respiratory 7; ARDS and respiratory failure Flashcards
surfactant deficiency obstruction in bronchus compression of lung pulmonary edema lung fibrosis can all cause
atelectasis
increase permeability of alveolar/ capillary membrane
edema leads to surfactant inactivation (stiffness)
impaired gas exchange (hypoxia)
increase alveolar collapse
organ failure
60% fatal
acute respiratory distress syndrome
hypoventilation and ventilation can cause
respiratory failure
incomplete expansion of the lung
atelectasis
ventilation
perfusion mismatch
manifestation meaning
sign of ailment
acute respiratory distress syndrome
sudden failure of respiratory system as a result of fluid accumulation in alveoli
DVT
deep vein thrombosis
sudden collapse
crushing chest pain
loss of consciousness
often fatal
massive embolus
hypoxemia
cyanosis
hypercapnia are sx of
respiratory failure
perfusion mismatch
ventilation
ALI
acute lung injury
abnormal rapid breathing
tachypnea
blood clot in pulmonary artery
sometimes starts as DVT
pulmonary embolus
massive embolus sx
sudden collapse
crushing chest pain
loss of consciousness
often fatal
amount of co2 for respiratory failure
more than 50 mmHg PCO2
