Thanks for your response. Not being familiar with the potable suction machine I assume you connect the aspiration suction tips to the machine and then direct the tip to the mucus location. Can you determine if the mucus is below the vocal chords? I was advised not to attempt to suction the mucus if below the vocal chords.
My partners mucus is very thick surrounded by a thinner coating of saliva. This mucus does affect his ability to speak and affects his breathing. He is willing to try the portible suction if no other options arise.
