Respiratory Therapy
Respiratory complications are the
leading cause of morbidity and mortality in patients with CF. Thick mucus
blocks the airways in the lungs leading to inflammation and
recurrent infections. With each infection, more damage or scarring occurs
causing lung function to progressively worsen. This is why regular, routine
treatment is so very important to keep secretions cleared and prevent infection . Routine treatment is usually performed 2 times a daily for
maintenance. An increase in cough is usually the first sign of infection and
worsening inflammation. Automatically increase CPT therapy to 3-4 times
daily and contact your CF center for further instructions. With good,
routine treatment, the decline of pulmonary function can be slowed and the
lungs kept healthy for long periods of time. Various airway clearance
techniques and aerosol therapy will be prescribed to assist in clearing
retained secretions from the lungs.

Airway Clearance Therapies
CPT
(chest physical therapy) works in combination with postural drainage by
turning a patient in various positions allowing segments of the lungs
to point downward, then clapping firmly over chest and back on part of the
lung segment to shake the mucus loose. Once loosened, the mucus will fall to
the large airways, then can be coughed out. Postural drainage means placing
patients in a various positions using gravity to help move mucus upwards
toward the large airways. CPT is not painful, but can be time consuming
since you spend 3-5 minutes of clapping over 10-12 lung segments. It is also
difficult for patients to perform on themselves and usually requires another
caregiver. Both patient and caregiver should be comfortable during a
treatment session. The patient should remove tight clothing or jewelry and
wear light, soft clothing such as a T-shirt. CPT should be performed prior
to or at least 30 minutes to 1 hour after eating. A respiratory therapist
will instruct you on proper technique. CPT can be made more enjoyable by
making the most of your time with the child by singing songs, telling
stories, watching favorite video or TV show. Set up a reward system for good
behavior. Train other family members to perform treatments and allowing an
occasional break from the daily routine.
The Vest
System
is a mechanical device that works by high frequency chest oscillation. The
patient wears a jacket which hooks to an air-pulse generator. The air-pulse
generator rapidly inflates and deflates the The Vest
System, gently compressing and
releasing the chest wall up to 20 times per second. This action creates
mini-coughs that dislodge mucus from the bronchial walls and move it along
toward central airways. Once the mucus has moved to the larger airways, it
can be easily removed by coughing. The advantage of the The Vest
System is this therapy
doesn’t require drainage positioning, older patients can administer
independently, and it’s not as labor intensive. For more information talk
with your physician or see www.thevest.com.
Flutter/Acapella are hand held devices that use positive pressure
and vibration to dislodge mucus. Patient exhales through device and causes
vibrations which are transmitted down to the lungs where mucus is shaken
loose from airways. Huffing/cough maneuvers are used to move mucus toward
large airways for removal. The Flutter uses a stainless steel ball mechanism
and the Acapella uses valved magnets to generate vibrations. The advantages
are the small size and ease of carrying while traveling. These devices only
work as well as a patient’s technique, so they are not generally used as the
primary airway clearance therapy. A respiratory therapist will show you how
to use either device correctly.
PEP
therapy is a technique using positive expiratory pressure. The
patient exhales through a valve or restricted opening. This generates a
pressure build up that is transmitted into airways and props them open
during exhalation allowing air to get behind mucus and move it forward.
These are also small hand held devices that can be used as a substitute for
other airway clearance during travel or vacations.
IPV
(intrapulmonary percussive ventilation) works using percussive bursts of air
to maintain a pressure wedge while high velocity flows open airways and
enhance secretion mobilization. These prolonged percussive intervals will
expand the lungs by
hyperinflation, mobilize secretions, and deliver aerosolized medications to
the peripheral airways. Not all medication can be used in an IPV device. A
respiratory therapist will instruct you on proper use. There are IPV
machines available for home use, but these expensive devices are not covered
by most insurance plans.

