I am sorry to hear about you situation and the very difficult time that you must be having.
Towards the end of someone's life breathing may become loud and noisy if mucous has built up in the airways. This is because the person isn't coughing or clearing their airways as they normally would do. Some people call this type of breathing the death rattle because it can happen in the last days or hours of life.
Marie Curie describes this clearly and also what you might expect towards the end. Have a look here
