HISTORY TAKING AND GENERAL EXAMINATION OF RESPIRATORY SYSTEM

Seminar Presented by: Dr Himanshu Rana (JR-3)

Page 2: History taking and general examination of respiratory system

Scheme of history taking• Initial enquiry• Chief complaint• History of present illness• Past medical history• Systemic enquiry• Family history• Occupational history• Drug history• Social history• Personal history

Page 3: History taking and general examination of respiratory system

• Symptoms• Cough• Sputum production• breathlessness• Chest Pain• Hemoptysis• Wheeze / Stridor

Page 4: History taking and general examination of respiratory system

Cough• Reflex act of forceful expiration against a

closed glottis generating positive intrathoracic pressure as high as 300 mm Hg.

• Aim is to clear the airways.

Page 5: History taking and general examination of respiratory system
Page 6: History taking and general examination of respiratory system

Acute cough (<3 wks)• Upper respiratory tract infections• Pneumonia• Pulmonary embolism • Congestive Cardiac Failure

Page 7: History taking and general examination of respiratory system

Subacute cough (3- 8 weeks)• Viral infections• Post infective • Post nasal drip• GERD

Page 8: History taking and general examination of respiratory system

Chronic cough >8 wks• Pulmonary Tuberculosis• Bronchial Asthma• COPD• Bronchogenic carcinoma• Eosinophilic bronchitis• Post nasal drip• GERD• Drugs like ACE inhibitors• Congestive cardiac failure

Page 9: History taking and general examination of respiratory system

Nocturnal cough• Post nasal drip.• GERD• Chronic brochitis.• Bronchial asthma.• Obstructive sleep apnea• Left Ventricular Failure• Aspiration

Page 10: History taking and general examination of respiratory system

Sputum• Consistency• Amount• Color• Postural variation• Smell

Page 11: History taking and general examination of respiratory system

Consistency• Serous - Upper Respiratory tract Infection,

Bronchoalvelolar carcinoma • Mucoid - Chronic bronchitis, Bronchial Asthma • Mucopurulent - Bacterial infection

Page 12: History taking and general examination of respiratory system

Amount

Copious Amount– Bronchiectasis– Lung Abscess– Necrotizing pneumonia– Alveolar cell carcinoma– Empyema rupturing into bronchus

(Bronchorrhoea - >100ml sptum/day)

Page 13: History taking and general examination of respiratory system

Color of sputum– Yellow / Green — Bacterial infection– Black — coal worker pneumoconiosis– Pink frothy sputum — Pulmonary edema– Rusty sputum- pneumococcal pneumonia– Red currant jelly sputum- klebsiella – Blood tinged / streaking of sputum- tuberculosis– Anchovy sauce — Ruptured amoebic liver abscess.

Page 14: History taking and general examination of respiratory system

Postural variation– Lung Abscess– Bronchiectasis

Page 15: History taking and general examination of respiratory system

Foul Smell– Lung abscess– Bronchiectasis – Anaerobic bacterial infection

Page 16: History taking and general examination of respiratory system

Dyspnea“Subjective experience of breathing discomfort

that consists of qualitatively distinct sensations that vary in intensity. The experience derives from interactions among multiple physiological, psychological, social, and environmental factors that may induce secondary physiological and behavioural responses.”

(The American Thoracic Society)

Page 17: History taking and general examination of respiratory system

• Onset • Duration• Severity • Aggravating and relieving factors• Postural variation• Diurnal variation

Page 18: History taking and general examination of respiratory system

Onset

Within minutes– Pneumothorax – Pulmonary embolism– Inhalation of foreign body– Larygeal edema– Left heart failure

Page 19: History taking and general examination of respiratory system

Hours to Days– Acute Respiratory Distress Syndrome– Bronchial Asthma– Pneumonia– Left heart failure

Page 20: History taking and general examination of respiratory system

Weeks to Months– COPD– ILD– Pleural effusion– Anemia– Thyrotoxicosis – Left ventricular failure

Page 21: History taking and general examination of respiratory system

Grading of Dysponea (MMRC scale)Grade Description of Breathlessness

0 I only get breathless with strenuous exercise.

1 I get short of breath when hurrying on level ground or walking up a slight hill.

2 On level ground, I walk slower than people of the same age because of breathlessness, or have to stop for breath when walking at my own pace.

3 I stop for breath after walking about 100 yards or after a few minutes on level ground.

4 I am too breathless to leave the house or I am breathless when dressing.

Page 22: History taking and general examination of respiratory system

• Aggravating factors– Exposure to allergen– Exercise– Drugs– Cold whether

• Relieving factors– Medication– Rest– Removal of allergen

Page 23: History taking and general examination of respiratory system

Diurnal and postural variation– Bronchial asthma– Lung abscess– Bronchiectasis

Page 24: History taking and general examination of respiratory system

Haemoptysis

Types• Frank- expectoration of blood only• Spurious- secondary to upper respiratory tract

infection above the level of larynx• Pseudo hemoptysis- due to pigment produced

by gram negative bacteria, Serratia marcescens

Page 25: History taking and general examination of respiratory system

Severity • Mild <100ml /day• Moderate 100-150ml/day• Severe upto 200 ml/day• Massive > 600ml /day or 100ml/day for more

than 3 days or 150 ml/hr.

HAEMOPTYSIS HAEMATEMESIS

Cough precedes Nausea & vomiting precedes

Frothy, may be mixed with sputum No air, mixed with food particles

pH alkaline pH acidic

Bright red Dark brown

H/o respiratory disease h/o peptic ulcer or chronic liver disease

No h/o malena h/o malena present

Investigation: bronchoscopy Investigation: endoscopy

Page 27: History taking and general examination of respiratory system

Causes of hemoptysis

Infection-– TB– Lung Abscess– Bronchiectasis – Pneumonia– Fungal infection (aspergillosis blastomycosis)

Page 28: History taking and general examination of respiratory system

Neoplasm-– Bronchogenic ca– Bronchial adenoma– Metastatic tumour

Page 29: History taking and general examination of respiratory system

CVS– MS– PHT– Pulmonary embolism– AV malfromation

Page 30: History taking and general examination of respiratory system
