Respiratory disorders conditions

Respiratory Disorders/Conditions

  • Disorders and conditions of the respiratory system are associated with either the lungs or air passages.

  • There are a number of diseases that interfere with the primary function of the respiratory system effecting either

  • 1) the uptake and delivery of oxygen to the body cells

  • 2) the removal of Carbon Dioxide

  • Some diseases restrict the flow of air in an out of lungs,

  • Others have an inability to deliver sufficient are to the alveoli = _______ surface area which affects gas exchange


Some causes of disease

Some Causes of Disease

  • Primary cause of lung disease =

  • Other Causes = air pollution, airborn irritants, and asbestos.

  • Whatever condition, all results the same

  • Insufficient oxygen is available to the tissues of the body last minute


Asthma

Asthma

  • Chronic respiratory disease characterized by inflammation and swelling of the bronchi and bronchioles that obstructs airflow.

  • Symptoms: coughing, wheezing, tightness of chest, closeness of breathe.

  • Cause: not fully known, but something triggers an inflammation of the lungs which cause it to secrete a lot of sticky mucus in airways which contribute to the reduced airflow.

  • Treatment: bronchodilators (inhalers) or drugs that help dilate the bronchioles making It easier to breathe.


Pneumonia

Pneumonia

  • Disease of the lungs causing the alveoli to inflame (swell) and fill with liquids.

  • Interferes with normal ability to take in oxygen causing the body’s cells to starve for oxygen.

  • Pus an mucus accumulate in alveoli

  • 2 types:

  • Lobar Pneumonia – affects a love of a lung

  • Bronchial Pneumonia – affects patches throughout both lungs

  • Symptoms: fever, cough, shortness of breath

  • Causes: infections by bacteria, viruses, mycoplasmas, fungi

  • Treatment: antibiotics, but still 5% fatality rate


Tuberculosis tb

Tuberculosis (TB)

  • Bacterial infection caused by Myobacterium tuberculosis. Spread when people sneeze or cough

  • Symptoms: coughing, chest pain, weight loss, coughing up blood

  • Cause: not fully known, but something triggers an inflammation of the lungs which cause it to secrete a lot of sticky mucus in airways which contribute to the reduced airflow.

  • Treatment: bronchodilators (inhalers) or drugs that help dilate the bronchioles making It easier to breathe.


Effects of smoking

Effects of Smoking

  • Known to cause lung cancer, emphysema, asthma.

  • 3 substances in smoking that causes problems for the respiratory system

  • Nicotine – natural insecticide. It kills pests and is addictive

  • Carbon monoxide – affect ability to let respiratory system to deliver oxygen to other bodies. Hemoglobin has a much higher tendency to bind to carbon monoxide than oxygen.

  • Tar – black, sticky substance that accumulates preventing exchanges of gas. Tar also causes the cilia lining to stop working.
