Sample Values
| Measure | Sample value at rest | Sample value moderate exercise |
|---|---|---|
| Tidal volume | 0.5 L | 3.0 L |
| Respiratory rate | 12 breaths/minute | 30 breaths/minute |
| Minute ventilation | 6.0 L/min | 90 L/min |
| Dead space | 0.15 L | 0.15 L |
| Dead space ventilation | 1.8 L/min | 4.5 L/min |
| Alveolar ventilation | 4.2 L/min | 85.5 L/min |
Pulmonary ventilation may be evaluated using a breathing tube or spirometer, measuring the movement of the chest and abdominal walls using respiratory inductance plethysmography or by isolating the subject in an enclosed metabolic chamber.

Famous quotes containing the words sample and/or values:
“All that a city will ever allow you is an angle on it—an oblique, indirect sample of what it contains, or what passes through it; a point of view.”
—Peter Conrad (b. 1948)
“We cannot spare our children the influence of harmful values by turning off the television any more than we can keep them home forever or revamp the world before they get there. Merely keeping them in the dark is no protection and, in fact, can make them vulnerable and immature.”
—Polly Berrien Berends (20th century)
