- Point red outlet towards subject

How many time should exercise 3 be performed?

Test should be performed 3 times by subject

In exercise 4 how long is room air and calibration gas sampled for?

- Room air = 10s

- Calibration gas = 15s

Explain the treatments for exercise 5 (6)

- At end of normal breath, exhale continuously as demonstrated by the intrsuctor to collect an alveolar gas sample

- Breath hold at end of normal inspiration
