QuestionSBA
QuestionChoice
Inspiratory capacity is the maximum amount of air that can be inspired after the conclusion of a normal expiration. It is the sum of the tidal volume and inspiratory reserve volume (3.0 L + 480 ml).

a
3.48 L
QuestionChoice
This is the patient's vital capacity, which is the sum of tidal volume, inspiratory respiratory volume and expiratory volume. This is defined as the volume of air that can be breathed in during maximum inspiration following a maximum expiration.

b
4.33 L
QuestionChoice
This is the average total lung capacity of a human. It is calculated by the summation of vital capacity and residual lung volume and cannot be recorded by spirometry alone.

d
6 L
QuestionChoice
This is the value of Expiratory Respiratory volume minus tidal volume. This is not a recorded volume in spirometry.

A 27-year-old male presents to General Practice complaining of wheeze.

Spirometry is performed with the following results:

 - Tidal Volume: 480 ml
 - Inspiratory Respiratory Volume: 3.0 L
 - Expiratory Respiratory Volume: 850 ml

Which of the following is the patient's inspiratory capacity?
