Introduction
The common respiratory system disorders :
1. Infections such as pneumonia.
2. Obstructive disorders that obstruct airflow into and out of the
lungs such as asthma, bronchitis and emphysema.
3. Restrictive disorders are conditions that limit normal expansion
of the lungs such as pneumothorax, atelectasis and respiratory
distress syndrome
4. Cancers.

Important terminology
1. Hypoxia : Decreased levels of oxygen in the tissues
2. Hypoxemia : Decreased levels of oxygen in arterial
blood.
3. Hypercapnia : Increased levels of CO2 in the blood
4. Hypocapnia : Decreased levels of CO2 in the blood
5. Dyspnea : Difficulty breathing

Important terminology
6. Tachypnea : Rapid rate of breathing.
7. Cyanosis : Bluish discoloration of skin and mucous
membranes due to poor oxygenation of the blood.
8. Hemoptysis : Blood in the sputum.

ASTHMA
• Respiratory disease characterized by recurrent episodes of dyspnea, cough and wheeze caused by reversible airways obstruction.
![Page 31: Presentation 2: AIRWAY Dr. Bushra Bilal Dr. Miada Mahmoud Rady CLS 243.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697c0071a28abf838cc60be/html5/thumbnails/31.jpg)

Common Asthma causes:
• Animals (pet hair or dander) • Dust • Changes in weather (most often cold weather) • Chemicals in the air or in food • Exercise • Mold • Pollen • Respiratory infections, such as the common cold • Strong emotions (stress) • Tobacco smoke
![Page 33: Presentation 2: AIRWAY Dr. Bushra Bilal Dr. Miada Mahmoud Rady CLS 243.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697c0071a28abf838cc60be/html5/thumbnails/33.jpg)
Management:
• Controlled oxygen therapy• Nabulized bronchodilators e.g. albuterol
(ventolin)• Antibiotics if evidence of infection
(amoxicillin)
