Disorders of Ventilation and Diffusion
Impaired ventilation
caused by
airway obstruction
cystic fibrosis
thick mucus
genetic defect
chronic bronchitis
chronic cough
mucus hypersecretion
airway narrowing
asthma
inflammation
wheezing
air cannot move freely in and out of the lungs
Treatment
bronchodilation
corticosteroids
mucolytics
lifestyle changes
oxygen therapy
Impaired diffusion pt. 1
Caused by
alveolar filling
acute respiratory distress syndrome (ARDS)
widespread inflammation
leaky capillaries
fluid accumulation
pneumonia
inflammatory fluid in alveloli
infection
Treatment
antibiotics
CPAP
antibiotics
diuretics
excess fluid in alveoli so gas cannot diffuse properly
Impaired Diffusion pt. 2
Caused by
loss of surface area
alveolar destruction
emphysema
barrel chest
trapping of air in lungs
shortness of breath (dyspnea)
loss of lung tissue elasticity
hypoxemia
Treatment
bronchodilators
oxygen therapy
pulmonary rehab
corticosteroids
less area for oxygen exchange to take place due to wall breakdown
