define Scalar - ANSWER:used to specify flow, pressure, and volume waveforms that
are graphed relative to time
How many different types of wave forms are produced with scalars in mechanical
ventilation and what are they? - ANSWER:6
1. rectangular (constant
2. descending ramp
3. ascending ramp
4. sinusoidal
5. rising exponential
6. decaying exponential
The flow of gas into the lungs depends on the difference between __________ and
_________ - ANSWER:the pressure from the vent and the pressure inside the lungs
does a greater pressure gradient increase or decrease the flow of gas? -
ANSWER:increase
If there is an increase in flow, the lungs will fill faster or slower? - ANSWER:faster
Flow = - ANSWER:V/Ti
The amount of pressure required to inflate the lungs depends on the patients what?
(2) - ANSWER:1. airway resistance
2. lung compliance
How do stiff lungs effect lung compliance and required pressures? -
ANSWER:Decrease in compliance
higher pressures
Very compliant lungs are easy to inflate and require what kind of pressures? -
ANSWER:low pressures
Change in pressure= - ANSWER:change in volume/lung compliance
What is the most important factor affecting air way resistance? - ANSWER:airway
diameter
If air way resistance decreases the airway diameter will increase or decrease? -
ANSWER:increase (this will also increase flow)
The volume delivered depends on what 2 things? - ANSWER:1. amount of flow
