Lesions and Respiration Flashcards
What causes Cheyne-Stokes breathing?
in what patients do you see this?
bilateral forebrain lesions
terminally ill
When do you see hyperapnea with alternating apnea?
with bilateral damage to forebrain
what kind of breathing is this?
Cheyne-Stokes breathing
where is this lesion?
what will it cause?
this is a bilateral forebrain lesion
causes hyperapnea alternating with apnea
When do you see central neurogenic hyperventilation?
when there is damage to:
- periaqueductal gray matter
- Reticular formation in Midbrain or upper Pons
what is this type of breathing?
Central neurogenic hyperventilation
where is this lesion?
what will this cause?
this is damage to the periaqueductal gray matter and reticular formation of the midbrain
will lead to central neurogenic hyperventilation
where is this lesion?
what will this cause?
this is damage to periaqueductal gray matter and upper pons
Apneic breathing
How do you describe central neurogenic hyperventilation?
Sustained, rapid, deep hyperapnea.
how do you describe Cheyne-Stokes breathing?
hyperapnea alternating with apnea
what type of breathing is this?
Apneic breathing
where is this damage?
what will you see because of it?
damage of dorsolateral tegmentum of the Pons
you see Apneic breathing
how do you describe apenic breathing?
prolonged inspiration and prolonged expiration
when do you see cluster breathing?
how do you describe cluster breathing?
midpontine damage
3-5 rapid, deep breaths followed by periods of apnea
what type of breathing is this?
cluster breathing
where is this damage?
what type of breathing will you see?
midpontine
cluster breathing
where is this damage?
what type of breathing will you see with it?
Caudal Pons
ataxic breathing
where is this damage?
what type of breathing will you see?
rostral medulla
ataxic breathing
what type of breathing do you see here?
when do you see this?
resp. distress
damage to ventrolateral medulla or caudal medulla
what damage do you see here?
what type of breathing do see here?
damage to descending axons in the caudal medulla
resp. distress
