Mrs. Castor needed to use a Spirometer in the first book, "Summer" of the Four Season Series.

A spirometer measures the volume of air that is taken in and put out by the lungs.  The indicator encourages the patient to maintain an appropriate rate of intake of air to work towards the lungs being able to work at capacity.  The main reason Mrs. Castor needed it was to exercise her lungs by breathing deeply to make sure she didn't develop pneumonia.
