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