3. Select a subject. To enable some degree of standardisation the subject should be
rested for 30 minutes and should not have eaten a meal for the previous 2 hours.
4. Fit a sterilised mouthpiece to the T piece, seat the subject comfortably and place
the mouthpiece and nose clip in position.
5. Allow thw subject to become accustomed to breathing through the tubes and
then at the end of an outward breath turn the valve to SPIROMETER and begin
recording.
Suggested Investigation 1
Normal tidal volume, respiratory rate and pulmonary ventilation.
1. Allow the subject to breathe normally through the mouthpiece (they should not
be able to see the trace).
2. Continue recording the trace for one minute or until its completed whichever is
shorter.
3. Normal tidal volume: is given by the amplitude of the trace.
4. Respiratory rate: the number of breathes per minute or more formally the number
of movements indicative of inspiration and expiration is usually determined by
counting the number of times the chart rises or falls per minute.
#Newborns: average 44 breathes/minute
#Infants: average 20-40 breathes/minute
#Preschool children: 20-30 breathes/minute
#Older children: 16-25 breathes/minute
#Adults: 14-18 breathes/minute
5. Pulmonary ventilation: is the volume of air moved and is found by multplying aver-
age tidal volume by respiratory rate.
Suggested Investigation 2
Reserve volumes and vital capacity
1. After a normal breath ask the subject to take the deepest possible inward breath
and the the deepest possible outward breath.
2. These peaks give the inspiratory and expiratory: reserve volume.
3. The total volume from maximum to minimum is the vital capacity.
Suggested Investigation 3
Oxygen Consumption
1. Seat the subject comfortably and allow them to breathe normally through the
mouthpiece.
