I tested the vest two month after my last bout of pneumonia. I have a strong cough even after all these years. I've had numerous chest tubes and have gone through everything Linda Lisa mentioned with Gary. The vest didn't make my cough more productive so we sent it back.

Linda Lisa, if Gary's high pressure alarm went off 50-100 time a day his high pressure alarm sensitivity needs turned up some. Mine's on 65, I have a LP10. No we didn't get permission from the doctor to change that setting either. Who needs anyone's stinkin permission?!? LoL
