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