Q. No.A measure of the amount of air a person inhales during a normal breath is:
| 1. inspiratory reserve volume | 2. vital capacity |
| 3. total lung capacity | 4. tidal volume |
The amount of air that remains in a person's lungs after fully exhaling is known as:
| 1. tidal volume | 2. expiratory reserve volume |
| 3. vital capacity | 4. residual volume |
Regarding pulmonary capacities, the maximum volume of air a person can breathe in after a forced expiration can also be defined as:
1. Total volume of air a person can inspire or expire after a normal inspiration or expiration
2. Volume of air that will remain in the lungs after a normal expiration
3. Maximum volume of air a person can breathe out after a forced inspiration
4. Total volume of air accommodated in the lungs at the end of a forced inspiration
The value of which of the following is normally the highest in normal physiological conditions?
| 1. | Residual volume | 2. | Expiratory reserve volume |
| 3. | Functional residual capacity | 4. | Inspiratory reserve volume |
Under normal physiological conditions, the maximum volume of air a person can breathe out after a forced inspiration in a healthy human being is about:
| 1. | 2300 ml | 2. | 3500 ml |
| 3. | 4600 ml | 4. | 5800 ml |
Which of the following equations regarding the calculation of pulmonary capacities would be correct?
| 1. IC = IRV – TV | 2. EC = VC – IRV |
| 3. VC = ERV + IRV | 4. TLC = VC – RV |
The sum of expiratory reserve volume [ERV] and residual volume [RV] corresponds to:
| 1. Expiratory capacity | 2. Vital capacity |
| 3. Functional residual capacity | 4. Total lung capacity |
The figure shows pulmonary volumes as measured on a spirometer. Which of the following will be true?
| I: | A+B = Inspiratory Reserve Volume |
| II: | C+D = Functional Residual Capacity |
| III: | B+C = Tidal Volume |
| IV: | [(A+B+C+D) – (A+B+C)] = Residual Volume |
2. Only II and IV are correct
3. Only I and III are correct
4. I, II, III and IV are correct
