2. Another type of ventilator graphic is called a loop. These are displays of two variables plotted on the x-y coordinates.




incorrect
3. The purpose of ventilator graphics includes all of the following except ____.




incorrect
4. The pressure (PIP) required to ventilate the patient increased




incorrect
5. What is the normal central venous pressure reading?




incorrect
6. The relationship, "the pressure delivery to the lungs will depend on the stiffness of the lung," can be graphically and mathematically represented as ____.




incorrect
7. 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
8. 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
9. Which of the following is NOT associated with an increase in central venous pressure?




incorrect
10. 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) ____.
