Respiratory Therapy is a specialized healthcare field that focuses on the treatment and management of patients with respiratory and cardiopulmonary disorders. Respiratory therapists work with patients of all ages, from premature infants with underdeveloped lungs to elderly patients with chronic obstructive pulmonary disease (COPD). They work in a variety of settings, including hospitals, clinics, long-term care facilities, and home healthcare. Respiratory therapists are responsible for assessing patients' respiratory function, developing treatment plans, and administering therapies to improve lung function. They may use a variety of techniques, including oxygen therapy, mechanical ventilation, chest physiotherapy, and aerosol medication delivery. Respiratory therapists also monitor patients' progress and adjust treatment plans as needed. In addition to patient care, respiratory therapists may also be involved in research, education, and management. They may conduct research to improve treatment outcomes, teach patients and healthcare professionals about respiratory care, and manage respiratory therapy departments.
