What is Chronic Bronchitis?
A condition that results in the production of purulent sputum for at least 3 months in a row over two consecutive years
Bronchial Mucus
- There are two sources of bronchial mucus: the bronchial glands and the epithelial goblet cells which line the bronchial walls
- In chronic bronchitis, there is an enlargement of the mucus-secreting bronchial glands and an increase in the number of epithelial goblet cells.
- There is also a decrease in the number of ciliated epithelial cells which help to mobilize and remove mucus
Disease process
- Airways become chronically inflamed from ongoing irritation which leads to edema and thickening or hyperplasia of the bronchial walls
- There is a decrease in expiratory airflow rates and prolonged expiration due to airways being obstructed from an increase in bronchial mucus
- The person can experience wheezing with a severe productive cough, dyspnea (laboured, distressed breathing) and bouts of respiratory infection. –> This leads to less tolerance for exercise and eventually no physical reserves left for times of stress
- Blockage of the airways leads to insufficient oxygenation in the alveoli which causes cyanosis (bluish tinge to skin) and general peripheral edema results from ventricular failure
- People with chronic bronchitis tend to retain weight
- A person with combined cyanosis, edema and weight retention is called a “blue bloater”
- Over time, severe chronic bronchitis can lead to pulmonary hypertension, right-sided heart failure and death
Chronic Obstructive Pulmonary Disease (COPD)
- A combination of chronic bronchitis and emphysema
- This most commonly occurs in people who smoke
Causes of Chronic Bronchitis
- Smoking-results in airway inflammation that is thought to trigger the specific pathological changes seen in the airway goblet cells and epithelium
- Environmental factors including air pollution and occupational exposure to inhaled particles or fumes
The Respiratory Tract and Lungs
- In the upper respiratory tract, air flows through the nasal cavity and pharynx where it is warmed and humidified
- The air is filtered and particles are removed by mucosa and cilia
- In the lower respiratory tract, air is transported to the alveoli where gas exchange takes place
- Ventilation is the air exchange from atmosphere to alveoli (opposite to respiration which is the blood transport and exchange of gases at the alveolar capillary membrane
- The trachea branches into left and right main bronchi at the level of the 2nd rib anteriorly and T5 posteriorly
- The bronchi supply the left and right lungs through a further division into lobar and segmental bronchi
- The bronchi further divide into bronchioles, then into terminal bronchioles, respiratory bronchioles and finally alveoli
- The trachea and alveoli are supplied with lots of mucus-producing cells and ciliated cells which line the airways
- The left lung is divided into two lobes and is divided obliquely by a fissure between the left upper and lower lobes from the 5th rib anteriorly to T3 posteriorly
- The right lung is divided into three lobes, upper, middle and lower. The fissure between the upper and middle lobes runs obliquely from the 3rd rib anteriorly to T3 posteriorly. The fissure between the middle and lower lobe runs obliquely from the 6th rib anteriorly to the 5th rib at the level of the lateral border of the scapula
Muscles of Respiration
- Resting Inhalation:
Ta. he diaphragm contracts and flattens
The external intercostals contract, lifting the ribs (increases the anterior/posterior and transverse dimensions of the thorax)
b. The thorax volume increases and the pressure in the lungs decreases
c. Air moves into the lungs
d. The scalenes elevate the first two ribs, becoming active
e. The average adult breathes 10-12 times per minute at rest
- Forced Inhalation:
- The diaphragm descends at least 3-4 intercostal spaces
- The accessory muscles of inhalation are recruited
- SCM’s lift the sternum only when the head and neck are upright or hyperextended
- Subclavius elevates the first rib when the clavicle is fixed
- Levator costarum lifts the ribs posteriorly and superiorly
- Serratus posterior superior raise the 2nd-5th ribs
- Latissimus dorsi raise ribs 9-12
- Pectoralis major raises the sternum and 2nd-6th ribs
- Pectoralis minor lifts the 3rd-5th ribs
- With activity, the average adult breathes 50 times per minute
- Relaxed Exhalation:
a. A passive process
b. The diaphragm relaxes upward into a domed shape
c. The external intercostals and scalenes relax, allowing the ribs to drop
d. The thoracic volume decreases
e. The pressure in the lungs increases, pushing air out of the lungs
- Forced Exhalation:
a. The internal intercostals contract, pulling the ribs downward
b. Rectus abdominis, internal and external obliques and quadratus lumborum are also recruited
Symptom Picture
- Increase in mucus production from the bronchial glands and an increase in the number of goblet cells due to chronic irritation
- Airways are narrow due to chronic inflammation, thickening of the bronchial airways and accumulated mucus
- Decreased mobility of the thoracic joints
- Respiratory infections may be present
- Chronic productive cough which worsens in the morning and evening and in the winter months.
