrent between flutter and acapella ? Do you use flutter and how long time it takes to throw mucus out.Thanks for replay
