RESPIRATION LungVolumE

Question 1

tidal volume

Answer 1

• normal inspiratory (500ml) and expiratory volume

Question 2

force vital capacity

Answer 2

• maximum volume of air that can be expired

Question 3

residual volume

Answer 3

• air volume remained after force vital capacity

Question 4

functional residual capacity

Answer 4

• air left in the lung after normal expiration

Question 5

inspiratory capacity

Answer 5

• volume inhaled maximally after normal expiration

- maximum inspired volume in a normal person

Question 6

total lung capacity

Answer 6

= FVC + RV

= FRC + IC

Question 7

RR from 15 cpm to 44 cpm

Answer 7

• rapid and shallow

- ACIDOTIC

Question 8

respiratory zone

Answer 8

• exchange of gases takes place
• ALVEOLI ARE FOUND
• ALVEOLAR DEAD SPACE
• no blood flow in the surrounding capillaries

Question 9

conducting zone

Answer 9

• airways
• trachea
• bronchioles
• NO exchange of gases takes place
• PHYSIOLOGICAL DEAD SPACE/ dead zone: normal person measure 150 ml
• CO2- LEAST during expiration room air
• CO2- NO on normal atmosphere
• O2
• NITROGEN DURING EXPIRATION

Question 10

rapid and shallow breathing

Answer 10

• CONDUCTING ZONE
• depressed alveolar ventilation
• source of CO2 blood to the alveoli
• alveolar ventilation
• ACIDOTIC

Question 11

HYPERVENTILATING/ deep ventilation

Answer 11

• ALVEOLAR INVOLVEMENT

- RESPIRATORY ZONE

Question 12

TOTAL VENTILATION

Answer 12

= conducting zone + respiratory zone x RR

Question 13

total ventilation

Answer 13

= conducting zone + respiratory zone = tidal volume (500ml/min) RR 15cpm= normally a person has 7,500 ml/min

Question 14

alveolar ventilation

Answer 14

= tidal volume - dead space x RR
= 500 - 150 mm x 15 cpm
= 5,250 ml/min AMOUNT REACHED INTO THE ALVEOLI

Question 15

2000ml

Answer 15

lost in the dead space

Question 16

increase in DEAD SPACE is inverse to alveolar ventilation

Answer 16

• decrease alveolar ventilation
• not blowing CO2
• increase PACO2

Question 17

pathological increased DEAD SPACE

Answer 17

• EMPHYSEMA
• increase PACO2
• hypercapnea
• acidosis

Question 18

TIDAL VOLUME
pt A 400

pt B 200

higher PO2= pt A
higher PCO2= pt B
higher pH= pt A

Answer 18

RESPIRATORY RATE
10 increase O2

20 increase PCO2

Question 19

respiratory rate (CO2)

Answer 19

• higher more conducting zone
• increase CO2= low pH
• decrease O2

Question 20

depth (O2)

Answer 20

• higher more respiratory zone
• decrease CO2= high pH
• increase O2

Question 21

CO2 is inverse to

Answer 21

• pH

Question 22

a NORMAL PERSON during EXPIRATION which of the ff is least likely or not expected to be found in a conducting zone

Answer 22

• LEAST CO2 in room air temperature

Question 23

a NORMAL PERSON during INSPIRATION which of the ff is least likely or not expected to be found in a conducting zone

Answer 23

• NO CO2 in normal atmosphere
