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