Enter the letter for the matching Answer
incorrect
1.
The purpose of ventilator graphics includes all of the following except ____.
incorrect
2.
The following graphic is a ____________________ and represents ___________________.
incorrect
3.
The relationship, "the pressure delivery to the lungs will depend on the stiffness of the lung," can be graphically and mathematically represented as ____.
incorrect
4.
The greater this pressure gradient, the faster the flow of gas and the sooner the lungs fill: this could be graphically and mathematically stated as ____.
incorrect
5.
What is the normal range for mean arterial pressure?
incorrect
6.
What is the normal range for pulmonary capillary wedge pressure?
incorrect
7.
What is the normal range for cardiac output?
incorrect
8.
What is the normal central venous pressure reading?
incorrect
9.
One of the ways of providing mechanical ventilation is the use of a volume-targeted breath with a constant inspiratory gas flow. The resulting flow scalar will be configured as a(n) ____.
incorrect
10.
Scalars displayed during mechanical ventilation include all of the following except ____.
A.
80 to 100 mm Hg
B.
flow vs. volume
C.
2 to 6 mm Hg
D.
5 to 10 mm Hg
E.
rectangular or square wave
F.
ΔP = ΔV/C
G.
4 to 8 L/min
H.
volume scalar, increased expiratory volume and possible dysynchrony
I.
Flow = V/TI
J.
making an assessment of the supply pressures to the ventilator
Type the Answer that corresponds to the displayed Question.
incorrect
11.
Another type of ventilator graphic is called a loop. These are displays of two variables plotted on the x-y coordinates.
incorrect
12.
To reduce the risk of barotrauma on PCV the flow pattern should be set to ____.
incorrect
13.
Between 7 and 11, the patient's airway resistance (Raw) decreased
incorrect
14.
When PC CMV is the mode of ventilation, the resulting flow scalar will be configured as a(n) ____.
incorrect
15.
The pressure (PIP) required to ventilate the patient increased
incorrect
16.
With a constant flow, the rise in volume is expected to be displayed at a non-constant rate.
incorrect
17.
Many of the newer microprocessor ventilators have very high gas pressure sources, in the range of 400 to 700 cm H2O. This is enough pressure to produce a constant flow of gas during inspiration for any clinical situation one might encounter.
incorrect
18.
The alveolar pressure curve will resemble in appearance the volume delivery curve, regardless of the type of volume waveform that is present.
incorrect
19.
Which of the following is NOT associated with an increase in central venous pressure?
incorrect
20.
The curve representing PTA will not always resemble the curve for flow.
