Extra Flashcards
What do sickle cells do to blood flow
they interupt blood flow and cause turbluent blood flow, low blood pressure, lower o2 transport
What organ is responible for removing old damaged blood cells
spleen
What is the difference between sickle cell disease and sickle cell triats
disease: all rbcs
trait: 1/2
Flow equation
F=delta p (pressure difference between two points)/R (resistance to flow
Resistance equation
R=8Ln/pir^4
-L- vessel length
n=viscosity of blood
ectopic pacemaker
abnormal, any site driving ventrivuclar ecitation
tachycardia
HR over 100 beats/min
bradychardia
HR slower than 60 beats/min
CO formula
co=HR x SV
Map equation
DP+1/3(pp)
PP equation
Sp-dp
x/y during cuff
x= when blood can overcome pressure by cuff
y=no longer turbulent flow
CO2 into capillaries
most in bicarbonate
-bicarbonate ions diffuse out to the plasma
-to be exchanged for choloride ions and hydrogen ions bind to hemglobin
-that has released oxygen
co2 caps to alveoli
high o2 favors binding to hemoglobin which releaes hydrogen ions and carbon dioxide
-same carbonic anhydrase and converts ions back to carbon dioxide to be breathed out
