3. Definition
Cough is physiological protective
mechanism which is characterized by
explosive expectoration following a deep
inspiration. Its function is to clear the
tracheobronchial tree of excessive
secretions and foreign body.
4. Cough is often a clue to presence of Respiratory
disease.
Cough provide an essential protective function for human
airways and lungs.
Withought an effective cough reflex we are at risk for -
•retained airway secretion
•Aspirated material
•Predisposing infection
•Respiratory compromise
At the other extreme, excessive coughing
•can be exhausting
•Can be complicated with – emesis, syncope,
muscular pain, rib fracture
•And can aggravate hernia and urinary incontinence.
COUGH
5. Weak or ineffective cough compromises the ability to
clear lower respiratory tract infection, predisposing to more serious
infections and their sequelae.
Causes of impaired cough
•Decrease respiratory muscle strength.
•Chest wall deformity
•Impaired glottic closure or tracheostomy
•Abnormal airway secretions
•Central respiratory depression (anesthesia, sedation or
coma)
Impaired cough
6. Cough mechanism
Spontaneous cough is triggered by stimulation of sensory nerve
endings that are thought to be Primarily Rapidly adopting
receptor and C-fibers.
both chemical (Capsaician) and mechanical stimuli may initiate
the cough.
Afferent nerve ending richly innervate the Pharynx, Larynx, Air
way to the level of terminal bronchioles and also found in
External auditory meatus & Esophagus.
Sensory signal travel via the Vagus and Superior laryngeal
nerve.
7. transient upper airway occlusion
generating positive intra thoracic
pressure as high as 300mmhg.
rapid expiratory flow are generated.
maximizes the velocity of exhalation
Cough reflex involve a highly orchestrated series of involuntary muscular actions.
Bronchial smooth muscle contraction
together with dynamic compression of
airway narrows airway lumen
Vocal cord adduct
Expiratory muscle contract
With sudden release of laryngeal
contraction

Cough History
9. Cough of less than 8 wk duration may be
the early manifestation of a disease causing
chronic cough.
Acute cough occurring in context of more
serious disease such as pneumonia, aspiration,
CHF, pulmonary embolism is usually easy to
diagnose due to the presence of other clinical
features.
10. Assessment of chronic cough
•Regardless of cause cough often worsen when one first lies down at night
or with talking or in association with hyperpnea of exercise; it frequently
improve with sleep.
Exception- pertusis, asthma
•Physical examination seeks clue to the presence of cardiopulmonary
disease, including finding such as wheezing or crackles on chest
examination.
•Examination of auditory canal and tympanic membranes, nasal passage
ways and nails.
•Cough may be manifestation of systemic disease such as Sarcoidosis or
Vasculitis.
•In virtually all instances, evaluation of chronic cough merits a chest
radiograph.
11. Chronic cough with a normal chest
radiograph
When initial assessment with chest examination
and radiograph is normal.
Cough variant asthma
Gastro-esophageal reflux
Post-nasal drainage
Medication (ACE inhibitor)
12. The characteristic of cough originating at
various level of RT
ORIGIN COMMON CAUSE CLINICAL FEATURE
Pharynx Post-nasal-drip History of chronic rhinitis
Larynx Laryngitis, tumor Voice or swallowing altered, harsh or painful
voice
Whooping cough, croup Paroxysm of cough, often associated with strider
Trachea Tracheitis Raw restrosternal pain with cough
Bronchi Bronchitis(acute), COPD Dry or productive, worse in morning
Asthma Usually dry, worse at night
Bronchial carcinoma Persistent (often with haemoptysis)
Lung
Parenchyma
Tuberculosis Productive, often with haemoptysis
Pneumonia Dry initially, productive later
Boncheiectasis Productive, change in posture induce sputum
production
Pulmonary edema Often at night (may be productive of pink, frothy
sputum)
Interstitial fibrosis Dry, irritant and distressing
