The role of the respiratory therapist is to obtain measurements of respiratory function and instruct the ALS patient and family in the use of therapeutic measures and equipment prescribed by the pulmonary specialist.
Pulmonary function is monitored at each clinic visit.
This can easily be accomplished by exhaling into a spirometer. Also the sensitivity of this test frequently leads to false-positive findings. We find the FVC is easier to perform and is a meaningful indicator of changing respiratory status in the ALS patient. Evidence of respiratory involvement might include shortness of breath with or without exertion, increased lethargy, poor cough, difficulty lying flat, and headaches. The respiratory therapist assists in the instruction of therapeutic measures ordered by the pulmonary specialist such as incentive spirometry, assistive coughing and breathing exercises, suction, intermittent positive pressure breathing, and postural drainage.
