Lecture - Resp (Bevin Physiol 2)

Question 1

Spirometry #1

1. Measures how ____ and how _____
2. So it’s a common simple test, but is it mechanical or digital?
3. Is the info from spirometry enough to diagnose someone?

Answer 1

-

Question 2

Spirometry #2

1. 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?
2. What is FVC?
   - how is it different to vital capacity in general?
3. What is FRC?
   - why is this the equilibrium?
4. What is RLV?
   - how to measure this?

Answer 2

2. FVC is jsut VC when you force it out
3. Equil because it’s at the end of tidal - dont need to inspire extra or expire extra for thsi

Question 3

Spirometry #3

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

Question 4

Spirometry #4

1. What is it dependent on? Like in terms of the measurement
2. What 3 acceptable attempts do you take?
3. What are flow volume loops?
   - assessment of what?
   - what will specific ptterns tell you?

Answer 4

=

Question 5

Peak Expiratory Flow Rates

1. What is it?
2. What values does it give?
3. Where do you determine normal values?
   - so what part of this measruement is useful?
4. So what’re the indications for pulmonary function testing whether that be PEFR or not?

Question 6

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?
