Patients in the late stages of amyotrophic lateral sclerosis (ALS) must undergo a tracheotomy because, by this stage, they have completely lost their motor abilities, including the muscle strength needed for breathing. Consequently, they lack the strength to breathe on their own, leaving them unable to survive without a ventilator. They must rely continuously on a ventilator to breathe as they cannot do it themselves. Therefore, if a ventilator is needed over the long term, a tracheotomy is necessary. This is because other methods, such as inserting tubes through the mouth or nose into the trachea to connect to the ventilator, are quite uncomfortable. Comparatively, tracheotomy offers a bit more comfort, making it a necessary procedure for connecting to a ventilator for long-term use and achieving greater comfort.