- Mucus is purulent
- Over time, cyanosis occurs, the finger ends are clubbed or bulbous, the person tends to retain weight and peripheral edema results
Health History Questions
- When was the onset of the bronchitis?
- Are there any other respiratory conditions?
- What is their occupation and recreational activities?
- Do they smoke? If so, how frequently?
- Do they know what lobes are affected?
6.Do they have dyspnea? Is sleep disrupted because of this?
- Is the cough productive? Is it severe? What time of day is the cough worse?
- What is the colour of the sputum?
a. Clear or whitish is common
b. Yellow or green indicated infection
c. Blood streaked may be present
d. If it severe, postural drainage is CI’d - What is the quantity of the sputum?
- Have they been hospitalized for chronic bronchitis? When and how long?
- Do they have a fever? If so, massage is CI’d
- Are they taking any medication?
- Are they doing any other modalities?
Observations
- The client may lean forward while sitting to stabilize the shoulder girdle to assist with inhalation
- The accessory muscles of respiration are likely hypertrophied
- The client may have dyspnea or tachypnea (rapid, shallow breathing)
- The client may have apical breathing (using the upper chest only)
- A barrel chest may be present (increased anteroposterior thoracic dimensions)
- Hyperkyphosis, hyperlordosis or scoliosis may be present
- In severe cases, the client may breathe through pursed lips
- Cyanosis may be observed at the nail beds or the lips
- Clubbing of the fingers, weight retention and peripheral edema may be present
Palpation
- The muscles of respiration and the accessory muscles are tender and hypertonic (diaphragm, intercostals, scalenes, SCM, pectoralis major and minor and abdominals)
- Trigger points are likely present in the above muscles and they may feel ropey and fibrosed
- In advanced cases, peripheral edema is palpated
Testing
- AF ROM of the thoracic and cervical spine and the shoulder girdle reveals reduced ranges
- PR ROM including static and motion palpation of the thoracic and cervical spine reveal areas of hypermobility
- AR strength testing for muscles of the shoulder girdle and the abdominals may be performed, assessing for possible weakness
Special Tests:
- Vocal fremitus test:
a. To assess for areas of bronchial congestion, due to emphysema or chronic bronchitis
b. Place client in a prone position
c. Place relaxed hands on the client’s thorax and move them over the various aspects of the thorax
d. While doing this, have the clint repeat words containing nasal sounds (“ninety-nine”) which will cause the thorax to vibrate in a palpable manner.
e. The vibrations will be the most noticeable over the lungs and bronchi
f. Repeat in the supine position
g. Positive: if the vibrations are decreased over the lungs and bronchi. Indicative of congestion due to infected mucus, serum or lymph, indicating which pleural lobe is affected
- Mediate percussion test:
a. To assess the lung density, specifically for the presence of mucus congestion in specific lobes as in chronic bronchitis or hyperinflation in emphysema
b. Place client in the prone position, and then in supine
c. Place the middle finger of the non-dominant hand flat on the thorax along an intercostal space
d. With the tips of the 1st and 2nd fingers of the dominant hand, tap firmly on the finger positioned on the thorax
e. Repeat tapping over various aspects of the thorax
f. The sound is duller over areas of congestion and more resonant over hyperinflated lungs. The sound is also duller over solid areas, such as the heart and abdomen
Contraindications
- Do not exhaust client with overtreatment or prolonged painful techniques
- Joint play techniques to the ribs with rib hypermobility and a history of subluxation
- Postural drainage with severe hemoptysis (lots of blood in sputum) severe pulmonary edema, congestive heart failure, pulmonary embolism, severe hypertension or hypotension, recent myocardial infarction
- Do not use postural drainage directly after the client has eaten
- Tapotement over bony prominences
- Prolonged tapotement that accompanies postural drainage with chest wall pain unstable angina, anticoagulation therapy, osteoporosis, rib fracture, prolonged steroid therapy, hemoptysis, untreated lung abscesses, pulmonary embolism and open thoracic wounds or burns
- A client with cardiac or renal disorders should not increase the daily intake of water to thin mucus secretions
General Treatment Considerations
- In the client has long standing severe chronic bronchitis where there is a possibility of hypertension, the therapist should monitor the client’s blood pressure before and after the treatment
- Positioning of the client depends on the structures to be treated, the location of the affected lobes and the client’s general health
- Positioning during the massage is increasingly important with more severe cases of bronchitis. The time that the client spends in the supine position is reduced or the client is placed only in a side lying position avoiding supine entirely
- The prone position has shown to improve ventilation and oxygenation, while supine does the opposite
- With unilateral lung diseases, lying on the unaffected side increases oxygenation than lying supine
- When the disease is bilateral, lying on the right side increases oxygenation
- Hydrotherapy such as a facial steam for 5 mins prior to the massage will help to thin the mucus
