|
|
Term
The nervous system regulates the rate & depth of respiration by the respiratory center.

|
Definition
|
|
Term
| You are caring for a pt. w/ COPD. You review lab results you find his CO2 levels is abnormally high. An elevated CO2 level in this pt. may lead to which condition? |
|
Definition
decreased need for supplemental O2
When the center is stimulated, the rate & depth of breathing are increased. an excessive CO2 is exhaled. A lesser stimulus to the respiatory center is decreased oxygen in arterial blood. |
