Hi,
Your partner seems to have all exposures ( asbestos,
smoking) that is harmful to respiratory function.
There is all the possiblity that he has developed recurrent allergic
cold symptoms due to exposure to asbestos fibers /smoking.All the chances of allergic
bronchitis supplemented by heart problems must have taken him to a great suffering.
How ever specially the type of sputum he has needs a through examination & nesessery investigations to exclude condition like Mesanthelioma- which is a hazard of exposure to asbestos fibers.
He also needs treatment for his allergic bronchitis after consulting a chest specialist & also the investigations suggested by him.
Usually specific antibiotic,broncho dialater ( oral/nasal inhalation), anti allergic pills,
steroids if indicated,with
cough syrups are given to such patients.
To were mask while working with asbestos/to leave the job, to stop smoking are the preventive steps for good health.
Thanks.
