A Respiratory Therapist is a healthcare professional who specializes in treating patients with breathing difficulties. They work with individuals suffering from conditions like asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. Their primary responsibilities include administering oxygen therapy, managing ventilators, and conducting diagnostic tests to assess lung function. These therapists often collaborate with doctors and nurses to develop treatment plans tailored to each patient's needs. They also educate patients and their families about respiratory health and proper use of inhalers or other breathing devices. Overall, respiratory therapists play a crucial role in improving patients' quality of life through effective respiratory care.
