Q
Spirometry #1
- Measures how ____ and how _____
- So it’s a common simple test, but is it mechanical or digital?
- Is the info from spirometry enough to diagnose someone?
A
-
2
Q
Spirometry #2
- Tell me about what these volumes mean, where they are on the graph of spiromtery?
- what’re their general values?
- what muscles are involved with inspiration and expiration reserve volumes
- why is ERV smaller than IRV? - What is FVC?
- how is it different to vital capacity in general? - What is FRC?
- why is this the equilibrium? - What is RLV?
- how to measure this?
A
- FVC is jsut VC when you force it out
- Equil because it’s at the end of tidal - dont need to inspire extra or expire extra for thsi

Q
Spirometry #3
- What do forced measurements give info about?
- What ratio is used to define obstruction?
- Okay so how do you do the forced expiratory manouvre?
- What do normal predicted values for spirometry depend on? There are three things
- So what are the normal values compared with predictted?
- FVC
- FEV1
- FEV1/FVC ratio
A

Q
Spirometry #4
- What is it dependent on? Like in terms of the measurement
- What 3 acceptable attempts do you take?
- What are flow volume loops?
- assessment of what?
- what will specific ptterns tell you?
A
=

Q
Peak Expiratory Flow Rates
- What is it?
- What values does it give?
- Where do you determine normal values?
- so what part of this measruement is useful? - So what’re the indications for pulmonary function testing whether that be PEFR or not?
A

Q
What the difference between obstrctive vs restructive diseases?
- are they the only two types?
- what are examples
- what happens to FVC, FEV1, ratio and volume measurements?
A
