Tidal volume = amount of air inhaled per breath during normal breathing
Inspiratory reserve volume = amount of air that can be inspired above and beyond that inspired during a normal quiet inspiration
Expiratory reserve volume = maximal amount of air that can be expired following a normal quiet expiration
Residual volume = amount of air left in the lungs after a maximal expiratory effort
Match each of the lung volumes or capacities identified in the figure with its appropriate name.

Options:
-Vital Capacity
-Tidal Volume
-Residual Volume
-Total Lung Capacity
-Inspiratory Reserve Volume
A = Tidal Volume
B = Inspiratory Reserve Volume
D = Residual Volume
A+B+C = Vital Capacity
A+B+C+D = Total Lung Capacity

FEV1
FEV3
RIGHT:
75-85%
0.5 liters
4.6 liters
>97%
6.0 liters
Tital volume at rest = 0.5 liters
Total lung capacity in men = 6.0 liters
Total lung capacity in women = 4.6 liters
FEV1 = 75-85%
FEV3 = >97%
BTPS refers to:
a) body temperature, ambient pressure, saturated gas
b) body temperature, standard pressure (760 mm Hg)
c) room temperature, ambient pressure, gas at ambient humidity
d) standard temperature; gas at ambient humidity, standard pressure
a) body temperature, ambient pressure, saturated gas
Given the data shown in the following chart, what is the subject’s percent of predicted vital capacity.
92%
1.08 %
108%
Cannot be determined from the information given.
108%
A subject exhales 7.9 liters in one minute. The BTPS factor for the room temperature is 1.18. What is the subject’s ventilation corrected for BTPS? Round your answer to the nearest 1/10.
9.3
Given the data in the chart below, what is the subject’s FEV1 measured in %?
90
Your subject has a forced vital capacity of 4.9 liters and a predicted vital capacity based on age, height and gender of 4.5 liters. What is their percent of predicted vital capacity? Record your answer to the nearest percent.
109
Calculate the volume in liters that a subject exhaled in one second if their vital capacity is 4.4 liters and their FEV 1 is 82 percent. Calculate to the nearest 1/10 liter.
3.6
Evaluate this subject’s airway resistance.
a) Airway resistance is greater than normal.
b) Airway resistance is less than expected.
c) Airway resistance is within the normal range.
d) Cannot be determined from information provided.
b) Airway resistance is less than expected.
The data in the chart below was collected during a ventilation experiment like the one done in the laboratory. Calculate the parameters listed in the left column and match with the correct response from the right column.
LEFT:
Initial breaths/min
End breaths/min
Mean breaths/min
3 minute volume corrected for BTPS
Ventilation
Tidal volume
RIGHT:
7.27 liters/min
12 breaths/min
0.56 liters/breath
21.82 liters
14 breaths/min
13 breaths/min
Initial breaths/min = 14 breaths/min
End breaths/min = 12 breaths/min
Mean breaths/min = 13 breaths/min
3 minute volume corrected for BTPS = 21.82 liters
Ventilation = 7.27 liters/min
Tidal volume = 0.56 liters/breath
The composition of room air:
a) varies with altitude.
b) is ~17% O2, ~4% CO2, and 79% N2.
c) is 20.93% O2, 0.04% CO2, and 79% N2.
d) both a and c are true.
c) is 20.93% O2, 0.04% CO2, and 79% N2.
Your subject has a total expired volume of air of 16 liters over 3 minutes (liters/3 minutes). You determine their breath rate to be 13 breaths per minute. Calculate his tidal volume in liters per breath. Record answer to the nearest 1/10 unit.

-Changes in blood levels of CO2 and O2
-Change in VE (breath rate and/or tidal volume) to bring CO2 and O2 levels back toward steady state
-Sensory neurons from chemoreceptors to Respiratory center
-Sympathetic and parasympathetic neurons to bronchiole smooth muscle
-Respiratory Center in medulla and pons
-Bronchiole smooth muscle, diaphragm, intercostal muscles
-Chemoreceptors located in aortic arch and carotid sinus
Stimulus = Changes in blood levels of CO2 and O2
Receptors = Chemoreceptors located in aortic arch and carotid sinus
Afferent Pathway = Sensory neurons from chemoreceptors to Respiratory center
Integrator = Respiratory Center in medulla and pons
Somatic Efferent Pathway = Neurons to diaphragm and intercostal muscles
Autonomic Efferent Pathway = Sympathetic and parasympathetic neurons to bronchiole smooth muscle
Effectors = Bronchiole smooth muscle, diaphragm, intercostal muscles
Response = Change in VE (breath rate and/or tidal volume) to bring CO2 and O2 levels back toward steady state
