The respiratory volume that cannot be measured using spirometer is
Expiratory reserve volume.
Residual Volume
Inspiratory Reserve Volume
Tidal Volume
The residual volume that cannot be measured using the spirometer because it is impossible to completely breath out.
In breathing movements, air volume can be estimated by
(a) stethoscope
(b) hygrometer
(c) sphygmomanometer
(d) spirometer
A patient exhales normally, then, using forced ventilation, the patient blows as much air as possible into a spirometer. This would measure the:
