Answer 1

Answer #1

ANSWER:

ARDS is a type of respiratory failure.

occuer rapid and widespread inflamation in lungs

mechanism ;

diffuse injury to the lining cells of microscopic air sac of lungs
surfuctant dysfunction
immune system activation
impaires the blood clotting ability
atelectasis
diffuse alveolar damage and hyaline membrane formation

Net effect is , it impaires the lungs physiological function of gas exchange( oxygen and carbon di oxide)

causes ;

severe pneumonia
sepsis
multiple transfusion of blood
severe burns
drowning
pancreatitis
inhalation injuries

symptoms ;

breathing difficulty
fast breathing
symptoms of precipitating illness

diagnosis ;

chest x ray (bilateral lung opaciyty
decreased Pa02 / Fi02 ratio
ultrasound thorax (anterior subpleural consolidation, spared areas of normal parenchyma. irregular thickened fragmented pleural lines,non homogeneous distribution of B lines)

treatnment ;

icu admission
mechanical ventilation
prone position
fluid managment
medication (corticosteroids, inhaled nitric oxide )
extracorporel membrane oxygenation(ECMO).
