3
Difference between arterial systolic and diastolic pressure is?
Pulse Pressure
4
Blood pumped by the ventricles in one contraction is?
Stroke Volume
5
CVP is?
Right ventricular Preload
6
Pulmonary Arterial Pressure
Right ventricular afterload
7
Average blood pressure in the Arterial circulation?
Mean arterial pressure
8
End-diastolic stretch of the muscle fiber is?
Preload
9
Resistance of the blood vessels into which the ventricles is pumping blood?
Afterload
10

Subclavian
15
Arterial location is?
Within systemic arterial near insertion site
16
Central venous insertion site?
Subclavian or internal jugular vein
17
Pulmonary artery insertion site
subclavian or internal jugular vein
18
Central Venous location
Superior Vena cava or within right atrium
19
Pulmonary Artery common uses except;
Administer fluid or medication
20
Normal Arterial pressure values of systolic?
100-140 mm Hg
21
Normal Arterial pressure values of diastolic?
60-90 mm Hg
22
Mean arterial pressure formula?
MAP = (P systolic + 2 x P diastolic)/3
23
Normal pulse pressure is?
30 mm Hg to 40 mm Hg
24
High ( Wide) pulse pressure is?
>40 mm Hg
25
In elderly patients a __ mm Hg rise in pulse pressure increases the risk of major cardiovascular complication and mortality by about __ %
10 mm Hg and 20%
26
___________ may also lead to a higher pulse pressure because a slow heart rate allows the blood volume more time for diastolic runoff and causes a lower diastolic pressure.
Bradycardia
27
Low (Narrow) Pulse pressure is?
<30 mm Hg
28
___________ may also lead to a lower pulse pressure because a high heart rate provides less time for diastolic runoff and causes higher diastolic pressure.
Tachycardia
29
Conditions leading to High pulse pressure except
Low stroke volume - Congestive heart failure
30
Conditions Leading to Low Pulse pressure except
Noncompliant blood vessels - arteriosclerosis
31
Potential Problems with arterial Catheter. Air bubbles in tubing / Loose tubing connections

33
Potential Problems with arterial Catheter. Transducer and catheter placed lower than measurement site
Measurement higher than actual
34
Potential Problems with arterial Catheter. Inadequate pressure applied to the flush solution bag
Backup of blood in the tubing
35
Potential Problems with arterial Catheter. Blood clot at the catheter tip, catheter tip blocked by wall of artery
Inaccurate reading, signal interference
36
Decrease CVP except
Hypervolemia
