obstruction of the airway
How are airway obstructions reversed?
positioning and suctioning
decreased amount of oxygen in the blood stream
may lead to hypoxia

too much carbon dioxide in the bloodg
What are the symptoms of hypoxia
retractions (muscles move in during inspiration)
Patients suffering from hypoxia are susceptible to....
respiratory infections due to insufficient inflation of the lungs
secretions pool providing a growth medium for microorganisms
What does the pulse oximeter measure?
changes in arterial oxygen saturation
intravenous dye and jaundice reduce accuracy
