what is autoregulation affected by
Give this one a try later!
lactic acid, pyruvic acids and CO2
alpha 1 nonselective beta receptor blockers
Give this one a try later!
block alpha receptors in the vasculature to cause vasodilation and beta
receptors in the heart and lungs to decrease heart rate and contractility
carvedilol and labetalol
,autoregulation is lost when
Give this one a try later!
the systemic MAP is <50 and >150
traumatic brain injury
ICH
ischemic strokes
when ICP is >35 for more than 20-30 mins
What is procalcitonin used for?
Give this one a try later!
used to detect sepsis and severe sepsis causd by a bacterial organism
clinical signs of impending brain herniation
Give this one a try later!
significant pupillary asymmetry
unilateral or bilateral fixed and dilated pupil
decorticate or decerberate posturing
respiratory depression
why is norepi preferred in sepsis
Give this one a try later!
, potent vasoconstrictor without adverse side effects of tachycardia and
other dysrythmias
symptoms of ICH
Give this one a try later!
altered LOC
N/V
sudden, severe headache
seizures
sudden weakness or paralysis
sudden vision changes
loss of balance or coordination
difficulty understanding, speaking
what happens when the first line of defense is penetrated
Give this one a try later!
immune mediated inflammatory reaction
- series of innate (inflammatory) and acquired (immune) responses
these two defenses are the second and third line of defense
- the body identifies harmful molecules and rapidly releases neutrophils to
the tissue injury (second line of defense)
then 48 hours later there is an influx of cells consisting of macrophages
and T cells (third line of defense)
impact of hypoxemia: GI
, Give this one a try later!
absence of bowel sounds may be late indication of blood being shunted to
vital organs
can cause an ileus
strength of contraction is determined by
Give this one a try later!
LVEF; the vigor of contraction regardless of preload
what happens in ARDS
Give this one a try later!
diffuse, inflammatory lung injury leads to increased pulmonary vascular
permeability and as a result, fluid leaks from the capillaries into the alveoli
which interferes with gas exchange
cardiac output

the effectiveness of the pump to circulate blood throughout the body
