Oxygenation - answer-✔The process of delivering oxygen to the blood by
diffusion from the alveoli following inhalation into the lungs.

cerebral arteries, increased intracranial pressure and decreased Level of
consciousness (LOC)
-headache
-irritable
How does acid base balance affect the RR - answer-✔increase RR excretes more
CO2
decreased RR retains more CO2

decreased blood carrying O2 cells and blood will shunt to vital organs and leave
peripheries
-peripheral cyanosis
-slow cap refill
-cold extremities
-pallor
-lethargic
-orthostatic hypotension
how does CO2 and O2 affect cognition? - answer-✔increased CO2=decreased O2=
decreased LOC
, if we don't get enough O2 the body can experience discomfort how? - answer-
✔chest or kidney pain
-give pain meds if necessary
how can decrease of perfusion affect the body? - answer-✔-decrease O2 level
