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