After many months of coughing - CT chest scan shows bronchiectasis

Please explain how to do sputum induction. I am another person that does not cough and does not produce sputum. I do have bronchiectasis, but have not been diagnosed with MAC or NTM. I would like to rule those out some day, so it would help to know how to induce getting a sputum sample. Thanks! Donna

Hello Donna, People who have trouble producing sputum should not try to force it on their own. Rather they should be referred to a respiratory therapist for assistance. In addition to nebulizing saline, there are breathing and coughing techniques, positional drainage, percussion and devices that can be used to help.

Forceful, unproductive coughing can cause pain and irritation to lungs, throat, even ribs.

My current pulmonologist actually has an RT on her staff. My previous doc had an experienced RN to help. My friend in a smaller group practice was sent to the respiratory department of the local hospital.

Hi Donna,

I do sputum induction by nebulizing with 4ml of 7% saline. Occasionally, I have to use 2 ampoules, but generally, one does the trick. By about midway through, I have enough moisture built up that I can huff cough up a good sample. At NJH, if you don't produce sputum, they will increase your saline all the way up to 10%, which can be a bit overwhelming for some.
