Q

On the spirometry volume vs. time curve, what are the curve desscriptions of normal, asthma and COPD?

A

Normal maintains FVC and has the steepest initial slope
Asthma maintains FVC however has a gentler slope than normal
COPD has a lower FVC and has the gentlest slope

17
Q

What are 3 types of exercise testing?

A
  1. FEV1 or PEF post exercise
  2. SaO2 during exercise
  3. Full Cardiopulmonary Exercise Test (CPET)
18
Q

A

Decreased FEV1 or decreased post exercise

19
Q

What is monitored in exercise testing for interstitial lung disease?

A

20
Q

What is CPET used to differentiate?

A

21
Q

What can be used to measure functional residual capacity?

A

Helium dilution/N2 washout

22

31
Q

What are whole body plethysmography or impulse oscillometry used to measure?

A

Airway resistance

32
Q

What measures airway resistance during quiet tidal breathing?

A

33
Q

What is exhaled breath nitric oxide a non-invasive marker of?

A

Eosinophilic airway inflammation in asthma

34
Q

What is nitric oxide suppressed by in COPD?

A
