Help to get tyler an airway clearance vest/machine

What do you see in the pic. A happy healthy child. Unfortunatly looks can be decieving. Tyler was born with a genetic life limiting condition called cystic fibrosis. It is a a prgressive condition in wich a faulty gene causes the body to produce extra thick sticky mucus in the lungs digestive system and other organs. 
The extra thick mucus can cause increased number of lung infections that can be particularly harder to clear and slowly causing progressibe irreversable lung damage and inevatably a shorted life.
Tyler has to endure daily physio and nebulisers to help keep his airways clear and nasty bugs at bay.
A high frequency chest oscilation vest is a method of air way clearance that can be used alongside other methods to help keep the chest as clear as possible. However they are not funded on the nhs due to lack of evidence on effectivness and a higj price tag. Although there is a lack of noted evidence i have seen this piece of eqiupment help families amazingly with clearing airways. I really feel this os something thay coult truely benefit tylers health any help to buy one would be so greatly appreciated. Every penny counts x
