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