therapists, but a growing number of therapists will work in respiratory therapy
clinics, nursing homes, home health agencies, and firms that supply respiratory
equipment for home use.
· Job opportunities will be best for therapists with cardiopulmonary care skills or experience working with newborns and infants.
Nature of the WorkRespiratory therapists and respiratory therapy
technicians--also known as respiratory care practitioners--evaluate,
treat, and care for patients with breathing disorders. Respiratory therapists
assume primary responsibility for all respiratory care treatments, including
the supervision of respiratory therapy technicians. Respiratory therapy technicians
provide specific, well-defined respiratory care procedures under the direction
of respiratory therapists and physicians.
In clinical practice, many of the daily duties of therapists and technicians
overlap, although therapists generally have more experience than technicians.
In this statement, the term respiratory therapists includes both respiratory
therapists and respiratory therapy technicians.
To evaluate patients, respiratory therapists test the capacity of the lungs and analyze oxygen and carbon dioxide concentration. They also measure the patient's potential of hydrogen (pH), which indicates the acidity or alkalinity level of the blood. To measure lung capacity, patients breathe into an instrument that measures the volume and flow of oxygen during inhalation and exhalation. By comparing the reading with the norm for the patient's age, height, weight, and sex, respiratory therapists can determine whether lung deficiencies exist. To analyze oxygen, carbon dioxide, and pH levels, therapists draw an arterial blood sample, place it in a blood gas analyzer, and relay the results to a physician.
Respiratory therapists treat all types of patients, ranging from premature infants whose lungs are not fully developed, to elderly people whose lungs are diseased. These workers provide temporary relief to patients with chronic asthma or emphysema, as well as emergency care to patients who are victims of a heart attack, stroke, drowning, or shock.
To treat patients, respiratory therapists use oxygen or oxygen mixtures, chest physiotherapy, and aerosol medications. To increase a patient's concentration of oxygen, therapists place an oxygen mask or nasal cannula on a patient and set the oxygen flow at the level prescribed by a physician. Therapists also connect patients who cannot breathe on their own to ventilators that deliver pressurized oxygen into the lungs. They insert a tube into a patient's trachea, or windpipe; connect the tube to the ventilator; and set the rate, volume, and oxygen concentration of the oxygen mixture entering the patient's lungs.
Therapists regularly check on patients and equipment. If the patient appears to be having difficulty, or if the oxygen, carbon dioxide, or pH level of the blood is abnormal, they change the ventilator setting according to the doctor's order or check equipment for mechanical problems. In homecare, therapists teach patients and their families to use ventilators and other life support systems. Additionally, they visit several times a month to inspect and clean equipment and ensure its proper use and make emergency visits, if equipment problems arise.
Respiratory therapists perform chest physiotherapy on patients to remove mucus from their lungs and make it easier for them to breathe. For example, during surgery, anesthesia depresses respiration, so this treatment may be prescribed to help get the patient's lungs back to normal and to prevent congestion. Chest physiotherapy also helps patients suffering from lung diseases, such as cystic fibrosis, that cause mucus to collect in the lungs. In this procedure, therapists place patients in positions to help drain mucus, thump and vibrate patients' rib cages, and instruct them to cough.
Respiratory therapists also administer aerosols—liquid medications suspended in a gas that forms a mist which is inhaled—and teach patients how to inhale the aerosol properly to assure its effectiveness.
In some hospitals, therapists perform tasks that fall outside their traditional role. Tasks are expanding into cardiopulmonary procedures like electrocardiograms and stress testing, as well as other tasks like drawing blood samples from patients. Therapists also keep records of materials used and charges to patients.
Working ConditionsRespiratory 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, therapists work under a great
deal of stress.
Because gases used by respiratory therapists are stored under pressure, they are potentially hazardous. However, adherence to safety precautions and regular maintenance and testing of equipment minimize the risk of injury. As in many other health occupations, respiratory therapists run a risk of catching infectious diseases, but carefully following proper procedures minimizes this risk.
Respiratory therapists held about 118,000 jobs in 2009. More than 4 out of 5 jobs were in hospital departments of respiratory care, anesthesiology, or pulmonary medicine. Most of the remaining jobs were in offices of physicians or other health practitioners, consumer-goods rental firms that supply respiratory equipment for home use, nursing care facilities, and home health care services. Holding a second job is relatively common for respiratory therapists. About 13 percent held another job, compared with 5 percent of workers in all occupations.
Training, Qualifications, Adv.Formal training is necessary for entry to
this field. Training is offered at the postsecondary level by medical schools,
colleges and universities, trade schools, vocational-technical institutes, and
the Armed Forces. Formal training programs vary in length and in the credential
or degree awarded. Some programs award associate's or bachelor's degrees and
prepare graduates for jobs as registered respiratory therapists (RRTs). Other,
shorter programs award certificates and lead to jobs as entry-level certified
respiratory therapists (CRTs). According
to the Committee on Accreditation for Respiratory Care (CoARC), there were 334
accredited RRT programs and 102 accredited CRT programs in the United States
Areas of study for respiratory therapy programs include human anatomy and physiology, chemistry, physics, microbiology, and mathematics. Technical courses deal with procedures, equipment, and clinical tests.
More than 40 States license respiratory care personnel. Aspiring respiratory care practitioners should check on licensure requirements with the board of respiratory care examiners for the State in which they plan to work.
The National Board for Respiratory Care (NBRC) offers voluntary certification and registration to graduates of CoARC-accredited programs. Two credentials are awarded to respiratory therapists who satisfy the requirements: Registered Respiratory Therapist (RRT) and Certified Respiratory Therapist (CRT). Graduates from 2- and 4-year programs in respiratory therapy may take the CRT examination. CRTs who meet education and experience requirements can take two separate examinations, leading to the award of the RRT. Either the CRT or RRT examination is the standard in the States requiring licensure.
Most employers require applicants for entry-level or generalist positions to hold the CRT or be eligible to take the certification examination. Supervisory positions and those in intensive care specialties usually require the RRT (or RRT eligibility).
Therapists should be sensitive to patients' physical and psychological needs. Respiratory care practitioners must pay attention to detail, follow instructions, and work as part of a team. In addition, operating complicated equipment requires mechanical ability and manual dexterity.
High school students interested in a career in respiratory care should take courses in health, biology, mathematics, chemistry, and physics. Respiratory care involves basic mathematical problem solving and an understanding of chemical and physical principles. For example, respiratory care workers must be able to compute medication dosages and calculate gas concentrations.
Respiratory therapists advance in clinical practice by moving from care of general to critical patients who have significant problems in other organ systems, such as the heart or kidneys. Respiratory therapists, especially those with 4-year degrees, may also advance to supervisory or managerial positions in a respiratory therapy department. Respiratory therapists in home care and equipment rental firms may become branch managers. Some respiratory therapists advance by moving into teaching positions.
Job OutlookJob opportunities are expected to remain good. Employment of respiratory therapists is expected to increase faster than the average
Older Americans suffer most from respiratory ailments and cardiopulmonary diseases such as pneumonia, chronic bronchitis, emphysema, and heart disease. As their numbers increase, the need for respiratory therapists will increase, as well. In addition, advances in treating victims of heart attacks, accident victims, and premature infants (many of whom are dependent on a ventilator during part of their treatment) will increase the demand for the services of respiratory care practitioners.
Opportunities are expected to be favorable for respiratory therapists with cardiopulmonary care skills and experience working with infants.
Although hospitals will continue to employ the vast majority of therapists, a growing number of therapists can expect to work outside of hospitals in respiratory therapy clinics, offices of physicians, nursing homes, or homecare.
