Hi Kelaine, my husband was admitted after his first attempt at chemo. He couldn't swallow water. He was spitting saliva into a cup constantly. In the hospital, they had a suction device (I think it's called a Yankauer) that he could put in his mouth and it helped immediately and tremendously when he couldn't swallow. The DME company set it up at home when they set up his feeding tube pump. Is your husband coughing up or vomiting the mucous? Or is it that it kind of pools in his mouth? If it's a matter of intense drooling/spitting, this device might help. Best wishes to you both,
Lynn