Aerosol Therapy
Aerosol therapy will be another
part of the daily regimen. The purpose of aerosol therapy is to deliver a
fine mist of medication into the lungs. Necessary equipment includes a
compressor, which blows air into a nebulizer or “cup” changing liquid
medicine into a mist. Aerosol treatments are given to infants with a mask
and are given with mouthpiece to older children (6 years and up). A
respiratory therapist will help demonstrate how to administer different
aerosol medications and provide the proper equipment. There are several
different aerosol medications prescribed for CF. The most common is
Albuterol, a bronchodilator that helps open the
airways and relax the airway muscles. Albuterol is given prior to or during
CPT to aid in secretion clearance. Other types of inhaled medication include
TOBI® (tobramycin
solution for inhalation), an aerosolized antibiotic used to treat lung
infections; Pulmozyme®,
a mucus-thinning drug shown to reduce the number of lung infections and
improve lung function; corticosteroids (Pulmicort Respules, Flovent, Advair),
inhaled to reduce inflammation and swelling in tissues of airways.

Exercise
Exercise is also helpful in
loosening mucus and keeping lungs clear. It is known hard, vigorous exercise
or even laughing and crying often results in coughing bringing up mucus in
people who don’t normally bring up anything during routine airway clearance.
But there is not any scientific data that suggests exercise is equal to or
can replace routine airway clearance therapies and be as effective. So,
patients should be encouraged to be involved in physical activity and do
their daily treatments.

Missed Treatments
Even if daily airway clearance
therapy doesn’t result in immediate coughing or clearing of mucus, mucus is
still shaken loose from the small airways and starts the journey forward to
the large airways. A cough may not generate until mucus is actually in the
large airway. There is good evidence that regular airway clearance is
helpful even if results aren’t seen after a single treatment. In one study,
daily airway clearance was stopped for 3 weeks. The patients did not feel
any different, but had a significant decline in their lung function. Once
treatments resumed, the lung function returned to the previous level. It is
easy for patients to fall into the habit of missing treatments because they
are time consuming and patients do not feel differently if one is skipped.
But over time, missed therapy will result in damage to the lungs and it is
often realized too late to regain lung function.

Smoking
Effects on the Lungs - Everyone knows
cigarette smoke is not good for you and more people are realizing it is also
harmful to the person around the smoker, the innocent bystanders who breathe
the second-hand smoke. Environmental tobacco smoke (ETS) includes both side
stream smoke from the burning end of a cigarette and second-hand smoke
exhaled by smokers in each breath. Both contain noxious gases and other
irritants that hang in the air and can be highly irritating to the lungs of
nonsmokers. Data shows children who are exposed to second-hand smoke have
more colds, pneumonia, bronchitis, ear infections, and respiratory
infections. This is also true for patients with CF who already have abnormal
lung function and have shown worsened lung function when exposed to
second-hand smoke. Children with CF exposed to ETS are more than 4 times
more likely to be hospitalized than patients with CF not exposed.
Effects on Growth – Nicotine is a strong regulator of body weight.
Tobacco smokers generally weigh less than nonsmokers and gain an average of
11 pounds following smoking cessation. It is well known the most important
preventable cause of low birth weight babies is smoking during pregnancy.
Other studies suggest the number of cigarettes smoked in the home daily
during childhood is related to a child’s height. In fact, the amount of
exposure to ETS is a directly linked to the height and weight in children
with CF
How to
Quit - So, bottom line is parents who smoke should not, or at least
not smoke in the house or any other enclosed area like a car. It doesn’t
really help to restrict smoking to certain rooms or only when the child not
around. Parents who have thought about quitting, but haven’t been able too,
often can for the health of their children. Some tips on quitting include:
-
All smokers in the home should
try to quit at the same time. This reduces the temptation to start again
because the cigarettes aren’t around.
-
The day you choose to stop,
remove ALL cigarettes from the house, car, and office. Do not leave them
around for “just in case”.
-
Go cold turkey, stop
completely. It is easier to cut back or reduce the number of cigarettes
per day, but almost always the number will drift back up.
-
Nicotine gum and patches have
been successful in helping people quit smoking, especially in the first
days and at critical times like coffee breaks or while watching TV.
-
Join a smoking cessation
program. The urge to smoke is triggered by social cues or habits. The time
after dinner or the morning cup of coffee may be cues for a cigarette.
Part of learning to stop smoking is to develop a different set of
behaviors when you encounter such a situation. Your local chapter of The
American Lung Association, American Heart Association, or American Cancer
Society is likely to have a smoking cessation program.
