Nature of the Work
Respiratory therapists and respiratory therapy
technicians—also known as respiratory care
practitioners—evaluate, treat, and care for patients with
breathing or other cardiopulmonary disorders. Practicing
under the direction of a physician, respiratory therapists
assume primary responsibility for all respiratory care
therapeutic treatments and diagnostic procedures, including
the supervision of respiratory therapy technicians.
Respiratory therapy technicians follow 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; furthermore, the two have the same
education and training requirements. However, therapists
generally have greater responsibility than technicians. For
example, respiratory therapists will consult with physicians
and other health care staff to help develop and modify
individual patient care plans. Respiratory therapists also
are more likely to provide complex therapy requiring
considerable independent judgment, such as caring for
patients on life support in intensive-care units of
hospitals. In this Handbook statement, the term
respiratory therapists includes both respiratory
therapists and respiratory therapy technicians.
Respiratory therapists evaluate and treat all types of
patients, ranging from premature infants whose lungs are not
fully developed to elderly people whose lungs are diseased.
Respiratory therapists 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 evaluate patients, respiratory therapists interview
them, perform limited physical examinations, and conduct
diagnostic tests. For example, respiratory therapists test
patients’ breathing capacity and determine the concentration
of oxygen and other gases in patients’ blood. They also
measure patients’ pH, which indicates the acidity or
alkalinity of the blood. To evaluate a patient’s lung
capacity, respiratory therapists have the patient 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 provide information that
helps determine whether the patient has any lung
deficiencies. 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, who then may make treatment decisions.
To treat patients, respiratory therapists use oxygen or
oxygen mixtures, chest physiotherapy, and aerosol
medications. When a patient has difficulty getting enough
oxygen into his or her blood, therapists increase the
patient’s concentration of oxygen by placing an oxygen mask
or nasal cannula on the 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. The therapists
insert a tube into the 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 perform regular assessments of patients and
equipment. If the patient appears to be having difficulty
breathing or if the oxygen, carbon dioxide, or pH level of
the blood is abnormal, therapists change the ventilator
setting according to the doctor’s orders or check the
equipment for mechanical problems. In home care, therapists
teach patients and their families to use ventilators and
other life-support systems. In addition, therapists visit
patients several times a month to inspect and clean
equipment and to ensure its proper use. Therapists also 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 chest physiotherapy 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.
Therapists place patients in positions that help drain
mucus, and then vibrate the patients’ rib cages and instruct
the patients 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 ensure its effectiveness.
In some hospitals, therapists perform tasks that fall
outside their traditional role. Therapists’ tasks are
expanding into areas such as pulmonary rehabilitation,
smoking cessation counseling, disease prevention, case
management, and polysomnography—the diagnosis of breathing
disorders during sleep, such as apnea. Respiratory
therapists also increasingly treat critical care patients,
either as part of surface and air transport teams or as part
of rapid-response teams in hospitals.
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, therapists work under a great deal
of stress. Respiratory therapists employed in home health
care must travel frequently to the homes of patients.
Respiratory therapists are trained to work with hazardous
gases stored under pressure. 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 the risk of catching an
infectious disease, but carefully following proper
procedures minimizes this risk.
Training, Other Qualifications, and Advancement
Formal training is necessary for entry into this field.
Training is offered at the postsecondary level by colleges
and universities, medical schools, vocational-technical
institutes, and the Armed Forces. An associate’s degree is
required for entry into the field. Most programs award
associate’s or bachelor’s degrees and prepare graduates for
jobs as advanced respiratory therapists. A limited number of
associate’s degree programs lead to jobs as entry-level
respiratory therapists. According to the Commission on
Accreditation of Allied Health Education Programs (CAAHEP),
51 entry-level and 329 advanced respiratory therapy programs
were accredited in the United States, including Puerto Rico,
in 2005.
Among the areas of study in respiratory therapy are human
anatomy and physiology, pathophysiology, chemistry, physics,
microbiology, pharmacology, and mathematics. Other courses
deal with therapeutic and diagnostic procedures and tests,
equipment, patient assessment, cardiopulmonary
resuscitation, the application of clinical practice
guidelines, patient care outside of hospitals, cardiac and
pulmonary rehabilitation, respiratory health promotion and
disease prevention, and medical recordkeeping and
reimbursement.
The National Board for Respiratory Care (NBRC) offers
certification and registration to graduates of programs
accredited by CAAHEP or the Committee on Accreditation for
Respiratory Care (CoARC). Two credentials are awarded to
respiratory therapists who satisfy the requirements:
Registered Respiratory Therapist (RRT) and Certified
Respiratory Therapist (CRT). Graduates from accredited
entry-level or advanced-level programs in respiratory
therapy may take the CRT examination. CRTs who were
graduated from advanced-level programs and who meet
additional experience requirements can take two separate
examinations leading to the award of the RRT credential.
All States (except Alaska and Hawaii), the District of
Columbia, and Puerto Rico require respiratory therapists to
obtain a license. Passing the CRT exam qualifies respiratory
therapists for State licenses. Also, most employers require
respiratory therapists to maintain a cardiopulmonary
resuscitation (CPR) certification. Supervisory positions and
intensive-care specialties usually require the RRT or at
least 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 advanced equipment
requires proficiency with computers.
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
dosages of medication and calculate gas concentrations.
Respiratory therapists advance in clinical practice by
moving from general care to the care of critically ill
patients who have significant problems in other organ
systems, such as the heart or kidneys. Respiratory
therapists, especially those with bachelor’s or master’s
degrees, also may advance to supervisory or managerial
positions in a respiratory therapy department. Respiratory
therapists in home health care and equipment rental firms
may become branch managers. Some respiratory therapists
advance by moving into teaching positions.
Employment
Respiratory therapists held about 118,000 jobs in 2004.
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.
Job
Outlook
Job opportunities are expected to be very good,
especially for respiratory therapists with cardiopulmonary
care skills or experience working with infants. Employment
of respiratory therapists is expected to
increase faster than average for all occupations through
the year 2014, because of substantial growth in the numbers
of the middle-aged and elderly population—a development that
will heighten the incidence of cardiopulmonary disease—and
because of the expanding role of respiratory therapists in
the early detection of pulmonary disorders, case management,
disease prevention, and emergency care.
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 inhalable medications and
in the treatment of lung transplant patients, heart attack
and 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.
Although hospitals will continue to employ the vast
majority of therapists, a growing number can expect to work
outside of hospitals in home health care services, offices
of physicians or other health practitioners, or
consumer-goods rental firms.
Earnings
Median annual earnings of respiratory therapists were
$43,140 in May 2004. The middle 50 percent earned between
$37,650 and $50,860. The lowest 10 percent earned less than
$32,220, and the highest 10 percent earned more than
$57,580. In general medical and surgical hospitals, median
annual earnings of respiratory therapists were $43,140 in
May 2004.
Median annual earnings of respiratory therapy technicians
were $36,740 in May 2004. The middle 50 percent earned
between $30,490 and $43,830. The lowest 10 percent earned
less than $24,640, and the highest 10 percent earned more
than $52,280. Median annual earnings of respiratory therapy
technicians employed in general medical and surgical
hospitals were $36,990 in May 2004.
Under the supervision of a
physician, respiratory therapists administer respiratory
care and life support to patients with heart and lung
difficulties. Other workers who care for, treat, or train
people to improve their physical condition include
registered nurses, occupational therapists, physical
therapists, and radiation therapists.
