Lung volumes

The respiratory equation:

_____ ______ x frequency = Minute Ventilation

What is Tidal volume?

• The volume of air breathed in and out during one breath

• The maximal amount of air a person can expel

• The amount of blood pumped from the heart

• The additional air that can be forcibly inhaled after normal inspiration

Resting Tidal Volume is around:

• 3000mL

• 2400mL

• 1200mL

• 500mL

The maximum amount of air exhaled following a maximum inhalation

• Vital Capacity

• Total Lung Capacity

• Residual Volume

• Inspiratory Reserve Volume
