Tracheostomy tubes can be vital in assisting people with breathing. Sometimes, the inner cannula of the main outer lumen of a tracheostomy tube can become blocked. When this happens, you'll need to replace it quickly to clean it and keep the tube free of mucus. That is what disposable inner cannulas are for. Once they get too coated with mucus, medical professionals can swap them out for a fresh one. MedOnTheGo.com makes sure that you have the inner cannulas you need at a price you can afford.
