What is respiration?
Respiration is the act of breathing:
 inhaling (inspiration) - taking in oxygen
 exhaling (expiration) - giving off carbon dioxide

Pharmacological treatment for
Asthma
20
Drugs used in asthma
A. Bronchodilators
 β2 Adrenergic Receptor Agonist: Salbutamol,
Terbutaline, Bambuterol, Salmeterol , Formoterol,
Ephedrine.
 Methylxanthine:Theophylline, Aminophylline, Chonine
theophyllinate, Hydroxyethyl theophylline, Theophylline
ethanolate of piperazine, Doxophylline.
 Anticholinergics: Ipratropium bromide, Tiotropium
bromide.

substance
of anaphylaxis
(SRSA).
34

  • 2. Contents Anatomy and Physiology Of Human Respiratory System Respiratory Diseases Asthma Chronic Obstructive Pulmonary Disease 2
  • 3. Anatomy and Physiology Of Human Respiratory system What is respiration? Respiration is the act of breathing:  inhaling (inspiration) - taking in oxygen  exhaling (expiration) - giving off carbon dioxide 3
  • 4. Respiratory System (cont…) 4 Functional anatomy of the respiratory system: Conducting Zone -nose -nasal cavity -pharynx -larynx -trachea -bronchi Respiratory Zone -respiratory bronchioles -alveolar ducts
  • 6. Respiratory System (Cont…) Basic functions :- Gas exchange Protection 6
  • 7. RESPIRATORY DISEASES COPDASTHMA PNEUMONIA RESPIRATORY TUMORS PULMONARY HAEMORRHAGE PULMONARY EDEMA PULMONARY EMBOLISM PNEUMOTHORAX CYSTIC FIBROSIS TUBERCULOSIS 7
  • 9. What is Asthma..??? Chronic inflammatory disease of the airways. Characterized by reversible airflow obstruction and bronchospasm. 9
  • 10. Symptoms of Asthma  The clinical hallmarks of Asthma  Coughing,  Shortness of breath,  Chest tightness,  Wheezing  The Symptom of Asthma  Smooth muscle contraction  Vascular congestion  Bronchial wall edema  Thick, tenacious secretion 10
  • 11. Causes of Asthma Environmental And Genetic Factors 11
  • 12. 12
  • 14. Diagnosis of Asthma Based on Response to therapy Pattern of symptoms  Response to therapy 14
  • 15. Diagnosis of Asthma (cont..)  Pattern of symptoms List of indicators:  Wheezing  history of any of the following:  Cough, worse particularly at night  Recurrent wheeze  Recurrent difficulty in breathing  Recurrent chest tightness  Symptoms occur or worsen in the presence of:  Exercise  Viral infection  Animals with fur or hair 15
  • 16. Diagnosis of Asthma (cont..) House-dust mites Mold Smoke (tobacco, wood) Pollen Changes in weather Strong emotional expression (laughing or crying hard) Airborne chemicals or dusts Menstrual cycles  Symptoms occur or worsen at night, awakening the patient 16
