Cyanosis
What is hypoventilation?
Decreased and shallow breathing that might also lead to hypoxia
What is cyanosis?
Blue appearance of skin at late stages of hypoxia
Describe what happens in the lungs during inhalation?
Diaphragm contracts, moving down. Volume expands, pressure gets more negative so air goes in.
Intercostals go up and out to help with expansion
Explain what happens in the chest cavity during exhalation?
Diaphragm relaxes, going up, volume decreases, creating pressure that pushed air out. No other muscles used unless exhalation is forced
How does hypoventilation increase the risk for hypoxemia/hypoxia?
Less air reaches the alveoli, so there is less gas exchange and less oxygen in the blood
What will hypoxia do to the brain?
Abnormal brain function/level of consciousness
What will hypoxia do to renal tissue?
Decrease urine output
What will hypoxia do to tissues of the limbs?
Cause muscle weakness and pain

Environment (altitude, air quality)
Lifestyle (obesity, pregnancy, substance abuse)
Medication
Hypocarbia
Low CO2 levels
Hypercarbia
High CO2 levels
What is the effect of high CO2 levels on the nervous system?
Anesthetic effect, can lead to coma and death
What is death caused by high CO2 called?
Carbon dioxide narcosis
What are the effects of low carbon dioxide on the nervous system?
Acts as a stimulant, so twitching and spasming will occur
