16. Ventilation Oxygenation Respiration
Physical Act of
moving air into and
out of the lungs
Process of Loading
oxygen molecules
onto hemoglobin
molecules
Process of
exchanging oxygen
and carbon dioxide
18. External
Pulmonary Respiration
Exchange of oxygen and
carbon dioxide between the
alveoli and blood in the
capillaries
Internal
Cellular Respiration
Exchange of oxygen and
carbon dioxide between the
circulation and cells
Respiration
19. Hypoxic Hystotoxic Stagnant
Not enough oxygen
entering lungs
(Low FIO2)
Inability of the
oxygen to load or
unload from
hemoglobin
Hemoglobin are not
being transported to
cells
Hypoxia
25. Tidal Volume Dead Space
Alveolar Volume
Amount of air moved into the
respiratory tract with one
breath
Portion of Tidal Volume that
does not reach the alveoli
How much tidal volume that
participates in gas exchange
Respiratory Rate Alveolar
Volume
Alveolar Minute
Volume
The amount of time a person
breaths in one minute
The amount of air moved
into the alveoli during one
breath
The amount of air that
participates in gas exchange
within one minute
26. Hypoventilation
Builds up Carbon Dioxide
HyperVentilation
Blows off Carbon Dioxide
Factors Affecting Ventilation
CO2 (HyperCarbia) CO2 (hypocarbia)
If patient is alkalotic, patient
may hypoventilate to Retain
CO2
If patient is acidotic, patient
may hyperventilate to
Blow off CO2
108. Standard

*if suspicion of respiratory infection
you should wear a face shield and
gown*
