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