Expert Solution

Qn1.

Spirometer is an apparatus which measures the volume of expiratory and inspiratory air from the lung.

RV and TLC cannot be measured by Spirometer.

RV is Residual Volume. It is the amount of air remains in the lung after a full exhalation. TLC is the total lung capacity , the maximum amount of air a lung can accommodate. This two Volume cannot be measured by spirometer.

ERV is the Expiratory reverse Volume. The volume of air that can be exhale forcibly after normal exhalation.

Qn2.

Tidal volume represents the volume of air moves in or out of the lung during each normal respiratory cycle. Average tidal Volume for an adult human is 7ml/kg body mass.

A client weigh 90kg. His tidal volume average will be (7×90=630ml) None of the above.

Qn3.

FRC is the functional residual capacity of the lung. The amount of remaining air in the lung after a normal expiration.

The FRC is approximately (a) 2.3liters

Qn4.

The residual volume is approximately (d) 1.2 liters
