Respiratory2

Question 1

Why is the Right lung more susceptible than left lung for inhaled foreign bodies?

Answer 1

Right main stem bronchus is Wider and more Vertical

Question 2

If you aspirate a peanut while upright, where will it end up?

Answer 2

Lower portion of Right Inferior lobe

Question 3

If you aspirate a peanut while supine, where will it end up?

Answer 3

Superior portion of Right Inferior lobe

Question 4

What is the relation of the pulmonary artery to the Right bronchus at the hilum? Left bronchus?

Answer 4

Right - Pulmonary A. is Anterior to bronchus Left - Pulmonary A. is Superior to bronchus “RALS - Right Anterior; Left Superior”

Question 5

What are the structures that pierce the diaphragm? At what level?

Answer 5

“I ate ten eggs at twelve” IVC - T8 Esophagus, Vagus - T10 Aorta, Thoracic duct, Azygos vein - T12 - “at T-1-2 its red, white, blue”

Question 6

What innervates the Diaphragm?

Answer 6

C3, C4, C5 (Phrenic n.) “C3,4,5 keeps the diaphragm alive”

Question 7

Where does pain in the diaphragm refer to?

Answer 7

Shoulder (C5) Trapezius ridge (C3,C4)

Question 8

Quiet breathing (muscles): - Inspiration = - Expiration =

Answer 8

Inspiration = Diaphragm Expiration = Passive (no muscles)

Question 9

Exercise breathing (muscles): - Inspiration = (3) - Expiration = (5)

Answer 9

Inspiration: - External Intercostals - Scalene muscles - Sternocleidomastoids Expiration: - Rectus Abdominis - Internal/External Obliques - Transversus Abdominis - Internal Intercostals

Question 10

Inspiratory Reserve Volume (IRV)

Answer 10

Air that can be breathed in after normal inspiration

Question 11

Tidal Volume (TV)

Answer 11

Air that moves into lung with each quiet inspiration *Typically 500 mL

Question 12

Respiratory Reserve Volume (ERV)

Answer 12

Air that can still be breathed out after normal expiration

Question 13

Residual Volume (RV)

Answer 13

Air in lung after maximal expiration *Cannot be measured on spirometry RV ~ 1.2 L

Question 14

Inspiratory Capacity (IC)

Answer 14

Inspiratory Reseve Volume + Tidal Volume

Question 15

Functional Residual Capacity (FRC)

Answer 15

Residual Volume + Expiratory Reserve Volume *Volume in lungs after normal expiration

Question 16

Vital Capacity (VC)

Answer 16

Tidal Volume + Inspiratory Reserve Volume + Expiratory Reserve volume *Maximum volume of gas that can be expired after a maximal inspiration

Question 17

Total Lung Capacity (TLC)

Answer 17

IRV + TV + ERV + RV *Volume of gas present in lungs after a maximal inspiration
