Haldane effect
incorrect
2.
Fick's first law of Diffusion
incorrect
3.
Formula for Total oxygen content of blood
incorrect
4.
For the arterial oxygen content to be adequate there also must be?
incorrect
5.
What is the most important facto in determining the alveolar partial pressure of oxygen (PAO2)?
incorrect
6.
2 factors that account for the 5-10 mm Hg difference in calculated PaO2 are?
incorrect
7.
What is the alveolar air equation formula?
incorrect
8.
The PaO2 of healthy person breathing at sea level is approximately how much less than the calculated PaO2?
incorrect
9.
Diffusion in the normal lung mainly depends on?
incorrect
10.
In areas with low V/Q the alveolar PO2 is? PCO2 is?
incorrect
11.
What does ventilation perfusion imbalances usually occur in lung disease? Why?
incorrect
12.
A high pH shifts a curve to the?
incorrect
13.
Fetal hemoglobin causes a shift to the?
incorrect
14.
IN theory V/Q imbalance should cause a rise in PACO2. However many patients who are hypoxemic because of a V/Q imbalance have a low or normal PaCO2. What does this suggest?
incorrect
15.
Alkalosis, chronic hypoxemia, and anemia all increase or decrease 2,3-DPG concentrations?
incorrect
16.
What does impaired CO2 removal by the lungs cause?
incorrect
17.
In what three ways will hypoxia occur?
incorrect
18.
To compensate for high PCO2 values with V/Q imbalances what must happen?
incorrect
19.
Formula for Dissolve oxygen in blood?
incorrect
20.
Saturation
A.
patients minute ventilation must increase
B.
inspired partial pressure of oxygen (PIO2)
C.
measure of proportion of available Hb that is actually carrying oxygen
D.
alveolar PO2 lower, PCO2 higher than normal
E.
V/Q imbalances have a greater effect on oxygenation than on carbon dioxide removal.
F.
increase and promote oxygen unloading
G.
gass pressure gradients
H.
left. HbF has a greater affinity for oxygen than does normal adult Hb
I.
left
J.
hypercapnia and respiratory acidosis
K.
enough normal Hb in the blood
L.
both excess wated ventilation and poor oxygentation. Because the imbalance impairs O2 exchange and PaO2 is reduced
M.
influence of oxyhemoglobin saturation on CO2 dissociation
N.
CaO2=(0.003*PO2)+(Hbtot*1.34*SO2)
O.
If the arterial blood O2 content is decreased, if cardiac output or perfusion is decreased, or if abnormal cellular function prevents proper uptake of O2
P.
5-10 mm Hg less
Q.
PAO2= FIO2*(PB -47)-(PACO2/0.8)
R.
the greater the surface area, diffusion constant, and pressure gradient, the more diffusion will occur
S.
Dissolved oxygen= PO2*0.003
T.
1.right to left shunts in pulmonary and cardiac circulation 2.regional differences in pulmonary ventilation and blood flow
Type the Answer that corresponds to the displayed Question.
incorrect
21.
Carbon dioxide hasa the capacity to chemically cobine with free amino groups of protein molecules forming a?
incorrect
22.
How long does blood take to flow through the pulmonary capilary?
incorrect
23.
Any disorder that lowers alveolar ventilation relative to metabolic need impairs?
incorrect
24.
In pulmonary diffusion PvO2 is how many mm HG?
incorrect
25.
Normal range for cardiac output
incorrect
26.
In pulmonary diffusion Mean PaCO2 is approximately how many mm Hg?
Type the Question that corresponds to the displayed Answer.
incorrect
27.
form of hypoxia in which cellular uptake of O2 is abnormally decreased
incorrect
28.
oxygen molecules bind to Hb by way of ferrous iron ion and coverted to it's oxygenated state
incorrect
29.
chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water
incorrect
30.
abnormal form of the molecule where the heme-complex normal ferrous iron ion loses an electron and oxidizes to its ferric state.
