Answer 2

Left 2nd intercostal space at the sternal border

Question 3

Auscultation of tricuspid valve

Answer 3

Left 4th intercostal space at the sternal border

Question 4

Auscultation of mitral valve

Answer 4

Left 5th intercostal space at the sternal border

Question 5

Tidal volume

Answer 5

• Total volume of air that moves in and out of the lungs during quiet breathing
• Approximately 10% of total lung volume

Question 6

Inspiratory Reserve Volume

Answer 6

• Maximum volume of air that can be inspired after normal tidal volume inspiration.
• Approximately 50% of total lung volume

Question 7

Expiratory Reserve Volume

Answer 7

• Maximum volume of air that can be expired after a normal tidal expiration.
• Approximately 15% of total lung volume

Question 8

Residual Volume

Answer 8

• Volume of air still remaining in the lungs at the end of a maximal expiration.
• Approximately 25% of total lung volume

Question 9

Anatomic dead space volume

Answer 9

• Volume of air that occupies the non-respiratory conducting airways

Question 10

Total Lung Capacity

Answer 10

• The max volume of air the lungs can hold
  TLC = TV + IRV + ERV + RV

Question 11

Vital Capacity

Answer 11

• Volume of air that can be forcibly moved in and out of the lungs
• Approximately 75% of total lung volume
  VC = TV + IRV + ERV

Question 12

Inspiratory Capacity

Answer 12

• The maximum volume of air that can be inhaled after a normal tidal exhalation.
• Approximately 60% of total lung colume
  IC = TV + IRV

Question 13

Functional Residual Capacity

Answer 13

• The volume of air still in the lungs after a normal exhalation
• Approximately 40% of total lung volume
  FRC = ERV + RV

Question 14

Forced vital capacity

Answer 14

The max volume of air that can be forcibly expired after a forced max inhalation.
