Why Respiratory Therapy
Help patients breathe when it matters most
Respiratory therapists care for people whose breathing has been affected by illness, injury, premature birth, chronic disease, or a medical emergency. They assess patients, perform diagnostic testing, administer treatments, manage respiratory equipment, and support patients who require mechanical ventilation.
Respiratory therapists work with patients of all ages, from premature infants in neonatal intensive care to adults managing asthma, emphysema, and other cardiopulmonary conditions.
