Emphysema
Why oxygen should be used with caution in COPD patients
Compare with normal respiration
Normal: driven by the O2 level of CO2 in arteries, increase CO2 trigger Ventilation
COPD: chronically high in CO2 level in blood, body begin to rely more on O2 receptors, increase O2 decrease rate of respiration
Carefully monitored
