Actual or hypothetical respiratory control centers in the pons | Apneustic center, Pnemotaxic center |
Respiratory control centers in the medulla | VRG(ventral resp group, DRG(dorsal resp group) |
Respond to overinflation and underinflation of the lungs | Stretch receptors in the lungs |
Respond to decreased oxygen levels in the blood | Chemoreceptors in the aortic arch and the carotid body |
Also called the inspiratory center | dorsal resp group(DRG) |
Medullary area that contains approximately even numbers of neurons involved in inspiration and expiration | ventral resp group(VRG) |
The breathing "rhythm" center | dorsal resp group(DRG) |
Basically acts to inhibit the dorsal respiratory group(DRG) | Pneumotaxic center |
Why is it inadvisable to administer pure O2 to a patient who suffers from pulm dz and retains carbon dioxide? | Declining oxygen level provide the respiratory drive therefore pure oxygen would cause apnea |
Arterial PO2 below 60mmHg stimulates hyperventilation primarily affects: | Peripheral chemoreceptors |
Decrease in arterial pH stimulates hyperventilation primarily affects: | Peripheral chemoreceptors |
Increase in PCO2 in the CSF causes increases in respiratory rate and depth primarily affects: | central chemoreceptors |
