QuestionAnswer
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood O2
Normal pH of the blood
T/F: An increase in respiratory rate ALWAYS increases alveolar gas exchange or alveolar ventilation.
Calculated by multiplying tidal volume x respiratory rate
_______ partial pressure of O2 is calculated by [(atmospheric pressure- water pressure) X FIO2]
defined as the volume of air held in the conducting airways during each tidal volume breath (not used for gas exchange)
main blood acid
high blood pH
an increase in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
_______ partial pressure of O2 is calculated by [(inspired partial pressure of O2) - (pCO2/R)]
calculated by taking the ratio of CO2 produced over the O2 consumed.
normal tidal volume (mL)
defined as (tidal volume - anatomic dead space) x respiratory rate
as you increase in altitude, what happens to barometric pressure? (increases or decreases)
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
QuestionAnswer
atmospheric partial pressure of oxygen @ sea level (mm Hg)
low blood pH
blood oxygen levels (mm Hg)
amount of air that is breathed in and out each minue
ventilation _____ (increases or decreases) with an increase in pCO2

alveolar partial pressure of oxygen @ sea level (mm Hg)
increase in Respiratory rate without an increase in alveolar ventilation is known as _____.
increase in respiratory rate with an increase in alveolar ventilation
amount of air that makes it into the alveolar airways
What factor is most important in determining alveolar gas composition? (Tidal Volume or Respiratory Rate)
inspired partial pressure of oxygen @ sea level (mm Hg)
