Respiratory Exam 1 - Jones - Ventilation, Gases, and perfusion

What device measures volume of moving air into and out of the lungs

• spirometer

• ventelator

• inhaler

• decompressor

Match the following areas of pulmonary ventilation

c

d

e

f

a

b

Total lung capacity

Residual volume (RV)

Vital capacity

Expiratory Reserve Volume (ERV)

Tidal volume (TV

Inspiratory reserve volume (IRV)

Match the following

• Volume of air in lungs at rest

• Functional residual capacity

• Volume of air which moves in and out of lungs during a breath

• Residual volume

• Volume of air left in longs following max expiration

• Tidal volume (TV)

• expire quietly then expire more via forced

• Expiratory reserve volume (ERV)

Match the following

• Most we can inspire and expire

• Vital capacity

• Forcefully inspiring air

• Inspiratory capacity

• Max volume of air lungs can hold (adults about 6 L)

• Total lung capacity (TLC)

• Total inspiratory volume

• Inspiratory reserve volume

Which of the following are possible places for dead space (select all that apply)

• poorly ventilated areas

• Due to air left in conducting airways

• Areas with proper blood floow

• Properly ventilated areas

If PE_co2 = 30 mm Hg and Pa_co2 = 42 mm Hg and the tidal volume is 450 ml what would the anatomical dead space be? (rounded to the nearest whole number)

• 129 mL

• 150 mL

• 450 mL

• 119 mL

Match the following equations with their proper names

• F = ΔP / R

• Flow

• V_D = TV - (PE_Co2 * TV) / Pa_co2

• Minute venilation

• V_A=ƒ*(V_T-V_D)

• Total dead space

• V_E=ƒ*TV

• Alveolar Ventilation

A person is breathing 15 times per minute with a tidal volume of 500 mL what is there minute ventilation

• 7500 L/min

• 7.5 L/min

• 7.5 mL/min

• 15 breaths/min

The atmospheric pressure a location was found to be 800 mm Hg match the following gases at this level for inhaling and exhaling

• 632 mm Hg

• Carbon dioxide

• 0 mm Hg

• Nitrogen

• 168 mm Hg

• Oxygen

Calculate the oxygen of inspired air once water is added to it when the atmospheric pressure is 800 mm Hg

• 138 mm Hg

• 632 mm Hg

• 158 mm Hg

• 168 mm Hg
