Heart rate and blood pressure swings are commonly noted with mast cell disorder symptoms but what about normal breath rate?  Most sources indicate that the typical healthy adult should have a resting breath rate of 12 to 15 breaths per minute.  Mine is consistently about twice that even without an activation flare up.  I have had my pulmonary function thoroughly checked and there is no indication of any abnormality.  I have never smoked and have no diseases that are not mast cell related.  Is an elevated resting respiratory rate common with us?
