RESPIRATION LungVolumE Flashcards
1
Q
tidal volume
A
- normal inspiratory (500ml) and expiratory volume
2
Q
force vital capacity
A
- maximum volume of air that can be expired
3
Q
residual volume
A
- air volume remained after force vital capacity
4
Q
functional residual capacity
A
- air left in the lung after normal expiration
5
Q
inspiratory capacity
A
- volume inhaled maximally after normal expiration
- maximum inspired volume in a normal person
6
Q
total lung capacity
A
= FVC + RV
= FRC + IC
7
Q
RR from 15 cpm to 44 cpm
A
- rapid and shallow
- ACIDOTIC
8
Q
respiratory zone
A
- exchange of gases takes place
- ALVEOLI ARE FOUND
- ALVEOLAR DEAD SPACE
- no blood flow in the surrounding capillaries
9
Q
conducting zone
A
- 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
10
Q
rapid and shallow breathing
A
- CONDUCTING ZONE
- depressed alveolar ventilation
- source of CO2 blood to the alveoli
- alveolar ventilation
- ACIDOTIC
11
Q
HYPERVENTILATING/ deep ventilation
A
- ALVEOLAR INVOLVEMENT
- RESPIRATORY ZONE
12
Q
TOTAL VENTILATION
A
= conducting zone + respiratory zone x RR
13
Q
total ventilation
A
= conducting zone + respiratory zone = tidal volume (500ml/min) RR 15cpm= normally a person has 7,500 ml/min
14
Q
alveolar ventilation
A
= tidal volume - dead space x RR
= 500 - 150 mm x 15 cpm
= 5,250 ml/min AMOUNT REACHED INTO THE ALVEOLI
15
Q
2000ml
A
lost in the dead space
