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