My mum is in late stages of this horrid illness. She has been on atropine drops which were working so well but now does not seem to be as effective. The build up of thick salvia is causing mum to cough for 15-20 minutes at a time. We're looking for a suction machine, but confused as to which one is the best. Any recommendations or advice would be great. We need to sort this asap as it is horrible to see her coughing this way, all we can do is watch.
