QuestionAnswer
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
Calculated by multiplying tidal volume x respiratory rate
as you increase in altitude, what happens to barometric pressure? (increases or decreases)
increase in respiratory rate with an increase in alveolar ventilation
alveolar partial pressure of oxygen @ sea level (mm Hg)
calculated by taking the ratio of CO2 produced over the O2 consumed.
ventilation _____ (increases or decreases) with an increase in pCO2
blood oxygen levels (mm Hg)
inspired partial pressure of oxygen @ sea level (mm Hg)
increase in Respiratory rate without an increase in alveolar ventilation is known as _____.
low blood pH
_______ partial pressure of O2 is calculated by [(atmospheric pressure- water pressure) X FIO2]
normal tidal volume (mL)
defined as (tidal volume - anatomic dead space) x respiratory rate
atmospheric partial pressure of oxygen @ sea level (mm Hg)
QuestionAnswer
______ partial pressure of O2 is calculated by atmospheric pressure X FIO2
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 makes it into the alveolar airways
blood carbon dioxide levels (mm Hg)
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)
an increase in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood CO2
_______ partial pressure of O2 is calculated by [(inspired partial pressure of O2) - (pCO2/R)]
amount of air that is breathed in and out each minue
T/F: An increase in respiratory rate ALWAYS increases alveolar gas exchange or alveolar ventilation.
main blood acid
Normal pH of the blood
an decrease in alveolar ventilation with unchanged metabolism causes a ____ (increase or decrease) in blood O2
main blood base
