Respiratory care is a healthcare discipline that focuses on assessing, diagnosing, and treating patients with breathing disorders and diseases affecting the lungs, such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and sleep apnea. Respiratory therapists play a key role in managing and providing treatments to improve lung function, including administering medications, oxygen therapy, ventilator support, and pulmonary rehabilitation. Other areas of focus within respiratory care include smoking cessation programs, respiratory education, and promoting overall respiratory health and wellness. This field is essential in helping patients of all ages improve their quality of life and respiratory function.
