How to Play
QuestionAnswer
amount of air that makes it into the alveolar airways
low blood pH
inspired partial pressure of oxygen @ sea level (mm Hg)
alveolar partial pressure of oxygen @ sea level (mm Hg)
amount of air that is breathed in and out each minue
defined as (tidal volume - anatomic dead space) x respiratory rate
T/F: An increase in respiratory rate ALWAYS increases alveolar gas exchange or alveolar ventilation.
increase in Respiratory rate without an increase in alveolar ventilation is known as _____.
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
blood carbon dioxide levels (mm Hg)
as you increase in altitude, what happens to barometric pressure? (increases or decreases)
an increase in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
main blood acid
defined as the volume of air held in the conducting airways during each tidal volume breath (not used for gas exchange)
an increase in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood O2
QuestionAnswer
Calculated by multiplying tidal volume x respiratory rate
ventilation _____ (increases or decreases) with an increase in pCO2
calculated by taking the ratio of CO2 produced over the O2 consumed.
What factor is most important in determining alveolar gas composition? (Tidal Volume or Respiratory Rate)
high blood pH
_______ partial pressure of O2 is calculated by [(inspired partial pressure of O2) - (pCO2/R)]
atmospheric partial pressure of oxygen @ sea level (mm Hg)
normal tidal volume (mL)
blood oxygen levels (mm Hg)
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood O2
increase in respiratory rate with an increase in alveolar ventilation
_______ partial pressure of O2 is calculated by [(atmospheric pressure- water pressure) X FIO2]
main blood base
______ partial pressure of O2 is calculated by atmospheric pressure X FIO2
Normal pH of the blood
