A productive cough is a wet or chesty cough in which phlegm or sputum is coughed up. The secretions that you cough up might be thin, frothy, thick or sticky and may be difficult to clear. The colour will vary from clear/white to yellow/green. It is important that you discuss any cough symptoms with your doctor or nurse.
Alongside drinking plenty and making sure you're sitting or lying comfortably, you might also try the following breathing techniques. There are two specific techniques that can help a productive cough.
Repeat the cycle until you feel an improvement.
This technique squeezes and stretches your airways so that secretions can be brought up from deep in your lungs with as little effort as possible. Sit or lie comfortably in your preferred position. Have a glass of water nearby.
Continue the cycle. Take your time – do not rush. As you feel the secretions move up, allow yourself slightly deeper breaths before you huff. When the secretions are high enough you will be able to huff or cough them out.
Try not to cough too early or during the breathing exercise. If you do, take a sip of water, relax and start again.
Try to practice these exercises at least twice a day, eg. first thing in the morning and last thing at night. If you are using a nebuliser, these techniques can be used at the same time.
