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