Skillful providers of respiratory care are in increasing demand. Respiratory Care Practitioners are prepared to administer pulmonary care under the direction of licensed physicians. Respiratory Therapists assist physicians in the diagnosis and treatment of lung and breathing disorders. These tasks include administering medical gases, breathing tests, medications by inhalation and drawing of blood for analysis. Knowledge of special life-support equipment and methods of monitoring the critically-ill patients are required of respiratory care practitioners. Individuals educated as respiratory therapists must complete a minimum of two years of education. Upon completing the minimum education, graduates are eligible to sit for national board examinations to become a certified respiratory therapist (CRT) and then a registered respiratory therapist (advanced level).
