Is it ok to have carpet in my home if a respiratory sensitive person lives in the home?

Yes it is okay to have carpet in homes where a respiratory sensitive person lives.  In fact, some studies have indicated carpet may be better for those sensitive to allergies.  Carpet can actually trap particulates and allergens from the air.  The average fine dust concentration in indoor rooms equipped with smooth flooring material is higher than those in which wall-to-wall carpeting is installed.  If you have carpet in your home, the key is to vacuum and clean regularly.
