1. Understanding Cough:
Causes, Symptoms, and Care
Objective: To understand the definition, history,
anatomy, pathophysiology, signs and symptoms,
treatment, and caregivers' responsibilities for
cough.

2. Introduction
Coughing is a reflex action that helps to clear the
airways of irritants, mucus, or foreign substances. It is a
common symptom associated with various respiratory
conditions and can be acute or chronic.
Coughing can be productive (producing mucus or
phlegm) or non-productive (dry or irritating). In this
response, we will explore the definition, history,
anatomy and physiology, pathophysiology, signs and
symptoms, treatment, and caregiver responsibilities
related to coughing.

3. Definition of Terms
Cough: A reflex action that helps clear the throat or airways of
mucus, irritants, or foreign substances.
Acute cough: Lasting less than 3 weeks.
Chronic cough: Lasting more than 8 weeks.
Productive cough: Coughing up mucus or phlegm.
Non-productive cough: Dry cough without mucus production.

4. History
• Cough has been a recognized symptom throughout history.
• Ancient civilizations used various remedies to alleviate cough.
• Medical advancements have led to a better understanding of cough and its
underlying causes.

5. Anatomy and Physiology
The respiratory system
is responsible for
coughing.
Key organs involved:
lungs, trachea, bronchi,
and diaphragm.
Cough receptors in the
airways are stimulated by
irritants or excessive
mucus.
The cough reflex is
triggered, resulting in
forceful expulsion of air
to clear the airways.

6. Pathophysiology
Cough can be caused by multiple factors:
• Respiratory infections (e.g., cold, flu, pneumonia).
• Allergies and asthma.
• Chronic conditions (e.g., chronic obstructive pulmonary disease - COPD).
• Smoking and environmental pollutants.
• Gastroesophageal reflux disease (GERD).

7. Signs and Symptoms
• Primary symptom of coughing:
• Forceful expulsion of air from the lungs, accompanied by a characteristic sound
• Other associated signs & symptoms:
• Productive cough with phlegm or mucus
• Chest congestion or tightness
• Sore throat or hoarseness
• Fatigue or malaise
• Fever (in case of respiratory infections.)

8. Treatment
• Treatment depends on the underlying cause and severity of the cough.
• Options may include:
• Over-the-counter cough suppressants or expectorants.
• Prescription medications (e.g., bronchodilators, antibiotics).
• Allergy management.
• Smoking cessation.
• Lifestyle changes (e.g., humidification, avoiding triggers).
• Home remedies (e.g., drinking plenty of fluids, using a saline nasal rinse, using a cough
lozenge).

9. Caregivers’ Responsibilities for Cough
• Caregivers play an essential role in managing cough in individuals who are unable to
care for themselves.
• Responsibilities may include:
• Providing appropriate medication administration as prescribed.
• Monitoring and documenting the frequency and severity of cough episodes.
• Assisting with maintaining a clean and healthy environment.
• Encouraging hydration and proper nutrition.
• Promptly seeking medical attention if the cough worsens or becomes concerning.
