Chest physiotherapy also is used on patients suffering from lung diseases that cause mucus to collect in the lungs, such as cystic fibrosis. Therapists place patients in positions to help drain mucus, thump and vibrate patients' rib cages, and instruct them to cough. Therapists are increasingly working under the supervision of nurses and are being asked to perform tasks that fall outside of their traditional role. They are expanding into cardiopulmonary procedures like electrocardiograms and stress testing, but also perform other tasks like drawing blood samples from patients. They also keep records of the materials used and charges to patients.
Some therapists teach or supervise other respiratory therapy personnel.
Working Conditions Respiratory therapists generally work between 35 and 40 hours a week. Because hospitals operate around the clock, therapists may work evenings, nights, or weekends. They spend long periods standing and walking between patients' rooms. In an emergency, they work under a great deal of stress. Gases used by respiratory therapists are potentially hazardous because they are used and stored under pressure.
