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